AAMA Provides Updated Performance Standards for Cellulosic Composite Profiles and Laminates

Performance testing requirements for cellulosic composite profiles, as well as laminates made of such composites and wood, are addressed in two related documents released by the American Architectural Manufacturers Association (AAMA).

"These updated standards are based on research, testing and years of experience by compound and additive suppliers, profile extruders and window fabricators, who are collectively represented by the Wood and Cellulosic Composite Materials Council of AAMA," said Larry Livermore, technical standards manager for AAMA.

AAMA 311-05, "Voluntary Specification for Rigid Thermoplastic Cellulosic Composite Fenestration Exterior Profiles,"covers performance standards relating to dimensional stability, screw withdrawal, thermal cycling, weatherability, heat resistance, heat build-up and lead content for rigid composite profiles used in doors, windows and skylights. AAMA 312-05, "Performance Requirements for the Lamination of Wood and Cellulosic Composite Profiles," focuses on performance standards and test procedures dealing with the lamination of wood and cellulosic composite profiles used in fenestration products.
