Best Impact Window Brands: Miami-Dade Approved Guide
A comprehensive guide to the top impact window brands approved for Miami-Dade County's HVHZ zone. Compare PGT, CGI, Eco, ESWindows, and more.
Choosing the right impact window brand is crucial for South Florida homeowners. Not all brands are created equal — and in Miami-Dade County's High-Velocity Hurricane Zone (HVHZ), only NOA (Notice of Acceptance) approved products are allowed.
What Makes a Brand "Best"?
When evaluating impact window brands, we look at five key factors:
- Design Pressure Ratings: How much wind load can the window withstand?
- Large Missile Impact Rating: Tested against a 9-pound 2x4 lumber at 50 feet per second
- Energy Efficiency: U-Factor, SHGC, and Low-E coatings
- Warranty Coverage: Frame, glass, and hardware warranty terms
- Aesthetic Options: Frame colors, glass tints, and grid patterns
