Changes to CSA A440.6 fenestration installation standard open for public comment
By Patrick Flannery
The Canadian Standards Asspciation is updating A440.6 Installation of High Exposure Fenestration Products and has released a draft of the standard for public review. The section is mostly directed at Part 5 commercial construction, but low-rise Part 9 buildings could be affected as well when they have windows and doors exposed to high levels of wind and rain, especially on hills and cliffs. A440.6 sets forth characteristics of effective and durable installation methods, in both new and existing buildings, of fenestration products within the scope of AAMA/WDMA/CSA 101/I.S.2/A440 that are intended for installation in high exterior exposure conditions.
