我做了30年的石膏工，总是把窗户包裹起来，用闪光来防止水侵入。然而，我看到屋顶工人做错了，油漆工试图这样做，问题总是影响灰泥。是否有泛闪光或空气屏障安装许可或认证?
Installing a window properly to avoid air and water leaks is left up to the installer, there is no certification that we know of. There are different ways to install windows that work, so one would hope that a window detail would be properly drawn by a designer. We agree with you that some installation techniques are bound to fail, or simple mistakes that could have been easily avoided can lead to higher energy bills from heat loss (usually air leakage around the frames), and water infiltration and damage if there wasn’t a strategy in place to avoid standing water and repel driving rain. Here is our page on window installation with some easy to follow tips that will improve the performance and durability –
How to install windows properly
I know the page doesn’t cover stucco specifically, but window installation should direct all water to the building exterior no matter what type it is.
You will see on that page two methods of air sealing we tried and we were really happy with how little air leakage we found when we relied not on caulking but rather on a high-performance building tape.
You can either purchase a flashing pan to collect and divert water or you can build your own with the right materials like we did in the window installation video on that page.
One of the most important details that I see people struggling with is when trying to fix and flash high performance windows in a building shell with exterior insulation. Using aninsulated window buck systemlike the one Legalett has developed is cost effective and gives an extended and insulating window reveal for securely fixing windows that makes it easier to h out and seal to prevent water ingress and condensation. A simple and cost effective solution that I recommend - and also useful for ICF construction.
