SLIM-X ULTRA
Slim X Ultra combines minimalist design with demonstrated structural strength. Testing by Thomas Bell-Wright recorded AW-PG40-HS for the tested specimen—placing it in Architectural (AW), the highest of the four NAFS performance classes: R, LC, CW and AW. The specimen passed structural pressure testing at ±1,920 Pa and proof loading at ±2,880 Pa, with no visible damage after proof loading. It also passed air infiltration testing at 300 Pa and water penetration testing at 500 Pa, with no water leakage observed. Download the full report below for the test conditions and results.
SLIM-X WALL
Slim X Wall combines minimalist framing with demonstrated structural strength. Testing by Thomas Bell-Wright recorded AW-PG40-FW for the tested fixed-window specimen—placing it in Architectural (AW), the highest NAFS performance class. The specimen passed structural pressure testing at ±1,920 Pa and proof loading at ±2,880 Pa, with no visible damage after proof loading. It also passed air infiltration testing at 300 Pa and water penetration testing at 600 Pa, with no water leakage observed. Download the full report below for the test conditions and results.
SLIM-X LITE
Slim X Lite demonstrated effective air and water resistance in testing by the Housing and Building National Research Center (HBRC) in September 2024. The tested sliding-window specimen recorded air leakage of just 0.05 L/s/m² at 300 Pa, well below the report’s allowable limit of 1.52 L/s/m², and showed no water leakage at 300 Pa during a 15-minute test. Under structural loading of 1,000 Pa, deflection measured 6.24 mm, within the permitted 14.57 mm limit. Download the full report below for the test conditions and results.
