Therma-Tru Patio Doors

For those rooms where you want the best view and the sun to pour in, Therma-Tru's Fiber-Classic Patio doors frame the outdoors with the warm, rich look of wood, only with far more energy efficiency. Patented Fiber-Classic doors feature a solid polyurethane core providing five times more insulation than wood.

Therma Tru Patio Doors feature fiberglass panels that won't split, warp, crack or dent. Additional system features include:

- Preservative treated bottom inner core of sill providing a superior seal with subfloor

- Adjustable oak or self-adjusting sills that interact with door gaskets to keep out air and water. Outer ramp available in either natural aluminum or bronze finish.

- Precision-cut, brass/zinc dichromate hinges are made of heavy gauge steel that resist corrosion.

- Weatherstrip seals tightly, remains flexible and is removable for finishing.

The active door is machined to accept virtually any make or model of locking handle and security deadbolt sets. Locking hardware can be keyed alike and matched to existing styles and finishes.

The insulated double strength glass in our Fiber-Classic Patio doors is uniquely assembled into the door panel during manufacturing, making the door and glass one solid piece. Water and wind won't penetrate. Low-E glass is available.
