Add elegance to your home with our Fiber-Classic® Sliding Patio Door System. Our fiberglass patio doors have the same style, durability, and security that you would expect from a Therma-Tru entry door.

Choose an exterior finish in white, stone, almond, or bronze, and paint or stain the wood-grain interior of our patio doors to match your home’s décor.

The Low-E insulated glass in our back patio door systems is designed to let in the maximum amount of light while maintaining your home’s internal temperature. This special glass has the added benefit of protecting your furnishings from fading and exposure from UV rays.

Create the feel of a retreat with our Smooth-Star^® Sliding Patio Door System, featuring the smooth look of fine-painted wood with the durability of fiberglass.
