Why do you need lift pressurization? - TimesMojo

This inspection used ASTM Standard E1105 window water testing to evaluate window performance under real-world conditions. By applying negative pressure to the interior of the window while spraying water on the exterior, the test simulates wind-driven rain and exposes potential failure points.
