Therma-Tru Doors Can Take the Heat

As part of Therma-Tru’s rigorous product testing, our doors are tested against extreme weather conditions. Severe temperatures can eventually lead to compromised performance, including air infiltration, cracking, swelling or warping. Our Advanced Technology Center uses high-powered heat lamps to measure the effects of extreme weather on our doors to ensure they can withstand the heat.
