The American Architectural Manufacturers Association updated a document describing minimum requirements for various factors pertaining to rigid polyvinyl chloride (PVC) exterior profiles used in windows, doors and skylights.

AAMA 303-18, "Voluntary Specification for Rigid Polyvinyl Chloride (PVC) Exterior Profiles," was first released in 2000 and was last updated in 2012.

This voluntary specification establishes the minimum requirements for dimensional stability, impact resistance, weatherability, heat resistance, weight tolerance, heat build-up and lead compound content of rigid PVC exterior profiles including:

  • Ones used as frames, sash and all structural profiles related to glass retention and/or profiles that structurally divide lites within a common master frame of all vinyl products
  • Ones as described above, but are used in composite structures where PVC is combined with other materials such as wood, aluminum, steel, reinforced thermosets and reinforced thermoplastics
  • Ones used as cladding over wood, aluminum, steel, reinforced thermosets and reinforced thermoplastics

These profiles include, but are not limited to, those with decorative finishes such as paint, laminates and co-extruded capping compounds.

"Several new sections were added, including one giving base profile requirements for organically coated profiles, and one laying out co-extruded profile requirements," said Jeff Franson (Quanex Building Products), chair of the AAMA 303 Vinyl Profile Performance Standard Maintenance Task Group. "Other sections were updated as needed to reflect industry changes since 2012."
