Thanks to decades of material science expertise, Therma-Tru doors are made from super-natural, better-than-nature materials proven to outlast and outperform wood and steel.
The industry's first fiberglass door delivers the look and feel of real wood grains - or a smooth, paintable surface - with excellent performance and value.
Smooth-Star entryways with our handcrafted and professionally applied PrismaGuard premium stain or paint are backed by a 10-year limited finish warranty.
A Therma-Tru fiberglass door system is backed by our comprehensive lifetime limited warranties.
Choose from our wide array of glass designs to create a beautiful, durable entrance that showcases your high standards for style, quality and craftsmanship.
Therma-Tru offers a door system that delivers continuous protection against forced entry, providing invaluable peace of mind.
From our industry-first fiberglass - made from a proprietary blend of advanced materials - to our innovative PrismaGuard finish, our door systems are built to last.
Fiberglass doors have up to four times the insulating R-value of wood; ours feature a polyurethane foam core, an energy-efficient insulating material.
A Tru-Defense door system installed by a Therma-Tru Certified Door System Installer doubles your reimbursement eligibility.
