3.0 DESCRIPTIONREPORT HOLDER:

3.1.1 Aggre-flex Class PB EIFS: The Aggre-flex EIFS is a
nonload-bearing exterior insulation and finish system (EIFS)
applied to exterior walls. The components of the system arefield-installed on substrates of masonry, concrete, gypsum
sheathing, and wood-based sheathing. The system is a fourcomponent wall system consisting of molded expanded
polystyrene (EPS) foam plastic insulation boards, fiberglass
reinforcing mesh, base coat and finish coat. The insulation
board can be adhesively or mechanically applied, depending
upon the substrate. Figure 1 shows application details.

This section applies to Types I, II, III and IV construction underthe IBC; Types 1, 2, 3 and 4 under the BNBC; Types I, II, III,IV and V under the SBC; and Types I, II, III and IV under the
UBC. When the Aggre-flexPB EIF Systems are installed as anexterior wall cladding on buildings required to be ofnoncombustible construction, the wall assembly must comply
with the following:
4.4.1 Interior Surface: One layer of 5/8-inch thick (15.9 mm),
Type X gypsum wallboard, installed horizontally in accordancewith Chapter 25 of the applicable code, with 15/8-inch-long(41.3 mm) drywall screws spaced 8 inches (203 mm) on
center.
4.4.2 Steel Studs: Minimum No. 18 gage [0.0486 inch
(1.234 mm) base-metal thickness], 4-inch-deep (102 mm), Cshaped steel studs. Studs must be spaced a maximum of 16
inches (406 mm) on center, without insulation in the studcavity.
4.4.3 Exterior Surface: One layer of minimum 1/2-inch-thick(12.7 mm) gypsum sheathing complying with ASTM C 79 must

The Aggre-flex PB EIFS must not be installed onframed walls of Type V construction, Group R1, R2, R3
or R4 Occupancies, under the IBC; framed walls of TypeV construction, Group R1 or R3 Occupancies, under the
UBC; framed walls of Type 5 construction, Group R-1,
R-2, R-3 or R-4 Occupancies, under the BNBC; framedwalls of Type VI construction, Group R1 and R2

Page 6 of 22
Occupancies, under the SBC; or under the IRC. An
exception is masonry or concrete walls of Type V
construction under the IBC, Type V construction under
the UBC, Type 5 construction under the BNBC, andType VI construction under the SBC.
5.8

5.9

Termination of the systems must not be less than 6
inches (152 mm) above finished grade, under Section
2304.1.4 of the SBC and Section R320.4 of the IRC andSection 2603.8 of the IBC.
Installation cards, similar to those shown in Figures 5, 6
and 7, must be completed by the applicators andpresented to the code official at the completion of eachproject.

7.0 IDENTIFICATION
Each container or package of material used as part of the
Master Wall EIF Systems covered by this report must belabeled with the Master Wall Inc., name and/or trademark, andaddress and telephone number; the product trade name; andthe evaluation report number (ESR-1181).
Master Wall EPS insulation boards are delivered in sealed
polyethylene bags bearing the word “Master Wall,” the plant
identification number of the block molder, the name of theinspection agency [RADCO (AA-650)], the evaluation report
number (ESR-1181). In addition, one board in each bag mustbear these same markings on each face.
Other foam plastic boards must be identified in accordancewith their respective evaluation reports. When used on walls
required to be of noncombustible construction, EPS foam
plastic boards must also be identified along the edge of eachpiece, and on both faces of at least one board from eachpackaged bundle, with the following information:• The Aggre-flex Class PB name and the evaluation report
number (ESR-1181).
• The name and evaluation report number of the insulation
board molder.
• The name of the inspection agency, as indicated in theevaluation report for the foam plastic.
