Vinyl Windows – Certified Manufacturers and Associations

Certified Manufacturers of Vinyl Windows - Associations

The AAMA Certification Label on a product tells customers that products have been verified as conforming to the ANSI/AAMA/NWWDA 101/I.S.2 standard's requirements through independent laboratory testing and follow-up on-site inspection of the manufacturer's production line.

Once certified, AAMA makes surprise visits to window factories. They walk in and simply take a randomly chosen window off the end of the assembly line. This window is shipped back to their labs for testing. If it fails, the window manufacturer can lose their certification.

The AAMA maintains an up-to-date list on its web site of all certified manufacturers of vinyl windows. The certification process is rigid and ongoing. Windows are periodically taken off assembly lines and tested by independent third party laboratories. The most recent guidelines are those written and published by the American National Standards Institute (ANSI) and AAMA. Each month, new manufacturers are certified for inclusion on this listing.
