FGIA updates weatherstrip and weatherseal document

May 3, 2023  By Fenestration and Glazing Industry Alliance

The Fenestration and Glazing Industry Alliance has updated a document establishing minimum performance requirements for pile weatherstrips and replaceable weatherseals. AAMA 701/702-23 Performance Specification for Pile Weatherstrips and Polymer Weatherseals, an FGIA document, provides details on test methods, equipment, specimen sampling techniques, minimum performance levels, criteria for waivers and a report format. It is now available for purchase in the FGIA online store. This document was last updated in 2011.

“Through the use of this document, weatherstrip and weatherseal producers are able to demonstrate that a component can help ensure proper sealing against air leakage and water penetration when used by FGIA-certified window and door manufacturers,” said Todd Burroughs of Intertek, chair of the document’s developing group, the FGIA Weatherstrip Committee.

AAMA 701/702 is used for laboratory verification of weatherstrip and weatherseal products as a requirement for meeting minimum levels of performance for the sealing of fenestration products, establishing recognized criteria of quality and performance for pile weatherstrips. This information is of use to manufacturers, distributors, users and laboratories.

AAMA 701/702, as well as other documents available from FGIA, may be purchased from the online store at the discounted member rate of $20 or the non-member price of $60.

    My house has:
    printed inside the window. One of the windows has a broken seal and It is fogged.
    What is the expected time use of a window?
    The print inside the window is facing outside, not inside like all the others. Could like have been a factor is the broken seal?

      Hi, Joan. The lifespan of an insulating glass unit varies considerably depending on a number of factors. Most windows come with a warranty – suggest you consult that and/or contact your dealer/manufacturer.

      The label on the wrong side does indeed suggest the window may have been installed backwards, which could affect the stresses on the frame and cause a premature failure of the seal. However this is not certain – it’s possible the label is simply on the wrong side of that window.

      Phil Lewin at the Siding and Window Dealers Association of Canada is an excellent resource for these questions. You can find contact information for SAWDAC at sawdac.com.

      Another resource is the Fenestration Association of BC: fen-bc.org. They are part of the Fenestration and Glazing Industry Alliance, which administers the IGMAC insulating glass standard referenced on your window.
