Are patio doors energy efficient?

Yes. Window World of D.C. 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.

What Your Neighbors Are Saying

The windows and the door we had installed by Window World in our double wide mobile home are really beautiful. The workers were really nice and really worked hard in this hot sun. We would like to have the same 2 guys in the future if we have other needs, like replacing our patio door.

I had all my windows and one of two sliding glass doors replaced in my Townhouse rental 4 years ago. Next month or early Spring, I intend on replacing the last sliding glass door. Arthur was my estimator and hope he is still there when I call/email. The quality of their windows is great, but I absolutely love the sliding door quality and features (locking mechanism(s), sound proofing and insulation etc.
Carter S.
We were very pleased with Window World’s service. They met every deadline, they were prompt, courteous and professional. Our windows look great, and we can tell that they are much more efficient than our old windows. We highly recommend Window World.
