The document, developed to assist architects, manufacturers, designers and/or owners, establishes assembly guidelines for aluminum composites utilizing polyamide thermal barriers.“With the publication of the QAG-2-12, AAMA now has four documents dedicated to design, manufacturing and resultant composite properties of thermal barriers in aluminum fenestration,” says Patrick Muessig, Chair of AAMA’s Thermal Barrier Task Group. “As energy efficiency has recently been, and will continue to be, an extremely important issue, the creation of these documents aid in the perpetuation of quality in thermally advanced commercial fenestration.”Developed by AAMA’s Thermal Barrier Task Group, QAG-2-12 covers handling and storage of polyamide thermal barriers, assembly equipment and machinery inspection, quality control and handling and care of completed and assembled profiles.Thermal barriers create a thermal break between the inner and outer surfaces of aluminum fenestration, which allows for the reduction in heat loss or heat gain.Specifically, polyamide thermal barriers are comprised of an extruded thermoset material typically consisting of polyamide, reinforced with 25 percent of glass fibers for use in fenestration systems such as curtain walls, storefronts, windows, doors and skylights.
QAG-2-12 references important industry documents which include TIR A8-08, Structural Performance of Composite Thermal Barrier Framing Systems and AAMA 509-09, Dry Shrinkage and Composite Performance Thermal Cycling Test Procedure.
QAG-2-12, Voluntary Quality Assurance Processing Guide for Polyamide Thermal Barriers is available for AAMA members to download at a cost of $10. Non-members may purchase the document at a cost of $30 for download. The specification is also available for purchase on CD and hardcopy. To order QAG-2-12, visit AAMA’s Publication Store.
