Yes. Window World of Cleveland’s Sliding Patio Doors are some of the only ones on the market that help you achieve thermal protection all year long. Each door comes with dual internal/external weatherstripping, a compression bulb seal, closed-cell foam gaskets and a 1″ thick insulated glass unit with a warm-edge spacer system, resulting in a tough shield against energy loss.
+Save More Energy with SolarZone™
We offer SolarZone™ insulated glass packages, which have proven to be far more effective than ordinary clear glass units. How to read the data: The lower the U-Value (also known as U-Factor), the less energy you’ll need to heat your home. The lower the solar heat gain coefficient (SHGC), the more you’ll conserve on air-conditioning.
