Windows are a beautiful and necessary part of a home; however, many people make mistakes during the installation that cause them to fail over time. By installing your windows properly, you will get years of use and enjoyment out of them. I’ve outlined the steps below on how to flash and install a window and included a step-by-step photo montage to help you follow along.
Pay attention to the details here and take your time. Windows and doors are the weakest point of the construction process as they are literally holes in your wall system. Take the time to install and protect them properly.
Additionally, I highly recommend that your windows be tempered glass if you’re building on a trailer. Keep in mind that as part of a moving vehicle, there is a lot of potential for broken windows. It’s not unheard of for rocks flung up by other vehicles and/or road vibration to break windows. Tempered glass is safer in these locations and may even be required in your area. If you are not building on a trailer, there are still requirements about when a window needs to be tempered. For example, if closer than 18″ to a floor, bathtub and/or shower as well as other restrictions. Be sure you know what those are so you can build safely and with the highest quality possible.
