The beauty, comfort, and luxury provided by Therma-tru doors are second to none in the home improvement industry.


The beauty, comfort, and luxury provided by Therma-tru entry doors and patio doors are second to none in the home improvement industry. The specialists at Therma-tru revolutionized door system technology when they invented the world’s first fiberglass door system in 1986. Fiberglass doors harness the durability of steel doors and the warm, welcoming beauty of wooden doors. Here at Northwest Exteriors, we want you to truly feel at home when you walk through the front door. This is why we are so excited to offer the latest fiberglass door and patio doors that look and feel just like real wood.

Therma Tru Performance Features

With the Tru-Defense system, standard on all entry and patio doors, you will be able to enjoy a higher level of security, energy-efficiency and a noticeable increase in comfort in your home. Unlike wooden doors, fiberglass will not warp or rot over time and you will find cleaning and maintaining your new door to be effortless.

Therma-Tru doors are not only strong and durable, they are also a beautiful first impression for your home. Therma-Tru Accu Grain technology imitates the most elegant styles of wood grain. Your friends and family won’t be able to tell the difference between a fiberglass Therma-Tru door and the look and feel of actual wood.
