Therma-Tru offers impact-rated doors and glass that can be used to meet high-wind and coastal region codes and regulations. These offer excellent performance in extreme weather conditions while providing added protection. All impact-rated doors pass a large missile impact test where Therma-Tru blasts a 9 pound 2” x 4’ stud into the doors at 34 mph to prove they are the better choice for strength. It is important when it comes to impact door usage that building code requirements are reviewed in the area of purchase to ensure all codes are met.
