Veeer window5/6/2023 ![]() ![]() Instead, the decision was made to isolate the windows from the brick wall and the wood frame behind it. The principle of membrane drainage behind the wall façade simply did not apply. Inspection revealed that, in general, there was no intact drainage plane to be identified behind the existing brick, so the decision was made to isolate the replacement windows from the walls.īecause field conditions varied so widely, the committee decided to treat the surrounding wall system in each of the three homes as an unknown factor that could not be relied upon for robust integration from an air- and water-management standpoint. The houses we worked with in Louisiana, however, were built in the 1950s through the 1980s (when there was no statewide building code), and they all lacked functioning WRBs behind the brick. In those stories, the authors describe attempting to integrate the window flashings into the existing weather-resistive barrier behind the brick. JLC has covered the installation of replacement windows in brick veneer walls before (“ Replacing Windows in Brick Veneer Homes,” Coastal Contractor, May/07 “ Installing Full-Frame Replacement Windows,” JLC, Oct/13). In the next few pages, I’ll describe how we installed and tested the windows and what we learned from the process. With help from committee members, industry representatives, and a local contractor, we installed two windows in each of three houses using various materials and methods and then tested the installations for water leakage using the standard test method ASTM E 1105. I located several buildings in Louisiana that had been damaged in the 2016 floods and were gutted and standing empty. But this time, the idea was to demonstrate and test a method of installing replacement windows in a realistic setting. In those cases, the methods were tested and proven using mocked-up walls built in a laboratory setting. The FMA/AAMA/WDMA Installation Committee has created a number of similar documents pertaining to new construction. The crew pulled existing single-glazed windows from the openings. The author identified several existing homes that were gutted and standing empty. Once completed, the document will be used for the training and education of field crews and supervisors. This year, I’ve been helping an industry committee of the Fenestration Manufacturers Association, the American Architectural Manufacturers Association, and the Window and Door Manufacturers Association develop a standard of practice for installing replacement windows in existing brick veneer–clad residential buildings, without removing the brick cladding. Modify installation details to fit the climate and exposure. ![]() ![]() Ensure that materials used are compatible.Avoid creating horizontal surfaces that could limit drainage.Install materials “shingle style” (what is below is covered by what is above).In my view, the same basic principles that apply generally to exteriors also apply to window installations: More recently, I took the Installation Masters Certification course from the American Architectural Manufacturers Association, which gave me a stronger technical background and the confidence to install windows in a variety of situations. Over the years, I have learned about window installation on the job. I’ve been in the construction industry for more than 30 years, much of that time as a licensed contractor. ![]()
