Why Choose Therma-Tru Doors?
Performance, Protection and Beauty You Can Count On
When you choose Therma-Tru, you’re choosing a complete door system built to stand the test of time. Our products are backed by more than 60 years of expertise in material science, engineering and manufacturing.
Why Fiberglass?
Fiberglass won’t dent, rust, warp, split, crack or rot — unlike steel or wood. Therma-Tru fiberglass doors also feature durable construction that absorbs and deflects impact for lasting performance.
Industry-Leading Warranties
Therma-Tru stands behind our door systems because we make or specify every component that goes into our products. Our comprehensive warranties provide homeowners with extensive coverage backed by decades of proven performance.
Prefinished or Ready-to-Paint Doors
Choose a prefinished stained or painted door for quick, hassle-free installation or select a ready-to-paint option to create a look that’s uniquely yours.
How to Measure for a Door
Measure your existing rough opening from jack stud to jack stud, header to floor, and wall to wall. Read our Exterior Door Buying Guide for additional instructions and guidance.
Confidence in a Complete System
A Therma-Tru door system provides unmatched performance when it matters most — from exceptional protection against water infiltration to improved energy efficiency and unparalleled durability. Since we manufacture or specify every part of our door system, we can test each component to ensure it meets our highest standards — and yours.
