What Makes a Window “Hurricane Proof”?

Understanding Impact Window Ratings

Protecting your home from hurricanes starts with having the right windows. At Fonte Windows & Doors, we install impact windows Florida homeowners trust to protect against powerful winds and flying debris. But what exactly makes a window “hurricane proof”? And how do you know which ratings matter?

What “Hurricane Proof” Really Means

A hurricane-proof window is specially built to withstand strong winds, flying debris, and sudden pressure changes. These windows feature:

• Shatter-resistant laminated glass

• Reinforced, heavy-duty frames

• Secure installation to prevent blowouts

They’re designed to keep wind, water, and debris out—reducing the risk of damage or injury inside your home. Even if the glass cracks, it stays in place rather than shattering.

Key Impact Window Ratings to Know

Impact windows must pass rigorous testing before they’re approved for hurricane zones. The most trusted standards come from Miami-Dade County and ASTM International.

Here are the key tests and ratings to understand:

• Design Pressure (DP) Rating – Indicates how much wind force the window can withstand.

• Large Missile Impact Test – Simulates flying debris, like roof tiles or branches, hitting the glass.

• Small Missile Impact Test – Measures resistance to smaller objects such as gravel or hail.

Only windows that pass all required tests can be approved for use in South Florida hurricane zones.
