Impact Door FAQs

What impact rating is required for doors in Monroe County?

All exterior doors in Monroe County must meet HVHZ large missile impact requirements. This includes passing the 9-lb 2x4 at 50 fps impact test and subsequent cyclic pressure testing with 9,000 cycles. Entry doors, sliding glass doors, and French doors all require valid NOA or Florida Product Approval for HVHZ.

What design pressure are impact doors rated for in the Florida Keys?

Impact doors in Monroe County typically require design pressures from +55/-65 PSF for standard residential up to +80/-100 PSF for elevated structures and commercial applications. Waterfront locations with Exposure D conditions require higher ratings due to increased wind loads.

Do sliding glass doors have different requirements than entry doors?

Sliding glass doors in the Florida Keys must meet the same HVHZ impact and pressure requirements as entry doors. However, due to their larger size, they often require heavier aluminum frames, reinforced tracks, and multi-point locking systems to achieve the required ratings.

Are there corrosion resistance requirements for doors in the Keys?

Yes, doors in Monroe County should meet AAMA 2605 or higher coating standards for salt spray resistance. Marine-grade hardware, stainless steel fasteners, and corrosion-resistant weatherstripping are essential for the harsh salt air environment of the Florida Keys.
