Fenestration and Glazing Industry Alliance Updates Guidelines and Technical Documents

The Fenestration and Glazing Industry Alliance (FGIA) has updated several
documents, offering new guidance on topics such as sloped glazing, sealants and fenestration anchorage.

Skylights

AAMA PSSG-20, Selection and Application Guide for Plastic Glazed Skylights and Sloped Glazing, is intended to provide an understanding of the value and effective application of plastic glazed skylights and sloped glazing in a building design as well as the features and benefits of different plastic glazing materials. This is the second update to the document since it was published in 2016.

“PSSG provides … guidance to best leverage plastic glazed skylights and sloped glazing advantages by giving sound technical information on the various aspects and considerations that need to be taken into account when incorporating them into a building design,” said Neall Digert (Solatube) and John Westerfield (CrystaLite), two leaders within the Plastic Glazed Skylights and Sloped Glazing Review Task Group, in a joint statement about the document.

Sealants and Anchorage

FGIA also has updated a technical document that aids in the selection, use and application of sealants commonly used in fenestration systems. AAMA 851, Fenestration Sealants Guide for Windows, Window Walls and Curtain Walls, an FGIA standard, is the first update to this document, which was published originally in 2009. It reviews the type of sealants currently in use and their application following accepted standard practices. AAMA 851 encompasses both field and factory applications.

FGIA has updated two documents addressing fenestration anchorage. This is the first update to AAMA 2501-20, Voluntary Guide for Engineering Analysis of Anchorage Systems for Fenestration Products, included in the North American Fenestration Standard (NAFS), since it was originally written in 2006. Its companion document, AAMA TIR-A14-20, Fenestration Anchorage Guidelines, was created in 2010. This is also its first update.

“These documents are companions, and both provide guidance on what needs to be considered to determine appropriate anchorage of fenestration products,” says Sarah Erickson of Wausau Window and Wall Systems, chair of the FGIA Fenestration Anchorage Systems Task Group.

AAMA 2501 establishes the minimum requirements to confirm that a fenestration anchorage system for a product included in NAFS provides a load resistance with an appropriate safety factor that is equal to or greater than the project specific design pressure requirements and supports the product in a manner equivalent to that tested. AAMA TIR-A14 offers engineering rules and guidelines in the designs of fasteners used in the connection of fenestration to the surrounding building conditions.

All of the documents are available online.
