AAMA Releases Test Procedure and Quality Assurance
Guide for Thermal Barriers
December 14, 2009
The American Architectural Manufacturers Association (AAMA) has
announced the release of AAMA 505-09, a test procedure, and QAG-1-09,
a quality assurance processing and monitoring guide.
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
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 of
Azon USA Inc. and George Nash of 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."
