These Organizations Set the Standards. We Meet or Exceed Them.

All AMSCO® products are designed to meet or exceed the performance requirements of the following organizations. Click on the links below to learn more about each organization.

National Fenestration Rating Council (NFRC)
American Architectural Manufacturers Association (AAMA)

National Fenestration Rating Council (NFRC)
We manufacture all AMSCO windows using NFRC methods to evaluate energy performance. This means that you can rely on the information published on the AMSCO window panel to accurately represent the performance levels of each of our products. It's the best way to make informed choices about which products meet your energy needs.

In order to meet the NFRC guidelines, products are tested under predetermined criteria for:
  • U-factor
  • Solar heat gain
  • Visible transmittance
  • Air leakage

American Architectural Manufacturers Association (AAMA)
Our products meet or exceed strict air, water and structural performance standards as established by American Architectural Manufacturers Association. Tests include:
  • Resistance to air infiltration
  • Water leakage
  • Forced entry
  • Wind load pressure
  • Heat resistance (in excess of 300 degrees)
  • Weatherability (performance in various climates)
The AAMA certifies that our products have been tested and are manufactured and tested to their stringent performance evaluation procedures. AMSCO is enrolled in and certified under the AAMA Gold Label Certification Program.

You can be certain that your AMSCO purchase represents the finest in energy efficiency, because all AMSCO windows can earn the ENERGY STAR for meeting the strict guidelines set by the EPA and the US Department of Energy.
