Custom Exteriors installs Therma Tru Doors in the Bay Area

Therma-Tru: The Original Fiberglass Door.

25 years ago, Therma-Tru introduced a door that looked like wood but performed like steel. Now, they are the nation’s leading manufacturer of fiberglass and steel doors. Therma-Tru is one of the many companies we offer that creates energy-efficient doors. Fiberglass doors are more durable and energy-efficient than wood doors, and represent a significant savings in natural resources. We have been selling and installing Therma-Tru doors from the time we first opened the Custom Exteriors showroom and we still stand by their quality products.

Therma-Tru Doors first created the fiberglass entry door category 25 years ago with the introduction of their Fiber-Classic® wood-grained doors. Today, they are the nation's leading manufacturer of fiberglass and steel exterior door systems, and they are the most preferred brand of entry doors by builders and remodelers. Since the company's beginning in 1962, Therma-Tru Doors has been revolutionizing the home improvement industry with innovations and technologies in door systems. They've been improving millions of homes across the country with original door styles such the wood-grain lines of Classic-Craft® Oak, Mahogany, Rustic and American Style Collections™, our Fiber-Classic® and Smooth-Star® fiberglass doors, and our patio door selections.

Top Performing Fiberglass Doors Protect Your Bay Area Home.

Therma-Tru for fiberglass doors offer:

  • Tru-Defense Door System maximizes the seal between the door and the frame to keep out the damaging effects of wind and rain, and increases energy efficiency.

  • Impact Rated Glass products are a better way to protect your home against severe storm damage, including heavy winds, rain and flying debris. And, like other Therma-Tru products, they offer beauty and style for strong curb appeal.

  • Water Infiltration Tested door systems are thoroughly tested for water infiltration. The door, frame, sill, weather stripping, hardware, and more are tested for water leakage during a simulated rainstorm.

  • Thermal Deflection Testing uses high-powered heat lamps to measure the effects of extreme weather on our doors to ensure they can withstand the heat. Our doors’ performance is never compromised by air infiltration, cracking, swelling or warping.
