Designed and tested to provide weather-tight performance

Residential windows are designed to help keep out the elements, whether it’s heat, cold, rain, wind, dirt, hail or snow.

Residential windows are tested to evaluate air, water, and structural performance. What that means is residential window testing evaluates a window’s ability to help keep wind, rain and other types of moisture outside a home, while maintaining the strength and structural integrity to keep the window opening itself intact.

About AAMA testing and certification programs

Residential windows are tested to simulate a variety of conditions your home may be subjected to, like how much air is kept out of your house in a high wind situation, or how much heat is kept out on a sizzling summer day.

Since 1962, AAMA Certification, the original third-party window performance program, has provided manufacturers with the means to independently demonstrate product performance to their customers.

The AAMA Certification Label tells customers that a sample of the product has been verified as conforming to the standards’ requirements through independent laboratory testing and follow-up on-site inspection of the manufacturer’s production line. View window safety brochures.
