Exterior Fiberglass Doors San Antonio

Therma-Tru Entry Doors

Liberty Builders carries all types of fiberglass doors. All door brands go through a vast array of tests to ensure quality. 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. This is especially important for doors in San Antonio as temperatures can rise and fall to extremes within a matter of hours.

Fiberglass doors expand and contract less than wood or steel. They are resistant to temperature changes and can withstand extreme cold, heat, sun striking surface and sun baking surface behind storm door.

Fiberglass exterior doors also surpass high-quality steel doors in air infiltration performance. In testing conducted in accordance with AAMA 1702.2-85, fiberglass doors performed more than two times better than steel doors, measuring 0.10 CFM/FT2 compared to 0.22 CFM/FT2.

Security Front Doors

The statistics are almost shocking: according to the U.S. Department of Justice and the FBI, there are approximately 8,600 residential break-ins every day in the U.S. or one every 10 seconds. Most unlawful entry is not surprisingly through a doorway, with entry doors and patio doors the points of entry in 34 percent and 22 percent of break-ins, respectively. Therma-Tru is leading the fiberglass door industry in safety and security enhancements to its entry and patio door systems, introducing new features like multi-point locking systems and a security strike plate.
