AAMA 505-09, Dry Shrinkage and Composite Performance Thermal Cycling Test Procedure outlines a laboratory method to measure the amount of dry shrinkage and retained composite longitudinal shear resistance of extrusions incorporating a thermal barrier after thermal cycling. The process of thermal cycling described in AAMA 505-09 is referred to as the "differential" method and is to be used for product qualification of all types of thermal barriers.
AAMA QAG-1-09, Quality Assurance Processing & Monitoring Guide for Poured and Debridged Polyurethane Thermal Barriers is a quality assurance checklist for the in-plant processing of poured and debridged thermal barriers. AAMA QAG-1-09 includes information related to equipment checks, chemical storage and handling, process control, debridging and fabrication.
Both documents were developed by the AAMA Composite Thermal Barrier Testing Procedures Task Group, co-chaired by Patrick Muessig (Azon USA, Inc.) and George Nash (Ensinger, Inc.). "The improvement of the thermal performance of fenestration systems has become increasingly important in recent years," says Muessig. "These two documents describe the thermal test cycling methods known as the 'soak' test used for continuous quality checks and the 'differential' method used for product qualification."
AAMA 505-09 and AAMA QAG-1-09 are available to members at a cost per document of $10 for download, $20 for paper copy and $25 for CD. Non-members may purchase the documents at a cost of $25 for download, $50 for paper copy and $55 for CD.
