A Complete Door System

Quality tested to meet tough expectations. Genuine Therma-Tru ® components are put through multiple rigorous tests to help ensure that they will live up to a homeowner’s toughest quality and performance expectations. We even have our own engineering lab – approved to perform speci c test methods with a third-party witness* – as part of our ongoing commitment to ensuring that our products live up to our high standards for durability and reliability. Tested for endurance. The door is opened and closed repeatedly. The slam test is performed to commercial standards (AAMA 920), which are stricter than residential requirements, to help ensure long-lasting durability and reliability. Confidence on the coast. Components are immersed in a simulated salt water fog. The salt fog immersion test (ASTM B117) simulates a highly corrosive atmosphere to help ensure that components with metal nishes resist corrosion. Ready for winter weather. Exposing our glass to weather-like conditions helps verify that moisture and condensation will not get trapped inside. Resists deterioration and color fading. Components are subjected to accelerated amounts of UV (ultraviolet) light. Our QUV test helps ensure that weathersealing components and components with a colored nish resist deterioration and color fading with exposure to direct sunlight. Tough when you need it. A heavy object is repeatedly rolled back and forth over the sill. Our barrel roll test simulates moving household appliances in and out of the house on a dolly. This test helps ensure the long-lasting durability and reliability of our sills. Strength in a hurricane. Our Impact-rated doors pass a large missile impact test. We blast a 9 lb. 2" x 4" stud into the doors at 34 mph to prove they’re the better choice for strength and stability. Superior sound dampening. Therma-Tru Sound Transmission Class- (STC) rated Noise Reduction doors deliver aesthetics with a commercial level of performance for residential projects. High power testing. Design Pressure (DP) ratings are based on a Therma-Tru door system’s performance in Structural Wind Load. As an example: A DP-50 structural performance rating indicates that the door system has passed a structural test pressure of 75 lbs. per sq. ft. which is equal to a 165 mph wind. 7
