Executive Summary

In 2011, Building Science Corporation, working under the Building America Program, 

completed research to support the development of standards for testing the airflow resistance of 

insulation materials used in dense-pack retrofit applications. Building America Report 1109, 

High Impact Project: Support of Standards Development – Dense-pack Airflow Resistance, Final 

Research Report, provides a detailed summary of the research program, including a summary of 

airflow resistance test results for 10 cellulose fiber insulation materials. Recently, mineral fiber 

insulation (MFI) materials (glass fiber, stone wool, etc.) have also been developed and/or 

suggested for dense-pack retrofit applications. Testing is needed to support the inclusion of MFI

in new dense-pack air resistance standards.

This report expands on Building America Report 1109 by applying the experimental apparatus 

and test method to dense-pack retrofit applications using MFI materials. Three fiberglass

insulation materials and one stone wool insulation material were tested, and the results compared 

to the cellulose results from the previous study. Test wall specimens were prepared to cover 

densities in the range of roughly 1.8–2.5 pcf. Three installation methods were tested, based on a 

survey of installation instructions provided by a sample of five fiberglass manufacturers: (1) 

bottom fill, using an insertion tube installed up through a hole at approximately 24 in. above the 

bottom plate; (2) top fill, using an insertion tube installed down through a hole at approximately 

6 in. below the top plates; and (3) 2-in. nozzle, installed through two or three holes (e.g., at holes 

approximately 24 in., 72 in., and 90 in. above the bottom plate). 

Airflow resistance varied significantly between loose-fill fiberglass products, even though all the 

compared products are marketed and supported for use in dense-pack retrofit applications. When 

these fiberglass products were installed at approximately 2.2 pcf, the variance was 0.33–1.73 

cfm50/ft2

. The distribution of the installed material, and thus the airflow resistance, also depend 

on installation method. 

Two of the three loose-fill fiberglass products tested (installed at approximately 2.3 pcf) 

produced long-path flow rates of 0.28 and 0.42 cfm50/ft2

 and short-path airflow rates of 0.76 and 

1.1 cfm50/ft2

. These are comparable to the cellulose dense-pack retrofits benchmarks of 0.33 and 

1.0 cfm50/ft2 for the long- and short-path airflow rates, respectively (cellulose fiber insulation 

installed at 3.5 pcf as required by Building Performance Institute). However, the fiberglass test 

walls were prepared using the 2-in. nozzle installation method, not the insertion tube methods 

recommended as best practice for retrofit applications. These results indicate a potential for 

dense-pack applications of MFI, but more work needs to be done to develop appropriate 

standards for real-world installation needs. In particular, further testing should be conducted to 

establish recommended install densities for insertion tube installation methods.

None of the stone wool manufacturers support dense-pack retrofit applications using their 

products. As a result, only one loose-fill stone wool insulation product was collected for testing. 

The stone wool fibers and nodules were too large to successfully install using either of the 

insertion tube techniques. Loose-fill stone wool is not recommended for dense-pack retrofit 

applications.

1 Introduction and Background

1.1 Introduction

This report documents airflow resistance test results for dense-pack retrofit applications using 

mineral fiber insulation (MFI) materials (i.e., glass fiber and stone wool). The test results are 

compared to previous airflow resistance tests for dense-pack retrofit applications using 

10 different cellulose fiber insulation (CFI) materials.

1.2 Background

In the early 1980s, researchers acknowledged and studied the airflow resistance of dense-pack 

CFI in materials in retrofit applications (EDU 1986). In 2011, Building Science Corporation 

(BSC), working under the Building America Program, completed research work to support the 

development of standards for testing the airflow resistance of insulation materials used in densepack retrofit applications. Building America Report 1109, High Impact Project: Support of 

Standards Development – Dense-pack Airflow Resistance, Final Research Report, provides a 

detailed summary of the research program, including the test apparatus and method that were 

developed (Schumacher 2011). The same report also provides a summary of airflow resistance 

test results for 10 CFI materials.

More recently, MFI materials (glass fiber, stone wool, etc.) have been developed and/or 

suggested for dense-pack retrofit applications. Research is needed to develop standards for 

airflow resistance for these new materials. More specifically, testing is needed to support the 

development of two new standards by the Building Performance Institute (BPI): BPI-102, which 

will set requirements for the airflow resistance of insulation used in retrofit cavity (dense-pack) 

installations, and BPI-103, which will define acceptable test methods to measure the airflow 

resistance of insulation materials used in dense-pack applications. 

1.3 Scope of This Work

This report documents airflow resistance test results for three fiberglass insulation materials and 

one stone wool insulation material. 

1.4 Material Sample Identification and Collection

Suitable mineral insulation materials were identified through discussion with weatherization 

industry practitioners, a review of literature from trade publications and online sources, and 

through discussion with a manufacturer experts’ panel from the North American Insulation 

Manufacturers Association.

To begin sample selection, five fiberglass insulation materials were identified as intended for 

and/or used in retrofit wall applications:

• Certainteed’s Optima

• Guardian’s CWI Plus

• Johns Manville’s Spider

• Knauf’s EcoFill-WX

• Owens Corning’s ProPink L77. 
2 

BSC collected six or more sample bags of each fiberglass retrofit product from the respective 

manufacturers. Appendix A includes manufacturer’s literature for each of the products. Three 

fiberglass products were randomly selected from the five products collected. 

Four stone wool insulation manufacturers produce granular/loose-fill products in North America; 

however, none of these are intended for or (to the best of BSC’s knowledge) used in retrofit wall 

applications:

• Amerrock’s RockWool Premium Plus

• Rolan’s Fibra Mineral Nodular 

• Roxul’s Rockfill 

• Thermafiber’s Spray Wool (one of many Granulated Products). 

The stone wool insulation manufacturers were less interested in providing samples, emphasizing 

that their products were not developed for or supported if used in dense-pack retrofits in 

residential applications. BSC was able to collect sample bags from only one of the stone wool 

insulation manufacturers. To maintain anonymity, BSC will not identify the stone wool sample 

that they were able to collect and test. Appendix B includes manufacturer’s literature for each of 

the products.

2 Experimental Apparatus and Method

The dense-pack mineral fiber tests were performed using the same apparatus and method that 

were developed for the dense-pack cellulose fiber tests described by Schumacher (2011). The 

calibration box, electronic scale, test wall assembly, wall balance, and load cell were the same as 

those used for the cellulose testing in 2011. Only the fiber moving machine and installation 

methods were changed. 

2.1 Test Wall Assembly

Figure 1 shows the test wall assembly and the two flow paths that are evaluated during testing: 

the short- and long-flow paths. A fan depressurizes the wall assembly so air is drawn in through 

the air inlet holes in the back panel. The top and bottom inlet holes are used for long path tests; 

the upper and lower inlet holes are used for short-path tests. The air travels through the densepacked insulation and out of the wall assembly at the air outlet slot that is located at mid-height 

on the front panel. The outlet air is collected in a manifold and drawn through a series of flow 

measurement devices before traveling through the fan and being expelled to the laboratory. This 

arrangement maximizes the uniformity of airflow, pressures, and temperatures.

A background leakage test is conducted with the top, bottom, upper and lower inlet holes sealed. 

The top and bottom holes are opened to produce two 45 1⁄4-in. long-flow paths. The top and 

bottom holes are then resealed and the upper and lower holes are opened to produce two 16-in. 

short-flow paths. 

Airflow rates are reported in cfm50/ft2

 where the area is perpendicular to the flow path. Each test 

involves flow paths up through three stud spaces and down through three stud spaces so the total 

flow area is 6 × (3.5 × 14.5 in.) = 304.5 in.2

. 

Figure 1. Schematic of airflow paths through test wall assembly

The installed density is measured with an uncertainty of ± 1% or ± 0.035 pcf. Air pressures are 

measured using an auto-zeroing digital manometer having a measurement accuracy of ± 1% of 

reading. Flow rates are measured using rotometers having uncertainty of ± 2% of reading and 

capable of measuring flow rates down to 5 ± –0.6 scfh. 

Schumacher (2011) provides more detailed explanation of the apparatus, test method, and 

uncertainty. 

2.2 Fiber Moving Machine

A Krendl Model 450A All-Fiber Machine was used to prepare the cellulose fiber test wall 

specimens that Schumacher (2011) described. Several fiberglass test wall specimens had been 

prepared using this machine in 2011; however, the Krendl 450A did not have appropriate mixing 

paddles and shredders to properly condition the fiberglass material for dense-pack applications.

For the purposes of the mineral fiber dense-pack tests, BSC sought to identify and secure a single 

machine that could be used for all planned tests. The team approached members of a 

manufacturer experts’ panel from the North American Insulation Manufacturers Association for 

input, and all agreed that the following small (i.e., portable, not truck-mount) machines were 

appropriate for dense-packing fiberglass insulation: 

• Accu1 9100 series 

• Intec Force 3

• Krendl Model 425 or 475 

• Spray Insulation Components InsulMaxx 2000 or 4000. 

A brand new InsulMaxx 2000 machine, pictured in Figure 2, was secured for the preparation of 

fiberglass and stone wool test wall specimens. The InsulMaxx 2000 has a variable-speed blower, 

and double agitators (one set of shredders and one set of mixing paddles) suitable for 

conditioning fiberglass loose-fill products.

2.3 Manufacturer-Recommended Installation Methods and Densities

Cellulose insulation manufacturers provide few, if any, special instructions for installing their 

products in dense-pack retrofit applications. The installation instructions generally reflect those 

of BPI’s Insulation and Airsealing Technician certification course. These requirements were 

summarized by Schumacher (2011). Appendix C of this report provides an example of one 

cellulose manufacturer’s instructions for installing its product in a dense-pack retrofit 

application. 

Fiberglass manufacturers, similarly, provide relatively little instruction for dense-pack retrofits. 

Table 1 provides a survey of the installation instructions and fill tables/coverage charts for each 

of the five loose-fill fiberglass insulation materials collected. The survey considered information 

on the product packaging and information readily available in the manufacturers’ dense-pack and 

weatherization/retrofit literature. Table 2 provides a survey of the machine and hose 

recommendations for each of the five fiberglass materials. Finally, Table 3 provides a survey of 

the recommended installation methods/techniques for dense-pack and retrofit applications. 

Only one of the five fiberglass products had packaging that included a dense-pack fill table. One 

other provided a fill table for “closed cavities that are compression filled,” which implies densepack application. For these two products the package-recommended dense-pack install densities 

were 2.2 and 1.8 pcf, respectively. The other packages provided recommended install densities 

of 1.0–1.8 pcf for “closed cavities.” 

Where dense-pack installation instructions and fill tables are not provided on the packaging, it is 

reasonable for installers to seek this information online and from their local suppliers. References 

to dense-pack applications were found in the general documentation for four of the five products. 

Most documentation contained statements about the ability to dense pack to a certain density. 

Some documents said to install to “a minimum of” 2.5 pcf; others said install “up to” 2.5 pcf. Yet 

others suggested a range of dense-pack install densities (e.g., 1.8–2.6 pcf). In several cases, the 

recommended dense-pack install densities from the packages did not agree with the separate 

documentation. 

Through discussions with installers, BSC found that some are using installation instructions and 

fill tables from manufacturers’ weatherization and retrofit documentation. This documentation 

provides a third set of install densities that often contradict the information on the packaging and 

in other literature for the same product. The weatherization and retrofit documentation, where 

available, suggests install densities of 1.3–1.8 pcf for one product, 1.6 pcf for another. A third 

product, Knauf EcoFill Wx, instructs weatherization installers to use dense-pack methods and fill 

to 2.2 pcf. 

Loose-fill fiberglass insulation products perform differently from cellulose insulation products. 

Fiberglass products are expected to have dense-pack install densities that are different from and 

lower than those for cellulose materials. Furthermore, there may be a range of dense-pack install 

densities for different fiberglass products.

Only one of the five materials collected had consistent instructions and recommended install 

densities between the packaging, dense-pack documentation and weatherization retrofit 

documentation. In all other cases, the installer is faced with a range of instructions and install 

densities to work toward. Greater clarity and consistency are needed in the installation 

instructions and recommended install densities for fiberglass products used in dense-pack retrofit 

applications.

2.4 Installation Methods and Densities for Test Wall Specimens

The experimental program for this work was modified to address the range of installation 

methods and install densities provided on the material packaging and in other documentation 

from the five loose-fill fiberglass insulation manufacturers. None of the stone wool insulation 

manufacturers support dense-pack applications, so none provided any directions or target 

densities for this application. The same insulation techniques and target densities were used for 

fiberglass and stone wool products. 

The InsulMaxx 2000 machine was set up with 150 ft of internally corrugated hose with smooth 

transitions down to either a 2-in. ID nozzle or an 8-ft. long, 1-1⁄4-in. ID insertion tube. Test wall 

specimens were prepared using three installation methods:

• Bottom fill. The insertion tube was fed into the cavity, upward through one lower hole 

and drilled at approximately 24 in. above the bottom plate, until it was approximately 6 

in. from the top of the cavity. The cavity was filled with insulation and the tube was 

slowly withdrawn as the cavity filled, the material compressed, and the feed rate slowed.

This method most closely reflects the install method used for dense-packing cellulose. 

However, to achieve the lower densities recommended for fiberglass materials, the tube 

must be removed before the material flow comes to a complete stop and, unlike cellulose 

dense-packing, the tube is not pulled out and pushed part way back in. 

• Top fill. The insertion tube was fed into the cavity, downward through one top hole and

drilled at approximately 6 in. below the top plates, until it was approximately 6 in. from 

the bottom of the cavity. The cavity was filled with insulation and the tube was slowly 

withdrawn as the cavity filled, the material compressed, and the feed rate slowed.

• Two-inch nozzle. The cavity was filled with a 2-in. ID nozzle, using a “two-hole” or 

“three-hole” approach. The nozzle was introduced first through a lower hole and drilled 

at approximately 24 in. above the bottom plate. Insulation was filled first downward and 

then upward until it reached the level of an upper hole and drilled at approximately 24 in. 

below the top plates. The nozzle was then moved to the upper hole and insulation was 

filled upward until it reached the top of the cavity. When using the “three-hole” variation, 

the nozzle was inserted into the top hole and drilled approximately 6 in. below the top 

plates. Then material was added until the insulation was slightly packed.

The fiberglass insulation packaging and other documentation suggest a range of installation 

densities covering 1.0–2.6 pcf. BSC set out to prepare test wall specimens to address everything 

from median densities recommended for weatherization/retrofit/reinsulation applications (e.g., 

1.5–1.8 pcf) to the higher densities clearly intended for dense-pack (e.g., 2.2–2.6 pcf) and even 

into higher fiberglass dense-pack densities reported by some installers (e.g., 3.0 pcf). BSC
10 

intentionally avoided the lowest densities listed in “closed cavity” fill tables on packaging (e.g., 

1.0 to < 1.5 pcf), expecting that they would not provide any effective airflow resistance.

2.5 Other Experimental Methods

Other aspects of the test wall specimen preparation and airflow resistance testing followed the 

procedures summarized by Schumacher (2011). Installation techniques were refined and 

machine settings were established using the same density box method that was used for the 

previous cellulose tests. The installed material density was established using the same apparatus 

and methods as used for the cellulose tests. Finally, the background air leakage, short-path 

airflow test, and long-path airflow tests were conducted using the same equipment and methods 

as used for the cellulose tests.
11 

3 Results and Discussion

This section provides a summary of airflow resistance test results for select fiberglass and stone 

wool insulation materials. 

3.1 Test Program

Three loose-fill fiberglass insulation products were randomly selected from the five collected. 

Only one stone wool product was collected and tested. Only Building Science Laboratories staff 

know which manufacturers’ materials were used in the testing; the reporting is done using 

material codes (e.g., tests A1, A2, and A3 represent tests 1, 2, and 3 conducted using materials 

from manufacturer A). This reporting method was also used in the cellulose tests reported by 

Schumacher (2011). To avoid confusion with the previously completed cellulose test results, the 

three fiberglass materials tested were designated with letters O, P, and Q; the lone stone wool 

product was designated with letter R.

Test wall specimens were prepared to cover the range of densities identified on the packaging 

and in other documentation: roughly 1.8–2.5 pcf. 

3.2 General Airflow Test Results

Roughly 16 fiberglass test wall specimens and three stone wool test wall specimens were 

prepared and tested. 

3.2.1 Long- and Short-Path Airflow Test Results

Table 4 provides a summary of the test results for the four MFI products (three fiberglass and 

one stone wool) that were evaluated in this project. The highest and lowest measured flow rates 

are reported for each material along with the install density that was associated with each flow 

rate. For purposes of comparison, the table also includes the highest and lowest measured test 

results for the cellulose materials that were evaluated in 2011. Finally, the table includes the CFI 

benchmark flow rates recommended by Schumacher (2011).

When installed to higher densities (e.g., approximately 2.3–2.7 pcf) two of the three fiberglass

insulation materials (O and P) produced long-path airflow test results that were comparable with 

the cellulose insulation long-path airflow test results obtained by Schumacher in 2011. That 
12 

testing established long- and short-path airflow “benchmarks” of 0.33 and 1.0 cfm50/ft2, 

respectively, for historical dense-pack cellulose retrofits installed to 3.5 pcf. Again, when 

installed to higher densities (e.g., higher than approximately 2.3–2.7 pcf), two of the fiberglass

insulation materials (O and P) produced short-path airflow test results that were comparable with 

the cellulose insulation short-path airflow test results obtained in 2011. The measured 

performance of the fiberglass test wall specimens depended highly on the material tested and the 

installation method. These issues are discussed further in Section 3.3 of this report.

The long- and short-path airflow tests for the stone wool insulation resulted in airflow rates that 

were 1.5–2 times higher than the cellulose tests, despite the fact that the stone wool was installed 

at higher densities (e.g., 3.1–4.1 pcf). 

3.2.2 Flow Regime and Pressure Range

Dense-pack fiber insulation provides significant resistance to the flow of air. When the fibers 

completely fill a stud bay or other framed cavity, air must flow through the fiber matrix rather 

than through open voids. The resulting airflow should be laminar and, if data regression is 

performed assuming a power law relationship, the flow exponent (n) should be close to 1. 

Figure 3 plots the flow exponents calculated for the background leakage (blue squares in lower 

part of plot), long-flow path (red squares in upper part of plot) and short-flow path (green 

triangles in upper part of plot) tests for each of the mineral fiber test wall specimens. For all but 

one of the long- and short-flow path tests, the flow exponent is 0.9 or higher, suggesting that 

laminar flow is dominant and that the dense-pack fiber insulation largely eliminates open voids 

that would permit higher airflow rates. Figure 4 shows the same plot for the CFI tests that were 

conducted in 2011. The flow exponents for the long- and short-flow path tests of the cellulose 

test wall assemblies are slightly higher.

3.3 Influence of Material and Installation Method

This section discusses the individual airflow test results for the three fiberglass and one stone 

wool materials tested. The influences of material and installation method are addressed.

3.3.1 Material O

Density box specimens for Material O were first prepared using the bottom fill installation 

method. However, BSC was unable to produce acceptable specimens with densities lower than 

2.8–3.2 pcf. When lower test specimen densities were achieved using this method, the material 

was clearly not evenly distributed. For this reason, the team opted not to produce any full test 

wall specimens using the bottom fill method; but instead, sought to produce test wall specimens 

with densities of 1.8–2.5 pcf, using the top fill and 2-in. nozzle installation methods. 

The long-path airflow data for the six Material O tests are presented in Figure 5. Four of the 

Material O airflow tests were performed on samples installed using the top fill installation 

method (i.e., using the 8-ft insertion tube through the top installation hole). The remaining two 

airflow tests were performed on samples installed using just the 2-in. nozzle method (i.e., 

installed through the lower, upper, and top access holes on the front of the test apparatus). 
14 

Figure 5. Material O: long-path airflow rest results versus installed density and installation method 

The data presented in Figure 5 indicate that a wide range of airflow rates are possible for 

densities of 1.8–2.1 pcf. The airflow data from the insertion tube installations (O-1 to O-4, 

represented by the diamond-shaped markers) suggest a low correlation between airflow rate and 

density. Pockets of higher and lower density were visible in the test wall assemblies installed 

using the insertion tube method. The same observations were made when the CFI test specimens 

were prepared in 2011; however, density variations are believed to have less impact on airflow 

because the overall installed density of the CFI specimens was higher (3.5 pcf for CFI versus 

1.8–2.2 pcf for MFI. Lower airflow rates and tighter standard deviation might be achieved if MFI 

specimens were installed to higher densities using the insertion tube method (whether it is

bottom fill or top fill).

The lowest airflow rates for Material O were achieved using the 2-in. nozzle to fill the cavity 

through all three installation ports. 

The distribution of the insulation within the stud cavity was assessed by determining the 

difference between the long-path and short-path flow exponents. These flow exponents indicated 

that the 2-in. nozzle resulted in a more uniform density distribution. The average difference 

between the long- and short-path flow exponent values was 0.023 for the insertion tube and 

0.003 for the 2-in. nozzle. The flow exponent data for each test are presented in Figure 3. 

3.3.2 Material P

The long-path airflow data for the five Material P tests are presented in Figure 6. Four Material P 

test wall samples were prepared using the insertion tube methods (2 bottom fill and 2 top fill). 

The insulation for tests P-1 and P-2 (represented by the diamond-shaped markers) was installed 

using the top fill method while the bottom fill method was used for tests P-3 and P4 (represented 

by the square markers). The insulation for the P-5 test was installed using the 2-in. nozzle 

method and all three installation holes (lower, upper, and top) on the front of the test apparatus. 
15 

Figure 6. Material P: long-path airflow rest results versus installed density and installation method 

The data presented in Figure 6 indicate a well-defined correlation between airflow and installed

density for Material P. The regression analysis defines the relationship between airflow and 

density with a high degree of confidence for Material P. The slope of the regression line for the 

insertion tube installations was determined to be –1.1 cfm50∙ft/lb with an R2

 of 0.99. Because

there was a high degree of correlation between airflow and density, only one test was performed 

on Material P using the 2-in. nozzle installation, which yielded the lowest airflow performance 

for Material P. The air leakage test performed on the 2-in. nozzle installation determined the 

lowest measured long-path airflow rate (0.280 cfm50/ft2 at 2.03 pcf) of all the material data sets.

The difference between the long-path and short-path flow exponents varied between 0.001 and 

0.065 for the insertion tube installations (0.021 on average) and 0.022 for the 2-in. nozzle. The 

data in Figure 3 show that with the exception of P-1, the insertion tube installations produced 

uniform density distributions within the stud cavity. 

3.3.3 Material Q

Figure 7 presents the long-path airflow data for the five Material Q test wall specimens. Three of 

the Material Q airflow tests were performed on test wall specimens prepared using the 8-ft. 

insertion tube, one using the top fill method (Q-3) and two using the bottom fill method (Q-1, Q2). The remaining two airflow tests were performed on specimens installed using the 2 in. nozzle 

(Q-4, Q-5). The average installed density for Material Q tended to be higher than for other 

fiberglass products using similar installation methods. Overall, the average installed density was 

2.3 pcf for both the insertion tube and 2-in. nozzle methods. The lowest airflow rates were 

achieved using the 2-in. nozzle installation method. 
16 

Figure 7. Material Q: long-path airflow rest results versus installed density and installation method 

The data presented in Figure 7 indicate a well-defined correlation between airflow and installed 

density for Material Q when installed using the 2-in. nozzle; no correlation was observed in the 

insertion tube data. Better airflow performance might be observed if higher install densities had 

been sought using the insertion tube method. 

The regression analysis of the 2-in. nozzle data could not be defined with any degree of 

confidence because of the limited sample size (two); however, the slope of the regression line 

was determined to be –1.0 cfm50∙ft/lb, which compared well with the other data sets, as 

summarized in Table 4. 

The difference between the long- and short-path flow exponents varied between 0.013 and 0.027 

for the insertion tube installations and averaged 0.02 for the 2-in. nozzle. As shown by the flow 

exponents presented in Figure 3, the insulation density of the Material Q test cavities was 

moderately well distributed relative to the other Material types. The flow exponent data also 

indicate that the installation method had a limited effect on density distribution. 

3.3.4 Material R

The stone wool product designated Material R was not specifically designed for dense-pack 

retrofit applications. Through the density box calibration work, BSC found it impossible to move 

the fiber nodules through the 1.25-in. ID insertion tube; the hose constantly plugged. As a result, 

BSC was only able to prepare test wall specimens using the 2-in. nozzle method. Further, the 

team was unable to produce test wall specimens with densities lower than approximately 3.0 pcf. 

As a result, the average installed densities for the stone wool test walls were considerably higher 

than those produced using any of the fiberglass materials included in this study. 

Finally, the stone product contained a considerable amount of fine to coarse, non-fibrous 

material (i.e., “shot”) that BSC thought was too abrasive and likely to cause accelerated wear on 
17 

the fiber-moving equipment in dense-pack retrofit applications. The number of airflow tests 

performed on this sample was limited to three because this product is highly abrasive. 

Figure 8. Material R: long-path airflow rest results versus installed density and installation method 

Data from the airflow tests performed on this material demonstrated a consistent increase in 

airflow resistance with density; these data are presented in Figure 8. In light of the small data set, 

the slope of the regression line indicates that the airflow through this material changes at a rate of 

–0.7 cfm50∙ft/lb. This number compares well with the regression slopes observed in the fiberglass 

samples that were installed using the 2-in. nozzle; however, the densities are significantly higher. 

The lowest airflow rates for Material R were achieved with densities of 3.9 and 4.1 pcf. The 

corrected airflow rates associated with each of these densities were 0.74 and 0.67 cfm50/ft2

, 

respectively. 

These results also indicate that the resistance to airflow increases more slowly with density than 

what was observed in the fiberglass samples. This relationship may change if testing was 

completed using a more refined mineral wool product without the non-fibrous material (i.e., 

various sizes of solidified blobs or balls of molten rock, referred to as shot).

3.3.5 Installation Methods

Based on manufacturers’ instructions on packaging and in other documentation, three installation 

methods were tested. The installation experience and airflow test results collected under 

laboratory conditions suggest that the 2-in. nozzle installation method results in more even 

material distribution and lower long- and short-path airflow rates (i.e., higher airflow resistance) 

than either of the insertion tube methods (i.e., top or bottom). Also, many installers are familiar 

with nozzle installation methods because they are commonly used for installing cellulose fiber or 

fiberglass insulation in netted-and-blown installations (e.g., Blown-In Batt System). 

However, in netted-and-blown applications installers can easily see the “fill” of the cavity space 

through the netting and assess distribution and density by touch (i.e., by pushing on the netting). 

In netted-and-blown applications cavity spaces can be filled completely and to sufficient density 
18 

to minimize the potential for settling. In retrofit applications, loose-fill insulation materials are 

installed in existing cavities that are bounded by opaque, stiff materials (e.g., framing, sheathing, 

plaster, wall board) so the installer can neither see into the cavity space to assess fill nor touch 

the surface of the insulation to assess distribution and density. The insertion tube installation 

methods were (in part) developed to address these problems. 

Weatherization contractors and dense-pack installers are trained to understand different framing 

methods and to site-assess framing conditions to identify obstructions (e.g., blocking) that might 

prevent all cavities from being completely filled with insulation. Insertion tubes are graduated 

(i.e., typically marked at 1-ft intervals). Installers are taught to use the insertion tube to “probe” 

the bounds of cavities to identify obstructions as they are installing. The insertion tube is pushed 

to the furthest reaches of the cavity to confirm that dimensions are as expected. The insertion 

tube is withdrawn only a few inches before starting to fill the cavity. This ensures that insulation 

is delivered to the far end of the cavity without catching on partial obstructions and creating an 

uninsulated space or pocket, as is possible when using a nozzle installation method. 

Some installers use the nozzle installation method for dense-pack retrofit applications. This 

testing supports the belief that good airflow resistance can be achieved using the nozzle 

installation method. However, given the realities discussed in the previous paragraph, insertion 

tube installation methods should be considered a best practice for retrofit applications. If the only 

goal of an insulation retrofit is to fill cavities with insulation, insertion tube installation methods 

should be recommended and lower density installs can be accepted (assuming density is 

sufficient to prevent settling). However, if the goals are to fill cavities with insulation and to 

reduce airflow in and through assemblies, insertion tube installation methods should be accepted 

and install densities should be established to provide sufficient airflow resistance.

This research sought to evaluate test wall specimens installed to the manufacturer-recommended 

densities, using the methods identified in the various manufacturers’ literature. If the goal is to 

provide comparable airflow resistance to the benchmarks for historical dense-pack cellulose 

retrofits (i.e., long-path airflow of 0.33 cfm50/ft2

 and short-path airflow of 1.0 cfm50/ft2), further 

testing is necessary to establish recommended install densities for insertion tube installation 

methods. 
19 

4 Conclusions and Recommendations

This report documents airflow resistance test results for dense-pack retrofit applications using 

MFI materials (i.e., glass fiber and stone wool). The test results are compared to previous airflow 

resistance tests for dense-pack retrofit applications using 10 different CFI materials.

Loose-fill MFI products (i.e., fiberglass and stone wool) have different fiber structures than CFI

and, as a result, mineral fiber products are expected to require different installation densities than 

cellulose insulation products. However, the recommended installation methods and densities for 

fiberglass products are unclear. Only one of the five fiberglass materials collected had consistent 

instructions and recommended install densities between the packaging, dense-pack 

documentation and weatherization/retrofit documentation. In all other cases, the installer is faced 

with a range of instructions and install densities to work toward. Greater clarity and consistency 

are needed in the installation instructions and recommended install densities for fiberglass

products used in dense-pack retrofit applications.

Airflow resistance varied significantly between loose-fill fiberglass products, even though all the 

compared products are marketed and supported for use in dense-pack retrofit applications. When 

these fiberglass products were installed at approximately 2.2 pcf, the variance was 0.33–1.73 

cfm50/ft2

. The distribution of the installed material, and thus the airflow resistance, also depend 

on installation method. In this testing, BSC sought to qualitatively and quantitatively assess the 

three installation methods identified in the survey of instructions from packaging and information from dense-pack and weatherization/retrofit documentation: (1) bottom fill, using an 

insertion tube installed up through a hole at approximately 24 in. above the bottom plate; (2) top 

fill, using an insertion tube installed down through a hole at approximately 6 in. below the top 

plates; and (3) 2-in. nozzle, installed through two or three holes (e.g., at holes approximately 24 

in., 72 in., and 90 in. above the bottom plate). 

Two of the three loose-fill fiberglass products tested (installed at approximately 2.3 pcf) 

produced long-path flow rates of 0.28 and 0.42 cfm50/ft2

 and short-path airflow rates of 0.76 and 

1.1 cfm50/ft2

. These are comparable to the cellulose dense-pack retrofits benchmarks of 0.33 and 

1.0 cfm50/ft2

 for the long- and short-path airflow rates, respectively (CFI installed at 3.5 pcf as 

required by BPI). However, the fiberglass test walls were prepared using the 2-in. nozzle 

installation method, not the insertion tube methods recommended as best practice for retrofit 

applications. These results indicate that there is potential for dense-pack applications of MFI, but 

that more work needs to be done to develop appropriate standards for real-world installation 

needs. In particular, further testing should be conducted to establish recommended install 

densities for insertion tube installation methods. 

Finally, none of the stone wool manufacturers support dense-pack retrofit applications using 

their products. Only one loose-fill stone wool insulation product was collected for testing. The 

stone wool fibers and nodules were too large to successfully install using either of the insertion 

tube techniques. Loose-fill stone wool is not recommended for dense-pack retrofit applications.

Dense Packing

Historically, cellulose has been promoted as the only choice for 

dense pack applications. However, CertainTeed InsulSafe SP 

and OPTIMA loose-fill fiber glass insulation provides the same 

reductions in air permeance* as cellulose while delivering a 

number of other significant benefits.

* BPI-102, “Standard for Air Resistance of Thermal Insulation Used in Retrofit Cavity Applications — Material 

Specification,” is BPI’s approved technical standard for insulation used in air sealing, and requires that such 

products limit maximum air permeance to 3.5 cfm/ft2

 (as measured using ASTM C522). InsulSafe SP achieves this 

permeance rating at a density of 2.2 lbs/ft3

 and OPTIMA at 2.5 lbs/ft3. This compares to 3.5 lbs/ft3 for cellulose.

InsulSafe® SP and OPTIMA® offer many 

additional benefits when compared to cellulose

Preparatory Work:

s #HECKSTRUCTURALSOUNDNESSOFWALLFACINGS&ACINGS

can be damaged by blowing pressure if they are weak 

or loosely attached.

s Check for symptoms of moisture problems such as blistering paint, mildew, staining, odor, etc., 

on interior or exterior wall surfaces. Any such problem should be brought to the owner’s attention.

s Check for fire stops. If present, they will be at mid-height and holes must be drilled above 

and below these obstructions.

s Note and mark all areas that must not be drilled (location of wall ducts, vents, recessed cabinets, 

service panels, etc.).

s Make certain all wall openings through which insulation could enter the house are sealed.

Method(s): Two basic methods are recommended for insulating sidewalls with OPTIMA: 

the directional nozzle method and the insert tube method.

Method 1 – Directional Nozzle:

s Drill two 11⁄2" or 13⁄4" diameter holes into each stud cavity, one hole 3' up from the base 

of the wall and one hole 2' down from the top plates. Don’t blow more than 3' down or 2' up 

from any hole.

s Drill holes into cavities below windows and into cavities above windows when there 

is no solid header.

s Use 200' of internally corrugated hose stepped down in diameter to a 11⁄4" to 11⁄2" I.D. nozzle 

(50' of 3" to 100' of 21⁄2" to 50' of 2" hose). (The nozzle can be fabricated from a metal electrical 

conduit elbow.)

INTRODUCTION

CWI Plus is a premium fiberglass insulation wall injection system designed 

primarily for residential retrofit applications. The CWI Plus system utilizes 

virgin white no formaldehyde added loose-fill fiberglass insulation injected 

into existing residential studwall cavities that are either empty or partially 

filled with old insulation. 

The CWI Plus system process is very simple: Fill the existing cavities with 

insulation to help bring the home in line with current residential energy 

codes. There is no product waste. Energy savings & total home comfort are 

benefits of installing CWI Plus.

In addition, your present loose-fill insulation blowing machine can be 

converted to the CWI Plus system with relative ease at a nominal cost. This 

conversion is primarily a hose configuration. Your machine can still be used 

for blowing attics. 

This Operating Manual will describe all the aspects of the CWI Plus system, 

from the process and equipment to installation and troubleshooting. A list 

of approved CWI Plus insulation blowing machines & system components 

is contained in the EQUIPMENT section.

Regarding the use of non-electric machines (machines powered by gas, diesel, or PTO), the use of a mechanical blowing machine is not recommended for this type of retrofit wall insulation project. Appropriate 

equipment must be designed for fiberglass and have an effective shredding sections, a controlled feed section and sufficient air volume to achieve the desired results. Air blowers with no pressure cut-off can create 

positive displacement of air. Pressure buildup in the wall cavity may occur causing serious problems.

EQUIPMENT

The CWI Plus System equipment consists of the following components:

 

 1 ea. Fiberglass insulation blowing machine

 1 ea. 2” => 1” CWI Plus Reducing Nozzle

 150 ft. Ideal spray hose configuration: 3” => 2.5” => 2” (50ft of ea.)

BLOWING / INSTALLATION

Closed cavity applications can be difficult to judge material usage during 

installation since fiberglass is compression filled in the cavity. 

It is recommended that material usage be monitored as the job progresses, so that the proper number of bags is being installed.

Material feed rate should be approximately 1 bag of CWI Plus every 5 min.

“DENSE-PACK” APPLICATION 

JM Spider insulation offers many big advantages over cellulose in drill-and-fill applications. Incredibly easy 

to install, it’s convenient and saves time, while offering superior thermal and acoustical performance.

JM Spider insulation also provides up to 30% better airflow resistance than cellulose when installed at

recommended densities for site-built construction. Our unique design enables the fibers to more effectively 

fill tight spaces around pipes, wires and electrical boxes. For example, JM Spider insulation will fill 2x4 

cavities up to an impressive R-15 thermal rating and 2x6 cavities up to R-24. In addition, since fiber glass is 

naturally mold resistant, it does not encourage the growth of mold or mildew.

WHY JM SPIDER? 

Small Fiber Diameter:

• Superior thermal and acoustical performance

• Provides higher airflow resistance vs. cellulose

Small Nodule Size:

• Allows insulation to easily flow around obstacles within a wall cavity

• Allows for complete and uniform cavity fill

• Allows for use of small-diameter application hoses and mortar tools

• Minimizes potential for equipment plugging

• Won’t lose R-value due to natural convection

FINER FIBER = BETTER AIRFLOW RESISTANCE, BETTER THERMAL PERFORMANCE

Fine-diameter JM Spider fiber creates a tortuous path for heat and airflow, resulting in high thermal and airflow resistance. JM Spider fiber is also very 

effective at scattering and absorbing IR radiation, which further improves R-value. Coarse-fiber cellulose has more direct airflow passages and poorer IR

blocking capability, which results in less resistance to heat and airflow.

PERFORMANCE ADVANTAGES

t Improves indoor air quality – because it’s 

made without formaldehyde.

t Energy efficient – provides superior resistance 

to heat transfer with R-values up to R-15 in a 

2x4 cavity.

t Completely fills the cavity and does not 

settle–the small nodules of fiber glass are 

resilient and do not deteriorate or lose 

performance with time. 

t Controls sound – reduces transmission of 

sound through exterior and interior walls 

and floor/ceiling assemblies. See the 

JM Spider insulation Acoustical Performance 

Advantages sheet (BID-0080) for details.

t Easy to install – installs at a rate per cavity 

similar to dense-packed cellulose with 

significantly less plugging and less dust. 

t Mold and mildew resistant – fiber glass is 

naturally mold resistant. 

t Fire resistant and noncombustible

t Noncorrosive – does not accelerate corrosion 

of pipes, wiring or metal studs.

t Durable – will not rot, mildew or otherwise 

deteriorate. JM Spider insulation will not 

hold moisture or permanently lose R-value.

t Small nodule or tuft size allows the product to 

easily flow around obstacles, such as wiring, 

and through small-diameter mortar tools.

t Higher installed R-value per inch vs. cellulose 

(typically more than 20 percent higher R value 

up to R-4.3 per inch).

t Works with most types of blowing machines 

designed to process fiber glass insulation.

t Provides significantly higher airflow 

resistance than cellulose (per ASTM C522 

measurements).

JM FORMALDEHYDE-FREETM FIBER GLASS INSULATION

JM Formaldehyde-freeTM fiber glass building insulation offers the thermal and acoustical performance 

you expect from fiber glass—and it improves indoor air quality because it’s made without formaldehyde. 

Why is that important? Because reducing overall formaldehyde levels in the home creates a healthier 

living environment, and choosing JM Formaldehyde-freeTM insulation is one way of achieving that goal. 

JM offers a complete line of Formaldehyde-freeTM fiber glass building insulation. Visit specJM.com or 

JMhomeowner.com for more information.

PRODUCT DESCRIPTION

JM Spider insulation offers many big advantages over cellulose in drill-and-fill applications. Incredibly 

easy to install, it’s convenient and saves time, while offering superior thermal and acoustical performance. 

JM Spider insulation also provides up to 30 percent better airflow resistance than cellulose when installed 

at recommended densities for site-built construction. Our unique design enables the fibers to more 

effectively fill tight spaces around pipes, wires and electrical boxes. For example, JM Spider insulation 

will fill 2x4 cavities up to an impressive R-15 thermal rating and 2x6 cavities up to R-24. In addition, 

because fiber glass is naturally mold resistant, it does not encourage the growth of mold or mildew.

t1MBTUFSMBUI  t5JMFNBTPOSZ

JM Spider insulation also works for weatherization of other exterior cavities such as bonus room floors, 

cantilevered areas and cathedral ceilings that do not require venting. For these closed cavities, follow 

the same installation procedures as walls. For open cavities such as floors over crawl spaces, dense pack 

JM Spider fiber behind netting. (For crawl space floors, be sure to consult the local code requirements 

for vapor retarders and contact BIBCA if you need information and training on dense packing JM Spider 

insulation behind netting.) It’s also a good idea to install JM Spider insulation in interior walls that 

contain supply plumbing and PVC waste drains to significantly reduce unwanted noise. Contact your 

local JM sales representative for availability of JM Spider insulation. Visit specJM.com for additional 

information, including information on installing.

RECOMMENDED STORAGE AND TRANSPORT

Store insulation indoors. Keep insulation clean and dry at all times. When transporting, cover completely 

with a waterproof tarpaulin as necessary.

What you should know about R-Values. 

The chart shows the R-value of this insulation. “R” 

means resistance to heat flow. The higher the R-value, 

the greater the insulating power. Compare insulation 

R-values before you buy. There are other factors to 

consider. The amount of insulation you need depends 

mainly on the climate you live in. Also, your fuel 

savings from insulation will depend upon the climate, 

the type and size of your house, the amount of insulation already in your house, and your fuel use patterns 

and family size. If you buy too much insulation, it will 

cost you more than what you’ll save on fuel. To get the 

marked R-value, it is essential that this insulation be 

installed properly.

Sidewall Installation: EcoFillTM Wx Blow-in-Blanket 

System has been designed to be dense-packed to a 

density of 2.2 PCF in sidewalls of existing structures 

and should be installed by professionals.

Note: The chemical and physical properties of EcoFillTM

Wx Fiber Glass Blowing Insulation represent average 

values determined in accordance with accepted test 

methods. The data is subject to normal manufacturing 

and testing variations. The data is supplied as a 

technical service and is subject to change without 

notice. 

Check with your Knauf Insulation sales representative 

to ensure information is current.

This is Fiber Glass Blowing Insulation. Read this before you buy.

Bag Net Weight - Nominal 30 lbs., Minimum 29 lbs.

Coverage and installation data were determined using a Volu-Matic® II blowing machine in 3rd gear with 13" gate opening, 2.0 psi air pressure, 150' 

of 3" diameter internally-corrugated hose.

* “R” means resistance to heat fl ow. The higher the R-value, the greater the insulating power. To get the marked R-value, it is essential that this 

 insulation be installed properly. If you do it yourself, get instructions and follow them carefully. Instructions do not come with this package.

**Based on a third party 2-year settling study, the predicted settlement over a 20-year period would be 1 percent or less. This amount of settling is 

 thermally insignifi cant. Therefore, the installed and settled thicknesses are effectively the same.

A NEW STANDARD FOR INSULATION 

& AIR INFILTRATION.

The Ultimate In Air Infiltration and Thermal Performance.

When it comes to choosing insulation for weatherization projects in existing homes, many factors – 

including thermal performance and air infi ltration – come into consideration. Many people assume 

cellulose is the best choice. But there is a better choice – Owens CorningTM PROPINK® L77 PINK 

FiberglasTM Loosefi ll Insulation delivers exceptional performance for air-infi ltration control and 

thermal protection compared to cellulose insulation.

New Formulation. New Dense-Packing Capabilities. New Standard In Performance.

Owens CorningTM PINK Fiberglas Loosefi ll Insulation has been 

reformulated to make it more effective for use in wall applications.

 • Easily installed in walls and improved 

 nesting for compaction

 • Can now be “dense packed” into walls at an 

 installed density of up to 2.50 pounds per cubic foot*

 • Achieves an airfl ow reduction equal to cellulose,

 while providing R-value greater than cellulose**

Easy Installation.

• Easily fl ows around obstacles within a wall cavity, allowing for complete and uniform cavity fi ll, 

 especially for “drill and fi ll” applications

• Dense packing of PINK Fiberglas Loosefi ll Insulation can be achieved by professional installers 

 using most machines that are currently used to blow either fi berglass or cellulose insulation into 

 existing wall cavities

Most tested. Most trusted.

At Owens Corning, we apply over 70 years of building science expertise and rigorous testing to every 

product we make. Our PINK Fiberglas Loosefi ll Insulation products won’t settle or deteriorate with 

age, so there’s no danger of losing R-value over time. It’s noncombustible, meeting all model building 

codes for non combustibility. It won’t absorb moisture or support mold growth.‡ Simply put, it’s safe 

and one of the most effective insulation products you can use in a home.

* Ensure that the wall system can withstand the additional forces before dense packing any insulation material.

** R-value means resistance to heat fl ow. The higher the R-value, the greater the insulating power. Ask your seller for the fact sheet on 

 R-values. To get the marked R-value, it is essential that insulation be installed properly.

† PROPINK® L77 PINK FiberglasTM Loosefi ll Insulation was tested using the Volumatic II. Results may vary based on equipment used.

‡ As manufactured, fi ber glass insulation is resistant to mold growth (tested per ASTM C 1338). However, mold growth can occur on building 

 materials, including insulation, when it becomes contaminated with organic material and when water is present. To avoid mold growth on 

 fi ber glass insulation, remove any water that has accumulated and correct or repair the source of that water as soon as possible. Insulation 

 that has become wet should be inspected for evidence of residual moisture and contamination, and any insulation that is contaminated 

 should be promptly removed and replaced.

PROPINK® L77 PINK® FiberglasTM

Unbonded Loosefi ll Insulation

This fact sheet contains important details about Owens Corning’sTM

PROPINK® L77 PINK® FiberglasTM Unbonded Loosefi ll Insulation. Read 

it carefully. 

Owens Corning will accept no responsibility when the product is 

not installed in accordance with the product label. Stated R-value is 

provided by installing the required number of bags at a thickness not 

less than the label minimum thickness. Installation of the required 

number of bags may yield more than the specifi ed minimum thickness. 

Failure by the installer to provide both the required bags and at least 

the minimum thickness will result in lower insulation R-value. 

Read This Before You Buy

What you should know 

about R-Values:

The chart shows the R-values 

of this insulation. “R” means 

resistance to heat fl ow. 

The higher the R-value, the 

greater the insulating power. 

Compare insulation R-values 

before you buy.

There are other factors to 

consider. The amount of 

insulation you need depends 

mainly on the climate you 

live in. Also, your fuel savings 

from insulation will depend 

on the climate, the type and 

size of house, the amount 

of insulation already in your 

house, and your fuel-use 

patterns and family size. If you 

buy too much insulation, it will 

cost you more than what you’ll 

save on fuel.

To get the marked R-value, it 

is essential that this insulation 

be installed properly.

Retrofi tting Existing Sidewalls with GreenFiber Insulation

Contractor Work Instructions

90
Before Installation 

Retrofi tting any part of a home’s envelope will cause changes 

in air, heat and moisture fl ow. Contractors must understand 

how this installation will impact the house, i.e., ventilation and 

combustion air requirements. Examine both the inside and 

outside of a home to determine areas that are inappropriate 

for installation. For example:

• Do not insulate any home that has active knob and 

tube wiring. 

• Where moisture related problems are evident, the source 

of the problems must be determined and corrected before 

proceeding. 

• Do not install insulation in stud runs where heat-producing 

 devices such as an unprotected chimney, a fi replace, etc. 

might cause severe overheating.

• Building assembly details such as balloon framing, fi re 

blocking, pocket door connections, dry wall gaps or other 

leak points must be taken into consideration when blowing 

GreenFiber Insulation into a house. 

• GreenFiber’s Material Data Safety Sheet (MSDS) requires the 

use of safety eyewear when installing this product. The insulation contractor is responsible for managing housekeeping 

and engineering controls below nuisance dust levels. Follow 

all OSHA guidelines for safety requirements including 29 CFR 

1926.501 Duty to Have Fall Protection. Various other local, 

state and federal rules and guidelines may apply.

Application

There are two basic techniques (Two-Hole or Double-Blow 

Method and One-Hole Tube Fill Method) used to fi ll existing, 

enclosed sidewall cavities. These techniques can be 

performed from either the exterior or interior of a home.

Installation through the interior wall is very diffi cult and is not 

detailed here. While it can be done, there is a wide range of 

other considerations related to someone currently occupying 

the home that present challenges to interior wall installation.

Required Equipment:

• Insulation blowing machine capable of at least 

 2.9 psi at the end of the hose

• Not all insulation blowing machines meet this requirement; please check with GreenFiber Customer Service – 

800.228.0024 – for verifi cation.

• 1⁄4-inch fi berglass rod

• Hose clamps

• Utility knife

• Filter (such as sponge)

• Wood, plastic, cork or Styrofoam plugs

• Drill and a 2 to 3-inch hole saw / Forstner bit

• 50-100 ft. of 3-6 inch inside diameter ribbed hose

• 1 to 11⁄2 -inch reducer nozzle

• 12 ft., 1 1/8 to 1 1⁄4-inch inside diameter tube 

 • Best practice: 1 1/8 to 1 1⁄4 - inch tube will match 

sturdiness of a thin wall irrigation hose

• Note: When connecting hoses, a gradual reduction from the 

outlet to the 1 1/8 - 1 1⁄4 inch hose will yield the best results.

One-Hole Tube Fill Method

The one-hole tube fi ll method is recommended by state 

Weatherization Assistance Programs for the retrofi t of sidewalls, 

and is the GreenFiber preferred method for retrofi tting existing 

sidewalls. When performing Weatherization Assistance 

Program work, follow the instructions below.

Density Check

GreenFiber requires the use of either a core sampling method 

or a bag count and volume method to assess the installed 

density of its products when using the Dry Dense-Pack 

method. GreenFiber specifi cations call for a minimum density 

of 3.5 pcf (pounds per cubic foot) in 2x4 and 2x6 cavities. 

These two methods 

are described below.

Retrofi tting Existing Sidewalls with GreenFiber Insulation – Contractor Work Instructions

The following instructions are for contractors for the 

purpose of retrofi tting existing sidewalls with GreenFiber 

Insulation. These instructions are designed for use with 

GreenFiber’s INS770LD, INS765LD, INS745, INS735, or 

INS515LD products for installation in sidewall cavities. 

Follow the sidewall coverage charts on the bags to assure 

that the proper amount of insulation is installed.

Instructions for One-Hole Tube Fill Method

1. Remove a section of exterior siding and drill a single 2 

1⁄2-inch diameter hole through the sheathing approximately 

one foot from the bottom plate of the wall.

2. Using a hose clamp, attach the 1 to 11⁄2 - inch reducer 

nozzle to the insulation blowing machine hose. 

3. Using a hose clamp, attach the 12 ft., 1 1/8 or 1 1⁄4 - inch 

inside diameter tube to the end of the reducer nozzle. 

4. Using the utility knife, cut the end of tube on a diagonal to 

facilitate snaking behind wiring and plumbing. 

5. Suggested beginning settings for Insulation blowing 

machine:

 a. Material gate set to 25% of total opening.

 b. Air setting at 60% of capacity.

NOTE: These settings are given as a starting point. Adjustment 

will be needed based on machine type and condition. 

6. Insert cut end of the tube through the fi lter into the 2 

1⁄2-inch drilled hole and feed to within 6-inches of the top of 

the stud cavity. Note any fi re stops or other obstructions. 

Drill additional holes as needed if obstructions are present.

7. Turn on insulation blowing machine (Hold tube in place 

6-inches from top). As material begins to fl ow, the cavity 

will fi ll bottom to top. 

8. When you feel resistance from the tube, the cavity is full 

- DO NOT STOP BLOWING. You will now begin the Dry 

Dense-Pack Procedure. Dry Dense-Packing is required 

to achieve the minimum requirement of 3.5 pcf in wall 

cavities.

9. Dry Dense-Packing means you will begin compressing the 

material in the cavity and excess air will be forced out the 

entry hole. Move tube up and down 4 inches until material 

threatens to plug tube. Then retract the tube 8-10 inches.

10. Repeat Dry Dense-Packing procedures until within 6 

inches of the entry hole.

11. When within 6 inches of entry hole quickly redirect tube 

downward to Dry Dense-Pack bottom of cavity.

12. Repeat Dry Dense-Packing procedures in bottom of cavity. 

13. Retract tube to entry hole, jab forward 3 to 4 times to 

fi nish Dry Dense-Packing entry area.

14. Turn insulation blowing machine off. Keep tube in hole for 

3 to 4 seconds before fully removing from cavity. 

WI-6.19-10 Rev I 07/13

92
Two-Hole or Double-Blow Method

The two-hole or double-blow method is the most frequently 

used procedure for installing loose-fi ll insulation in sidewalls 

of existing homes. This method allows air pressure to escape 

from the upper hole while fi lling the cavity from the lower hole. 

Instructions for Two-Hole or Double-Blow

1. Remove exterior siding to drill holes wherever possible to 

avoid potential damage/appearance defects to the exterior 

of the house. 

2. Drill a hole between two studs approximately 2.5 to 3 

feet up from the bottom plate. Drill a second hole 

approximately one foot below the top plate in the same 

stud run. On a multi-story home, repeat this process on 

each fl oor.

3. Drill holes approximately 2-inches in diameter through 

sheathing if siding is removed. A 2-inch diameter hole 

enables directional application.

4. Using a hose clamp, attach a 1-inch reducer nozzle to the 

insulation blowing machine hose.

5. Adjust air pressure to accommodate wall installation and 

nozzle size. This will ensure proper compacting of 

insulation and prevent settling in the cavity.

 a. Air pressure adjustment will vary depending on 

machine type and condition. More air pressure is 

required for sidewall installation than attic installation. 

Contact the machine manufacturer for the correct 

settings. 

6. Insert the nozzle into the bottom hole fi rst and turn on the 

blowing machine. An increase in back pressure causes 

the blower to strain and alerts the installer that the cavity is 

fi lled and ready for compaction. 

7. When material is no longer fl owing through the hose, 

visually ensure the cavity is completely fi lled. Move the 

nozzle to the next hole in the stud cavity. Continue this 

process until each stud run in the wall is fi lled. 

8. Fill the holes using wood, plastic, cork or Styrofoam plugs. 

Replace the siding if removed. If siding was not removed, 

use exterior-grade spackle to cover the plugs.

Contact your GreenFiber technical representative if 

you have questions regarding coverage, equipment or 

application at 800.228.0024.
