Testing a wall assembly to failure

There was one little hiccup when we wanted to test our R-Guard products up against real-world conditions of extreme weather: We lacked the ability to do so because the equipment didn't exist yet. So we built our own.

Enter what we call our design verification testing chambers, which can simulate hurricane conditions, including Category 5 winds, negative and positive pressure, and driving rains. These chambers allow us to test and measure what happens to all varieties of wall assemblies when they're subjected to the above extremes.

Matt Risinger, of YouTube's popular The Build Show, came to our headquarters in Lawrence, Kan., recently to see this massive rig for himself. The assembly included a German window and two smaller vinyl windows. Watch the 10-minute video to see the results of this test to failure.
