Therma-Tru - Environmental Responsibility

Download Brochure

As the pioneer of the fiberglass exterior door industry and the most preferred brand in the business, Therma-Tru is committed to the responsible use of natural resources in creating high-performance entry and patio door systems.

Since our founding in 1962, Therma-Tru has a proud heritage of philanthropy and a culture of caring in doing the right thing in the communities where we do business. Through our dedication to continuous improvement, we are always looking for processes and materials that limit the impact on our environment.

Below are some sustainable attributes of Therma-Tru products and practices that can apply to a variety of green building standards including LEED1 and NAHB2.

Energy Efficiency

Therma-Tru’s fiberglass entry door systems are ENERGY STAR compliant and NFRC3 Certified helping homeowners save money on energy costs and protect the environment through superior energy efficiency. Filled with polyurethane foam4, Therma-Tru fiberglass doors provide as much as four times the insulation of most wood doors.*

Superior Sound Insulation

The polyurethane foam inside Therma-Tru’s doors not only provides superior thermal insulation, it also helps insulate against noise pollution. The ability a material can block sound is commonly measured by STC5 ratings. The higher the number, the better sound insulation.


Therma-Tru takes measures at all of our facilities to ensure our associates and processes recycle waste products. The company works with several waste management organizations to recycle products such as paper, plastic, cardboard, steel, propane canisters, wood, cut-outs and scrap doors. In fact, we recycled nearly 50% of the landfill waste stream at our Indiana facility in 2009, a 80% increase since 2006.

Use of Recycled Content

Therma-Tru qualifies recycled products for its composite wood end rails and sill substrates (materials in the bottom and top of the door) such as recycled wood chips and plastic bottles.

Reduced Landfill Waste

We’re always looking for new ways to recycle waste products to help reduce landfill waste. We have plans for each of our facilities for continuous improvement in this area. For example, we reduced landfill waste per door at our Indiana facility by 32% from 2008 to 2009.

Fiberglass as a Wood Substitute

ThermaTru's proprietary AccuGrain Technology captures the fine graining detail of genuine high-end wood doors without harvesting endangered wood species like Honduran Mahogany.Therma-Tru’s proprietary AccuGrain™ Technology captures the fine graining detail of genuine high-end wood door without harvesting endangered wood species like Honduran Mahogany. Plus, fiberglass doors offer superior durability and energy efficiency over wood doors.

Sustainable Forestry

The wood products used in Therma-Tru Door systems such as the door frame components come from managed forests. Therma-Tru partners with wood suppliers that utilize various certification standards including SFI6, CERTFOR Sustainable Forest Management Standard, and the State of Oregon’s Forest Practice Act, to ensure that the wood products it uses come from managed forests.
