Independent Testing
Wind-uplift test results.
A QDEK-bonded roof assembly, put through the roofing industry's wind-uplift test by an independent laboratory.
What the report says
- Test method
- ANSI/FM 4474 simulated wind-uplift test, 5 × 9 ft chamber, pressure increased in 15 psf steps and held 60 seconds at each step.
