A New Standard in Doors

The new standards require manufacturers to conduct rigorous structural, air, and water testing of door assemblies in accordance with the North American Fenestration Standard (NAFS), AAMA/WDMA/CSA 101/I.S.2/A440. Masonite MP5 Entry Door System assemblies are manufactured, tested, and labeled in accordance with these standards.
