Built for 170 MPH winds.
Hawaii weather asks a lot of a roof. QuietCool's roof mount and solar attic fans are independently tested and certified to stay secure in high wind, so the system that keeps your home comfortable all year is built to the same standard as the roof it sits on.
What Windstorm Certification Means
Roof-mounted equipment becomes part of your roof system, so it should be engineered to the same standard. Windstorm certification is how that gets verified — independently, before the product ever reaches a home.
Certification means an independent laboratory — not the manufacturer — mounted the product exactly as it ships, loaded it to hurricane-force pressures, and confirmed it stayed secure and watertight. QuietCool's roof mount products are tested by Intertek under ASTM E330 (structural performance under wind load) and AAMA 501.1 (water penetration under dynamic pressure).
The result: certified models hold up to sustained wind speeds over 170 MPH — comfortably above Category 5 hurricane thresholds, and far beyond what a typical Hawaii roof will ever see.
The Certifications
QuietCool holds approvals from the two states with the most demanding windstorm requirements in the country.
Texas Department of Insurance
TDI approval is required for any product installed through a roof penetration in the Texas Gulf Coast windstorm counties — a program built specifically around hurricane exposure.
Florida Building Commission
Florida requires statewide product approval for roof installations, backed by third-party Intertek test reports under ASTM E330 and AAMA 501.1.
Certified Products We Offer
The windstorm certifications cover QuietCool's AFR series attic fans and RM WHF-2.0 roof mount whole house fans.

Roof mount whole house fans

Documentation for your permit
What these certifications give you is independent proof of how the product performs under hurricane-force wind load. If your building department asks for documentation, we'll provide the Intertek test reports and the Florida and TDI approval records for the exact model going on your roof.
Windstorm certification programs are run state by state, and Texas and Florida operate the two most demanding ones — which is why manufacturers test to those standards in the first place.
