FMA, FGIA, WDMA: Guidelines for Window Replacement without Removal of Exterior Brick Veneer
This document is focused on the full frame replacement without removal of external brick veneer in cases where the cavity between the wall and façade needs to be blocked and sealed.
The Fenestration Manufacturers Association (FMA), the Fenestration and Glazing Industry Alliance (FGIA), and the Window & Door Manufacturers Association (WDMA) have released a new document focused on replacement windows. FMA/AAMA/WDMA 2710-20, Guidelines for the Full Frame Replacement of Windows without Removal of Exterior Brick Veneer, covers the replacement of windows in residential and light commercial buildings of not more than three stories above grade in height, utilizing a membrane/drainage system, a surface barrier drainage, or a wall system without a reliable membrane drainage system.
“This newly [developed] document is the first installation practice to address this window-wall condition, which also includes a ‘decision-tree’ matrix to guide installers to the most appropriate methods,” said Jim Katsaros of DuPont Performance Building Solutions, who serves as co-chair of the Joint Replacement Window Task Group. “The task group evaluated numerous configuration variations and completed representative installations with comprehensive field testing in actual homes in Baton Rouge, Louisiana. Based on learnings from the field testing, an easy to follow, highly illustrated, robust installation method was developed, bringing much needed clarity to the complex world of replacement window installations.”
