3 Page 1 of INTRODUCTION At the request of Soprema, Exova was retained to evaluate various wall section configurations using the Soprema Sopraseal Stick 1100T self-adhered membrane applied to exterior sheathing utilizing a framed construction configuration. The testing was conducted in accordance with CAN/ULC S referencing ASTM E as outlined in Proposal Number: Upon receipt, the specimens were assigned the following Exova Specimen Numbers: Client Specimen Description Exova Specimen No. Primary Air Barrier Material: Soprema Sopraseal Stick 1100T M Wall Specimen Description Opaque Wall Frame Construction: 3-5/8" Steel Studs, 18 ga.

Detail drawings for both wall sections (Exova Specimens M & 2) are located in Appendix E. 2.0 PROCEDURE Test Method Section (a), ASTM E , Section 9.1 Section Section Section (a), ASTM E , Section 9.1 Note: SI Units are the primary units of measure. Test Description Air Leakage Wind Pressure Loading Deflection Post Conditioning Air Permeance 2.1 Test Wall Construction Specimens M & 2 (Opaque & Penetrated Foundation Interface Wall Sections): The 10' x 10' test wall sections were constructed using commercially purchased steel studs (3-5/8" Steel Studs, 18 ga / 16 O/C. deep,) and built as per the construction details located in Figures A1.1 & A1.2 + A1.3 of ASTM E on June 17 18, 2015 The air barrier system was applied on the exterior side of the wall system with Soprema Sopraseal Stick 1100T at Exova s Systems Laboratory by representatives from Soprema on June 22-23, The air barrier application was also witnessed by representatives of Exova s Building Systems Laboratory staff.

4 Page 2 of Air Leakage Testing Testing was conducted in both exfiltration (-) and infiltration (+) cases. Upon mounting the wall system on the wall test apparatus, a sheet of 6 mil poly was draped over and sealed against the exterior face of the specimen s test frame utilizing sheathing tape and double-sided gasket material for extraneous air leakage measurement purposes. Using the procedure outlined in ASTM E , Section 9.1.2, the wall section was subjected to positive and negative pressures of: 25, 50, 75, 100, 150, 250, 300 Pa. Upon completion of the extraneous air leakage, the 6 mil poly was carefully removed and the actual specimen air leakage testing was conducted. As per ASTM E , Section logarithmic graphs for each air leakage test (infiltration/exfiltration) displaying the linear regression (r 2 > 0.95) values are located in Appendices A & B. The air leakage testing as described above was also conducted upon completion of the Wind Pressure Loading & Deflection portion as outlined in the standard. 2.3 Wind Pressure Conditioning The following wind pressure loading schedule was applied to the wall system using the loads prescribed for a sustained 1 in 50 hourly wind pressure difference of 650 Pa at a building height 12 meters above grade: Sustained Loads: Deformation Test (Sustained Pressure, P 1) The wall system was subject to increasing pressure in increasing stages for a minimum period of 10 seconds at each stage, up to a maximum pressure of 650 Pa which was maintained for 1-hour. Deformation Test (Sustained Pressure, P 1) The wall system was subjected to increasing pressure in increasing stages for a minimum period of 10 seconds at each stage, up to a maximum pressure of -650 Pa which was maintained for 1-hour. The deformation measurements were taken continuously during pressurisation. Note: As per CAN/ULC S742-11, Section , P1 air pressure differences are to be applied in 100 Pa increments. However, as testing was also conducted in conjunction with ASTM E , the loading increments used were 160 Pa stepping followed by the 650 Pa pressure hold (which exceeds the standard requirement of 550 Pa to match ASTM E ). This is considered a more severe stepping increment and is representative of the procedure outlined in CAN 07272, in which the CAN/ULC S742 standard is based. Cyclic Loads P 2 & P 2: Repeated Positive and Negative Pressure Test (Cyclic Pressure, P 2 & P 2) The wall system was subject to 2,000 cycles of pressure. The first 1000 cycles were from 0 to +950 Pa and was followed by 1,000 cycles from 0 to 950 Pa. The deformation measurements were taken continuously during cycling.

5 Page 3 of 19 Gust Loads, P 3 & P 3: 2.4 Deflection The wall system was then subjected to a Gust Wind pressure of Pa followed by a repeat Gust Wind pressure of 1410 Pa. These pressures were held for a minimum of 3 seconds. The maximum deformation readings were taken after each gust pressure. Upon completing the wind pressure conditioning sub-section, the wall specimens were subjected to wind pressure loading of ±1440 Pa for 10 seconds (exceeding the P2 and P'2 values as per CAN/ULC S742-11, Section 6.3.4) to match ASTM E , Table 2 Q10 > 0.40 kpa / 1440 Pa values. After completing the deflection loads above, air leakage testing was again conducted at ambient conditions at an exterior temperature of -20 C and the interior temperature of 20 C as per CAN/ULC S742-11, Section in both exfiltration (-) and infiltration (+) cases. 2.5 Test Dates Specimen Number Test Criteria Testing Date M Air Leakage (Exfiltration)-Prior June 25, 2015 Air Leakage (Infiltration)-Prior June 25, 2015 Wind Load Conditioning June 26, 2015 Wind Load Durability June 26, 2015 Air Leakage (Infiltration) Ambient June 27, 2015 Air Leakage (Exfiltration) Ambient June 27, 2015 Air Leakage (Infiltration) Cold June 29, 2015 Air Leakage (Exfiltration) Cold June 29, 2015 Specimen Number Test Criteria Testing Date M Air Leakage (Exfiltration)-Prior June 30, 2015 Air Leakage (Infiltration)-Prior June 30, 2015 Wind Load Conditioning June 30, 2015 Wind Load Durability June 30, 2015 Air Leakage (Infiltration) Ambient July 1, 2015 Air Leakage (Exfiltration) Ambient July 1, 2015 Air Leakage (Infiltration) Cold July 2, 2015 Air Leakage (Exfiltration) Cold July 2, 2015
