Rigorous testing standards and methods assure the performance of Simonton windows
and doors. To pass these tests, the product must endure conditions that are more
intense than a window or door is likely to ever experience in your home.
All Simonton manufactured windows and doors are tested to meet AAMA/NWDA 101/I.S.2-97
for structural issues and NFRC 100 and NFRC 200 for thermal concerns. (AAMA=American
Architectural Manufacturers Association; NWDA=National Window Door Association;
NFRC=National Fenestration Rating Council)
