For the first time since 2011, fiber-reinforced thermoset profiles are getting updated standards.

The American Architectural Manufacturers Association (AAMA) has put out an updated document establishing performance requirements for the profiles for use in fenestration products. This document references test procedures and requirements for standard weathering performance of fiber-reinforced thermoset profiles. It also addresses requirements covering design criteria, finish and appearance, weathering performance and physical properties, according to AAMA.

“It’s a keystone document for fiberglass reinforced pultrusions,” says Robert Plagemann, chair of the Fiberglass Material Council 305 Review Task Group. “A lot of the changes were editorial, and we did combine a lot of the requirements under one section so they were easier to understand. The section about weatherability is now under the section that covers general profile requirements, to make the document easier and simpler to use.”

Plagemann also says the changes made to the document went a long way toward making requirements consistent. “There were some requirements for patio door sills and different requirements for frames that are now the same from a weatherability standpoint,” he says. “The differences were significant but now they are unified.”

AAMA 305-15, along with other AAMA documents, may be purchased from AAMA’s publication store.
