. 12650-1 C09Confidential Report To V .O .C . Emissions Profiling ofa Polyurethane FoamSample 1 PRODUCT DESCRIPTION TYPE OF MATERIAL: The product tested was a spray-applied polyurethane thermal insulation product identified as The two components of this product were labeled as ; A-side: #A-100-4; and Bside: #B-500-F ; lot 9264. The creation dates for the components were notated as 24 August, 2009 and 05 August, 2009, respectively. SAMPLE RECEIVED

: The sample was created on 26 August, 2009 at the facility in nder the supervision of of Exova / Bodycote Testing Group. The sample was in turn sealed air-tight and was transported via overnight courier to the SRC Building Performance laboratory in Saskatoon, Saskatchewan. 2 TEST OBJECTIVE The testing objective was to identify and quantify volatile organic compound (VOC) emissions fromthe spray-applied polyurethane thermal insulation

using Procedure 'B' of the Underwriters Laboratories of Canada (ULC) CAN/ULC-S774-09 Standard . 3 METHODOLOGY 3.1 Storage and Pre-conditioning of Product The two drums containing components A and B of the spray-applied polyurethane foam were stored at the facility in Boisbriand at 24.0°C (75°F) and 65% relative humidity for periods of; 2 days tor the A-side component and 21 days for the Bside component, prior to testing. It was advised that oolicy limits storage duration to 6 months prior to use of the product, per the Exova Witness Report, refer to Appendix 8 - Witness Report . 3.2 Preparation of Test Chambers Prior to receiving the insulation sample and following the assembly of the test chambers and associated equipment, all systems were run-up to test conditions and allowed to stabilize for a period in excess of 72 hours . In preparation of the test, background measurements were taken on each chamber 04 August, 2009 to ensure contamination levels did not exceed the maximumallowable background level (i .e. 2%of the permissible indoor air concentration limit for any compounds identified) .

Sample 3.3 Mixing and Spraying the Polyurethane Foam Components A and B, as identified in Section 1, were mixed and sprayed at approximatelv 11 :10am local time, Wednesday, 26August, 2009 at the a qualified insulation sprayer in accoraance with CAN/ULC-S774-09. The spraying procedure was independently witnessed by Mr. David Rousseau of Exova / Bodycote Testing Group. 3.4 Preparation of the Foam Test Panel The polyurethane thermal insulation test panel was produced using a commercially available, fixed ratio, positive displacement pump. This unit is specifically designed for the application of sprayed polyurethane thermal insulation. See Section 5.1 . In accordance with the testing standard, the product was sprayed upon a polyethylene board covered with aluminumfoil to create a panel . The sample piece was cut fromthe centre of the panel at a location where the foil separated the sample fromthe PE board. The sample was then sealed air-tight in a new Tedlar bag and placed in a sealed case for immediate transport to SRCfacilities . 3.5 Headspace Analysis A test specimen was cut fromthe sample piece on 27 August, 2009 at SRC, Saskatoon, and installed in the headspace chamber (0.33 litre volume) . The chamber was then sealed and maintained at 40°C (104°F) for 24 hours. On 28August, 2009 an air sample was drawn fromthe headspace chamber. The headspace analysis is useful when concentration levels of compounds in the 1 and 12 hour tests are too low for identification by mass spectral library . The headspace apparatus often generates higher concentrations of compounds that volatilize quickly. In most situations, the headspace analysis is not required since the concentrations are of sufficient strength during the regular chamber tests . 3.6 Dynamic Chamber Test Sample Preparation On 27 August, 2009 the sample was removed fromits air-tight packaging and was cut into appropriately sized and shaped pieces for introduction into the dynamic chamber . The specimens were freshly cut on all six sides. The dynamic-chamber portions of the sample were cut into two (2) thicknesses of 25mm and were installed into stainless steel specimen holders. The exposed surface area provided a chamber loading ratio of 0.5 square metres per cubic metre (M2/M3)

. One specimen was introduced to the 51 .2 litre stainless steel dynamic chamber (specimen #1) while the other specimen (specimen #2) was retained in an airtight glass 2 SRC Publication No. 12650-1C09Confidential Report To V .O.C . Emissions Profiling of a Polyurethane Foam

Sample vessel . The headspace-chamber portion of the sample (specimen #3 - refer to Section 3.5) was introduced to the headspace chamber to occupy approximately 50%of the 0.33 litre volume. The introduction of the sample to the dynamic chamber occurred at 09:08amlocal time; 23 hours and 58 minutes after spraying . This is in accordance with the testing standard's requirement for the test to commence within 24 hours of the sample's production (CAN/ULC-S774-09; Section 6.1 .2) . 3.7 Dynamic Chamber Analysis (Procedure B) The dynamic test chamber was operated in an environmental enclosure with the air sampling apparatus mounted externally. Air samples to determine chamber emission concentrations were taken at the specified time intervals as prescribed in the CAN/ULC Standard, CAN/ULC-S774-09; air samples were drawn at 1, 12, 24 and 48 hours and days 4, 7, 14 and 30 (Refer to Section 7.3) . The air samples were then analyzed as described in Section 4 and Appendix A - Analytical Method. 4 ANALYTICAL TECHNIQUES CarbotrapTM400 absorbent tubes, in conjunction with gas chromatograph / mass selective detector (GC/MSD) analysis, were utilized for all air sampling sessions to identify and quantify volatile organic compound emissions fromthe sample. All air sampling flowrates and times were strictly observed, as defined within the testing standard, to ensure the product's emissions profile was accurately captured and related. 4.1 CarbotrapTMSamples The Carbotrap" M400 adsorbent tubes were thermally desorbed using a Supelco thermal desorption unit at 300°C (572°F) for three minutes. Any volatilized compounds are directed into the GC/MSD for compound identification and quantitation . The quantitation of the compounds may be achieved by several protocols: 1) using toluene response factor for semi-quantitative estimate of compound concentration, 2) using response factor of a compound in the same family as the detected compound, for a more accurate semi-quantitative estimate, or 3) using response factor for the pure standard of the detected compound for a quantitative measurement . The normal protocol that is used for quantitation is number (1) . Protocol (2) is significantly more costly since several pure compounds (if available) would be required to be purchased and much more time is required to perform the calibrations . Protocol (3) is the most costly since each detected compound needs to be purchased as a pure standard (often they are not readily available) and time is required to prepare each calibration standard.

Determining threshold limit values (TLVs) in milligrams per cubic metre (mg/m) is done by taking the TWA values presented in the reference literature in parts-per-million (ppm) and multiplying that value by the compound's molecular weight (MW) then dividing the product by the constant 24.45.

Ten (10) of the thirteen (13) compounds detected during the chamber testing are not listed in the ACGIH TLV Handbook (2009) to provide TWA values for calculation . Therefore a toxicological reviewand assessment of the testing data is recommended, per Section 9.3 of the Standard. None of the three (3) compounds with values available for comparison exceeded their respective TLV/100 values during the testing period . 11 CONCLUSIONS 1 . Testing performed in accordance with CAN/ULC-S774-09 produced an emissions profile containing thirteen (13) unique volatile organic compounds . The stipulated reference literature (ACGIH TLV Handbook, 2009) does not contain information relating to ten (10) of these compounds . Therefore, testing results for the Are deemed inconclusive, pending an asscbsnient froma toxicologist .

### APPENDIX A Analytical Method

SRCPublication No. 12650-1C09Confidential Report To V .O.C . Emissions Profiling of a Polyurethane Foam

Sample ANALYTICAL METHOD Calibration Procedure: The initial calibration of the thermal desorption systemis performed by using the TDU in the preparation mode, where a known concentration of the calibration gas vapour (normally toluene, but other compounds may be substituted by prior approval) is loaded into a clean tube. The tube is then desorbed in the operating mode into the GC/MSDsystem . This calibration check is performed regularly during the analysis of the sample tubes as a quality control check. The linearity of response of the calibration compound is checked by loading high levels of the compound onto the CarbotrapsT"' until non-linearity occurs. A lowlevel loading is also done to check on the lower limit of detection . The sample tubes are desorbed in the TDU at 300°C for 3 minutes. The desorption chamber is directly linked to the capillary column in the GC and any volatilized compounds are recorded on the total ion chromatogram(TIC) . Full scan mass spectra (m/e range 40-500) are acquired for the entire run . Any peaks in the TIC that have a signal/noise ratio greater than ten are processed through the library search routine for compound identification . Library matches are inspected by the operator to check for quality of the matches. The software also calculates a quality factor from0-100%

. Any compound with >90%quality are considered excellent . For compounds whose mass spectra do not give an excellent match, a code is assigned which indicates the level of confidence of identification (the codes range from 1-5) . These codes were previously described in Section 8.5. The best library matches occur when there are no interfering coeluting peaks and there is a high signal-to-noise ratio for the compound GC peak. For the same compound during the time of study, the quality factor may degrade when the signal gets very small .
