Florida-made brands dominate for a reason
When it comes to hurricane impact windows, Florida-based manufacturers have a significant advantage — they build specifically for Florida's code requirements, climate conditions, and contractor network. Here's how the major brands compare.
PGT Innovations — the Florida standard
PGT is the dominant Florida impact window manufacturer, producing more impact windows for Florida homes than any other brand. Their WinGuard line is the most widely installed impact window in the state. PGT windows are built in Venice, Florida and designed specifically for Florida's wind loads and humidity.
- Best for: Most Florida homeowners — widest contractor network, best parts availability, proven track record
- Price range: Mid-range — $400–$750 per window installed
- Florida Product Approval: Comprehensive — approved for all Florida counties including Miami-Dade
CGI Windows — premium coastal performance
CGI (formerly known as Custom Glass Industries) produces premium impact windows with a strong reputation in South Florida's luxury market. Their SENTINEL and GUARDIAN lines are well-regarded for coastal performance and aesthetics.
- Best for: Coastal and high-end homes where aesthetics matter alongside performance
- Price range: Premium — $550–$950 per window installed
- Florida Product Approval: Full approval including Miami-Dade High Velocity Hurricane Zone
WinDoor — high-end performance
WinDoor produces premium impact windows and doors, particularly popular in upscale South Florida communities. Their products command premium prices but offer exceptional aesthetics and performance for luxury applications.
Andersen and national brands
National brands like Andersen produce impact windows for Florida but lack the Florida-specific expertise of domestic manufacturers. Their products are Florida Product Approved but Florida contractors often prefer local manufacturers for warranty support and parts availability.
More important than brand is Florida Product Approval number. Every impact window installed in Florida must have a valid Florida Product Approval (FPA) number. Ask your contractor for the specific FPA number for the windows being installed and verify it at floridabuilding.org. A reputable contractor will provide this without hesitation.
What to look for regardless of brand
- Design pressure (DP) rating — must meet or exceed your county's requirements. Miami-Dade requires DP50 minimum for most applications.
- Impact resistance rating — Large Missile Impact (LMI) is the highest rating for the main living areas. Ensure your windows carry this rating.
- Low-E glass coating — reduces solar heat gain, important for Florida energy efficiency
- Frame material — vinyl for inland areas, aluminum for coastal salt air environments
