The American Architectural Manufacturers Association, AAMA, is a science based business organization whose primary goal is the promotion of quality, confidence and knowledge throughout the construction industry. It issues standards for a variety of products and materials and performs quality audits of manufacturers to ensure that those standards are met.

The AAMA has set rigorous standards for window product certification in four areas:

Dimensional Stability
Measures the ability of a window component to maintain its shape under variable stress producing factors. When these factors exceed a part's strength, distortion can occur, diminishing the window's performance.

Impact Resistance
Refers to how well a product resists damage during shipping, storage and installation.

Weatherability
There are two aspects of weatherability. The first concerns how well a material holds its initial color and resists fading over time. The second relates to a material's ability to retain its structural integrity.

Heat Resistance
Measures the material's ability to tolerate extreme heat without blistering, cracking or delamination.

All our windows meet or exceed the rigorous criteria set by the AAMA.
