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 had a proud heritage of philanthropy and a culture of doing the right thing in the communities where we do business. We are dedicated to continuous improvement, always looking for processes and materials that limit our 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 protecting 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.*

Recycling and Reduced Landfill Waste

We take measures at all of our facilities to ensure that our associates and manufacturing processes recycle waste products such as paper, plastic, cardboard, steel, propane canisters, wood, cut-outs and scrap doors. Since 2009, we’ve been recycling nearly 50% of the landfill waste stream at our Indiana facility. Therma-Tru uses 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.

 

Fiberglass Doors Mean Less Wood Use

Therma-Tru’s AccuGrain® process captures the fine graining detail of genuine high-end wood doors without harvesting endangered wood species, while offering superior durability and energy efficiency over wood doors, further reducing waste.

Sustainable Forestry

We partner with wood suppliers that utilize various certification standards including Sustainable Forest Initiative (SFI) and the State of Oregon's Forest Practice Act, to ensure that the wood products we use come from managed forests.
