The majority of Florida, especially Tampa Bay and coastal areas, are required to replace their glass with impact rated glass. When it comes to doors, there two two kinds of impact doors: WBD and HVHZ. For impact doors in the Tampa Bay area, WBD is sufficient for Florida Building Codes. HVHZ is only required in Broward and Dade Counties of Southern Florida.

WBD comes with either impact or non-impact glass. All of our prices on the entry door cost chart are specifically for WBD impact doors. If you want the added HVHZ protection, it is considered an upgrade and runs an additional $200 per panel for standard 6′ 8″ doors and $300 per panel for 8′ doors.
