When it comes to your home, energy-efficient doors require less energy to heat your space than traditional products. That means savings on your monthly bills and comfort year-round.
For those who want to capture the elegant look of a French door but also need to save on space, we offer a French-style sliding patio door. The 5″ top rail, 7″ bottom rail and 3″ side rails further enhance the aesthetic appeal.
+Personalize Your Decorative Handle
The graceful contour of our French-style sliding patio door handles sets them apart. Each handle features a top lock for added resistance.
Our contemporary-style sliding patio doors have clean lines, symmetrical 3″ rails, and will add modern sophistication to any room.
+Save More Energy with SolarZone
We’re big fans of helping you save energy. Which is why we offer SolarZone™ insulated glass packages, which have proven to be far more effective than ordinary clear glass units. When you look at the performance data on the patio door’s glass label, you will see some numbers. 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.
Tradition never goes out of style. Our classic-style sliding patio door offers you the elegance and functionality you want in a sliding patio door. It’s generous 5″ rails and smart finishing details give any room a refined touch.
+Customize Your Decorative Handle
Add your personal touch to your contemporary-style or classic-style sliding patio doors with one of our beautifully crafted handles. The popular handle design features a convenient thumb latch for added appeal.
