Can Impact Windows Withstand a Category 5 Hurricane? Here’s the Truth

What Category 5 Really Means

Winds over 157 mph. Flying debris. Roofs ripped off. A Category 5 hurricane is the real deal—and not many building materials can stand up to it without serious engineering.

How Impact Windows Are Tested

Impact windows aren’t just thicker glass—they go through missile testing and cyclical pressure testing designed to simulate hurricane conditions. Most high-quality impact windows are rated to withstand winds of up to 200 mph, depending on the product and installation.



It’s Not Just About the Glass

The entire window system matters—frame strength, installation quality, and even how your home is built. A strong window in a weak wall? Still a weak point. That’s why we only install code-compliant, professionally rated systems throughout Broward County.

Can They Handle a Cat 5?

Yes—if they’re rated for it and installed correctly. But no product is totally invincible. The real benefit of impact windows is preventing sudden pressure changes that can destroy your home from the inside out.

Why Impact Windows Still Make Sense

Even in worst-case scenarios, impact windows:

• Prevent debris penetration
• Reduce internal pressure damage
• Lower insurance premiums
• Provide 24/7 protection—no need for last-minute prep
