AAMA 1503-09, a voluntary test method for doors, windows and glazed wall sections, has been released by the American Architectural Manufacturers Association (AAMA).The test method, titled Voluntary Test Method for Thermal Transmittance and Condensation Resistance of Windows, Doors and Glazed Wall Sections, measures the thermal characteristics of doors, windows and glazed exterior wall sections under steady-state conditions. Specifically, measurements and calculations made using this procedure can be utilized to determine the thermal transmittance (air-to-air) or U-Factor, the air infiltration rate and/or the condensation resistance factor.

For AAMA 1503-09, calibration techniques were changed to reflect the significant improvement in window thermal performance over the years and sealing against potential air infiltration has been improved. Other calibration and test techniques were also refined. In addition, a component was added to allow for testing of multiple glazing options via AAMA’s 1505 glass library to provide simple, cost-effective and fully-tested U-factor and condensation resistance factor (CRF) values.

The Voluntary Test Method for Thermal Transmittance and Condensation Resistance of Windows, Doors and Glazed Wall Sections is available to members at a cost of $10 for download, $20 for paper copy and $25 for CD. Non-members may purchase the document at a cost of $25 for download, $50 for paper copy and $55 for CD.
