Hurricane & Impact-Rated Glass

In hurricane regions, storefronts and windows must keep the building closed when hit by wind-borne debris. We install impact-rated storefronts, doors and windows and replace impact glass in approved systems.

Why impact glass matters

When a hurricane breaks a storefront or window, wind rushes into the building and pressurizes it from inside, which can lift roofs and blow out walls. Impact-rated glazing is tested to resist being struck by debris and then to withstand cycles of wind pressure while staying in the frame, keeping the building envelope intact.

Code requirements

In wind-borne debris regions defined by the building code, exterior glazing must be impact-resistant or protected by approved shutters or panels. Florida’s High-Velocity Hurricane Zone, Miami-Dade and Broward counties, has the strictest testing and approval requirements, and products used there need an approval accepted in the HVHZ, such as a Miami-Dade Notice of Acceptance. Other coastal regions have their own requirements.

Impact systems, not just impact glass

The glass is laminated, often laminated insulated, with a strong interlayer.
The frame, glazing method and anchors are part of the tested assembly.
Installation must follow the product approval’s details.
Replacement glass must match the approved glass make-up.

Replacing impact glass

Impact glass that is cracked still holds the opening closed but must be replaced. We identify the system and approval, order matching glass, and reglaze with the approved method, whether structural silicone, glazing tape or wet seal.
