Therma Tru Doors

We invented the fiberglass door because we believe it combines the best characteristics of wood and steel – beauty and performance – without the compromises. And we remain committed to making smart, innovative new products – such as the Classic-Craft Canvas Collection and vented sidelites. Therma-Tru Doors are better and more beautiful every year.

The Fiberglass Difference

Fiberglass doors look like wood, but they don’t warp or rot like wood, or dent or rust like steel. In fact, a fiberglass door needs only a fraction of the maintenance wood and steel doors do. And the inside of a Therma-Tru fiberglass door is filled with an exceptional heat- and cold-resistant material that helps keep your home warm in winter and cool in summer.

Tested for Endurance

Go ahead and slam the door if you want. We did – over and over – to make sure our doors, glass and parts live up to your toughest expectations. We expose them to extreme weather conditions. We roll heavy objects over our sills. We immerse parts with metal finishes in corrosive salt atmospheres. And we expose them to ultraviolet (UV) light to make sure our weathersealing parts and metal finishes can resist deteriorating and color fading in the sun. That’s how we know that a Therma-Tru door is designed to stand up to almost anything life throws at it.
