PGT® is the authority on impact-resistant windows and doors. Our expertise is founded from our collaboration with Miami-Dade County to establish testing protocols for impact-resistant products. As a result of this partnership, in 1996 PGT became the first manufacturer to offer a full-suite of impact-resistant windows and doors that are – to this day – among the strongest, safest, and most reliable products in the industry.

‘Engineered to perform’ is a phrase we use a lot when we talk about our WinGuard® impact-resistant windows and doors. It’s also a phrase we say with confidence because these products are engineered to meet the toughest hurricane codes in the nation. And because we’ve seen them perform, both in our test lab and in the “real world”, where more than three million units have been installed and zero impact failures have been reported.

The benefits of our flagship product line go beyond just hurricanes. WinGuard also protects against outside noise, break-ins, UV rays and high energy bills.
