3 Page 3 of 7 2 Introduction Intertek Testing Services NA Ltd. (Intertek) has conducted testing for Lenmak Exterior Innovations Inc. on the StrataClad product in accordance with AAMA , Voluntary Method and Specification for Pressure Equalized Rain Screen Wall Cladding Systems. The following test methods were followed in this testing: ASTM E (2012), Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen ASTM E , Standard Test Method of Structural Performance of Exterior Windows, Doors, Skylights, and Curtain Walls by Cyclic Air Pressure Differential ASTM E (2009), Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference AAMA , Standard Test Method for Water Penetration of Windows, Curtain Walls and Doors Using Dynamic Pressure. This evaluation was completed during the month of February Test Samples 3.1. SAMPLE SELECTION The client submitted the exterior metal composite wall panel to the Evaluation Center on January 25, 2013 and was identified as Coquitlam ID# VAN Samples were not independently selected for testing SAMPLE AND ASSEMBLY DESCRIPTION The product was identified as the StrataClad Wall Panel, an exterior paneling system constructed from custom-manufactured in. (1.25 mm) painted aluminum with 70% Kynar finish. The aluminum panels are filled with 0.8 lb. Icynene foam with a foil paper layer on top. The wall samples were assembled and installed by the client and their installer on February 5, 2013 at the Evaluation Center. The overall framing dimensions measured 120 in. wide x 120 in. high. The wall was composed of 3 main wall sections, each measuring 120 in. x 40 in. Framing was constructed with 20ga C- channel steel studs (6 in. deep x 2 in. wide) placed 16 in. o/c. Framing was then sheathed with 15/32 in. OSB and attached using #8 Tek3 screws. The wall sections were attached together using #12 x 1 in. Tek3 screws. The wall was then covered with Tyvek membrane and sealed with Tuck tape. A lower drip flashing, made from in. aluminum, was mounted to the wall and fastened every 16 in. o/c with #8 wafer head screws. The starter strip, made from in. aluminum, was mounted to the wall and fastened every 16 in. o/c with #8 wafer head screws. The reveal strip, made from in. aluminum, was mounted vertically to the wall and centered, and then fastened every 16 in. o/c with #8 wafer head screws. The corner trim pieces, made from in. aluminum, were mounted to the wall vertically and fastened every 16 in. o/c with #8 wafer head screws. GaskaTape v700 was then applied to the reveal and corner trims to aid in water sealing. The panels are then installed to the wall using 100 plastic horsehoe

4 Page 4 of 7 spacers and #12 x 1.5 in. Tek3 screws spaced every 12 in. o/c. The top cap flashing, made from in. aluminum, was then mounted to the wall and fastened every 16 in. o/c with #8 wafer head screws. Refer to Appendix A for drawings of the tested wall sample. 4 Testing and Evaluation Methods 4.1. AIR LEAKAGE The Air Leakage tests (Air Infiltration) were conducted in accordance with ASTM E283. The tests were performed using a test pressure of 75 Pa (1.57 psf). As per AAMA 508, air leakage was induced in the system to provide a leakage rate of 0.6 L/s*m 2 (0.12 cfm/ft 2 ). 196 holes, each measuring 1/8 in. diameter, were drilled into the sheathing to achieve the required air leakage PRESSURE CYCLING The Pressure Cycle test was tested in accordance with ASTM E1233 and evaluated to AAMA The test was preformed at a specified pressure differential of 240 Pa (5 psf) to 1200 Pa (25 psf) for a minimum of 100 three-second cycles WATER PENETRATION STATIC The Static Water Penetration test was tested in accordance with ASTM E331. This test was performed at the specified pressure differential of 720 Pa (15 psf) and a water spray rate of at least 204 L/m 2 per hour (5.0 U.S. gal/ft 2 per hour). The test was run for fifteen minutes, during which the pressure and water spray were continuously applied WATER PENETRATION DYNAMIC The Dynamic Water Penetration test was tested in accordance with AAMA The test was performed at the specified pressure differential of 720 Pa (15 psf), or 120 kph (75 mph) wind speed equivalent, generated using a Pratt and Whitney R-2800 Aircraft Engine, and a water spray rate of at least 204 L/m 2 per hour (5.0 U.S. gal/ft 2 per hour). This test consisted of fifteen minutes, during which the pressure and water spray were continuously applied.

AIR LEAKAGE Air leakage test data is indicated in the following table: Test Pressure for all samples: 75 Pa Overall Area of each sample: 9.42 m 2 ( ft 2 ) Air Leakage: L/s*m 2 (0.125 cfm/ft 2 ) 6.2. PRESSURE CYCLING During the Pressure Cycling at a pressure differential from 240 Pa (5 psf) to 1200 Pa (25 psf) for 100 cycles the systems lag times was below the required 0.08 seconds and the differential between the cavities and cyclic wind pressure did not exceed 50% of the maximum test pressure. All samples tested met the requirements as specified by the client for Pressure Equalization and as per AAMA STATIC WATER PENETRATION During the 15-minute test period, using a pressure differential of 720 Pa (15 psf), there was no water leakage observed through the tested sample. The sample met the requirements as specified by the client for Static Water Penetration and as per ASTM E DYNAMIC WATER PENETRATION During the 15-minute test period, using a Pratt and Whitney R-2800 Aircraft Engine to generate a pressure differential of 720 Pa (15 psf), no water leakage was observed through the tested sample. The sample met the requirements as specified by the client for Dynamic Water Penetration.
