What Are Sliding Patio Doors?
Sliding glass patio doors are an easy way to connect indoor spaces to outdoor spaces. The large glass panels let the natural light in and provide a great ventilation option. The roller and track system on a sliding glass door utilizes a smaller footprint than a hinged French Door. When the sliding door is open, the roller system tucks the door away in front of the fixed door panel. A hinged door in the open position needs more space to operate than the sliding glass patio door. Find your replacement patio door at The Window Source.
The transition between inside and outside is welcoming with easy-open, horizontally sliding patio doors. Sliding glass doors have an unobstructed view when open or closed. Grill options can be added to match your personal design style or the architectural style of your home. Hardware that is stylish, durable, and color-matched also provides a customized look. All sliding glass doors from The Window Source come standard with color-coordinated handles.
Add your design style with brass, satin nickel, or oil-rubbed bronze options. Find your customized replacement patio door at The Window Source.
