From Lab to Lowcountry: How Storm-Rated Window Treatments are Proven Strong

Living in the lowcountry means embracing sunshine, sea breezes, and porches that stretch into the marsh, but it also means preparing for the hurricane season. Homeowners often hear terms like “hurricane-rated” or “storm-rated” when shopping for exterior shades, shutters, or screens. But what do those terms actually mean? How does a product earn the storm-rated title?
The answer lies in science, rigorous laboratory testing that pushes these products to their limits long before they ever make it to your home.
Simulating the Storm
Before a shade or screen can be labeled hurricane-rated, it must survive a series of carefully controlled experiments that replicate the harshest forces of a storm. Specialized testing facilities simulate extreme wind speeds, flying debris, and driving rain, conditions designed to mimic Category 3, 4, and even 5 hurricanes.
These trials don’t just ask, “Does it hold up?” They measure how a product bends, flexes, and recovers under immense stress, ensuring it can stand between your home and the chaos outside.
The Impact Test
One of the most dramatic tests involves projectile impacts. Engineers fire 2x4 wooden boards at hurricane speeds directly into the window treatments. The goal: to see if the material can resist penetration from debris that storms turn into dangerous missiles. If a screen or shutter can withstand these hits without tearing apart, it earns the right to be called hurricane-impact rated.

Wind & Pressure Testing
Another test simulates the violent push and pull of hurricane winds. Treatments are placed in a pressure chamber where air is rapidly forced in and sucked out, replicating the way gusts slam against structures and then drag at them with equal force. Products that can endure this without breaking, bending, or detaching prove they’re ready for real-world storms.
Did you know?
Before earning certification, hurricane-rated shades are tested in chambers that replicate wind speeds of over 100mph.
Rain Resistance

Finally, hurricane-rated products face water infiltration tests. High-pressure jets blast sheets of water against the shade or screen while fans mimic wind-driven rain. If the product keeps the water out, even under extreme conditions, it passes the final hurdle.
