Fenestration: Windows and Doors

Window and Door Testing and Evaluation

Doors, windows, and skylights share many of the same testing considerations and must have their code compliance verified according to the code-referenced standards and specifications, particularly AAMA/WDMA/CSA 101/I.S.2/A440, NAFS.

In accordance with the International Residential Code (IRC), International Building Code (IBC ), and HUD, all exterior doors are required to be listed and labeled. While this has been a requirement for a long time, now state and local officials are also enforcing it.

What NTA can do

NTA can evaluate doors and windows for everything from energy efficiency to performance in severe weather. NTA also has experience providing R&D testing, whether to determine if the product is code-compliant or meets internal needs.

NTA is approved to conduct testing for HUD programs, as well as Fenestration & Glazing Industry Alliance (FGIA)standards, and the Window and Door (WDMA) Hallmark Certification Program which is considered the mark of excellence among architects, contractors, and other specifiers and is accepted industry-wide. We also perform testing related to meeting the AAMA standards.

NTA can provide testing for:

  • Code compliance
  • Operability
  • Hurricane testing (windborne debris impact resistance)
  • Wind load testing (both WDMA Hallmark and the IBC requires that doors meet the standards of ASTM E330)
  • Static air pressure difference
  • Meeting AAMA standards for materials testing, water resistance, air infiltration, as well as for component parts (finishes, weather stripping, sealants, hardware)
  • Meeting HUD building products standards
