Engineered to Work Together

Therma-Tru specifies all of the components to work together at the most critical points where an ordinary door system’s performance can fail, letting in air and moisture.By forming a tight seal against drafts and leaks, these components can help protect the door system and home against costly damage and deterioration.

Backed by our lifetime limited warranty.

We can stand behind more parts and for longer than other door companies because we make or specify everything that goes into our door systems. The homeowner has one source, Therma-Tru, to turn to if an issue arises with the door system.¹ Other companies either don’t warrant as many parts of the door system or warrant them for a shorter period of time. That could leave the homeowner without coverage and confused about who to turn to if issues arise.

The fiberglass difference.

With very little maintenance, a fiberglass door can bring a home years of beauty, durability and energy efficiency. Therma-Tru fiberglass doors offer the authentic look of wood. But, unlike wood, fiberglass will not warp or rot. And, unlike steel, it will not dent or rust. Built with a polyurethane foam core, Therma-Tru fiberglass doors insulate against cold and heat for exceptional energy efficiency.

Tested for endurance.

Go ahead and slam the door if you want. We did – over and over – to make sure our doors, glass and components 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.
