AAMA

AAMA is the source of performance standards, product certification and educational programs for the window, door and skylight industry.

The American Architectural Manufacturers Association (AAMA) certification label serves the purpose of identifying fenestration products that conform within specific tolerances. The design and fabrication of fenestration models are tested in accordance with the procedures established by the AAMA Certification program and have met the requirements of the specification printed on the label. The fenestration products include windows, doors and skylights manufactured from aluminum, vinyl, fiberglass, composites and a combination of these materials with wood.

AAMA certification is third party certification. The third party is and outside organization not under the control of influence of AAMA. This third party is responsible for the validation and administrative functions for the program.

AAMA accredits independent third party laboratories that test the performance of the manufacturer's products. The most important function of certification is the assurance that products bearing the label do, in fact, meet the requirements of the standard. AAMA rates the window's ability to withstand wind loads, water resistance and the air infiltration rate. The higher the grade the better the window's performance.

Product Designation

AAMA certified window and door products are designated by a four-part code, which includes product type, performance class, performance grade, and maximum size tested. A typical code will look like this: 

HS - R - 25 - 48x76

In this example, HS is the product type, R is the performance class, 25 the performance grade and 48x76 the maximum size tested (width x height).

Product Type

The AAMA permanent labels are placed on sixteen different window product types. These products type designations and the abbreviated forms are shown below.

Performance Grade

Performance is designated by a number which follows the type and class designation. For example, Double-Hung Residential window may be designated HR15. The number establishes the design pressure, in this case 15 psf. The structural test pressure for all windows and doors is 50% higher than the design pressure which, for the example HR15 window, would have been successfully tested at 22/.5 psf structural test pressure.

Minumum design pressure, structural test pressure, and water resistance test pressures for the five classes in pounds per square foot are shown below.
