Therma-Tru Exterior Doors for Homes & Businesses

As door installation specialists, we recommend Therma-Tru entry doors. This manufacturer turns out high-performance doors made of steel and fiberglass that are known for their beauty and durability. Founded in 1962, the company introduced the fiberglass door in 1983.

We feel confident about installing Therma-Tru doors at your home or business. This manufacturer is respected for innovation and quality. Plus, the doors they make are available in a wide range of colors with options such as decorative glass. This company makes products for both residential and commercial use.

Fiberglass Doors with the Beauty of Wood

Therma-Tru raised the bar on expectations for doors with that first fiberglass door. It had all the advantages of fiberglass with all the appeal of a product that looked just like wood. Wood is and always will be a perennial classic for doors, but with Therma-Tru’s fiberglass doors, you have the best of both worlds.

Fiberglass is an ideal material for doors that are handsome, strong, and durable.

The manufacturer offers two collections in wood-look doors – mahogany and oak. Their fiberglass doors realistically mimic the grain and pattern of these wood species and are available in a variety of colors.

As a composite material, fiberglass is made to be sturdy and stable. Because of this, you can expect your Therma-Tru door to guard the entryway to your home or business for many years to come. In fact, these doors come with a limited lifetime warranty from the manufacturer.

With Thema-Tru, you can even design your own door. First, simply choose from a wide selection of options, and then we install your new front door for you. Call our office to make an appointment for a free, on-site estimate.
