Over the years, strict building codes have been implemented in coastal areas to prevent excessive damage during tropical storms and hurricanes. A wide selection of Kolbe products can be upgraded to meet specific needs, including impact resistance in Zone 4 and High Velocity Hurricane Zones.
In a hurricane or tropical storm, the most damage generally occurs when the envelope of a building is breached by wind-borne debris. This causes a pressure difference between the interior and exterior of the building, and can occur due to window and door damage. For this reason, Kolbe submits its windows and doors to independent organizations which test them to rigorous protocols requiring specific wind loads and types of flying debris.
What makes Kolbe's impact-certified windows and doors stand out from the rest? Kolbe's impact products have the same beautiful appearance for which Kolbe windows and doors are known. No unsightly brackets or visible rods are necessary to hold the sash in place, and no extra locks are needed to fasten when time to evacuate is imminent.
An overview of our impact-certified products is below. For specific product information, including configuration and maximum size tested, please search using our Performance Class & Grade database.
