What are hurricane impact windows?

Detailed Answer

Hurricane impact windows, also known as impact-resistant windows, are specially engineered window systems designed to withstand the extreme forces of a hurricane. They feature a laminated glass construction, which consists of two panes of tempered or heat-strengthened glass bonded together with a strong interlayer, typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This construction means that even if the glass cracks upon impact from flying debris, the interlayer holds the broken pieces in place, preventing dangerous wind and water from entering your home.

In South Florida, impact windows must meet rigorous testing standards, including the Miami-Dade County Notice of Acceptance (NOA) protocol, which is considered the gold standard nationwide. During testing, windows are subjected to large and small missile impact tests (simulating debris strikes at hurricane-force speeds) followed by thousands of cycles of positive and negative air pressure to simulate sustained hurricane winds. Products that earn a Miami-Dade NOA or Florida Building Code approval have proven they can protect your home in Category 5 conditions.

Beyond hurricane protection, impact windows deliver a host of everyday benefits that South Florida homeowners appreciate. They block up to 99 percent of harmful UV rays, protecting your furniture, flooring, and artwork from fading. They significantly reduce outside noise from traffic, construction, and aircraft, which is especially valuable near busy corridors like I-95, US-1, or Fort Lauderdale-Hollywood International Airport. And because they are always in place, you never have to scramble to put up shutters when a storm approaches.
