If you're a do-it-yourself window installer, there are a few steps you must follow before your new windows are installed. These steps will help you ensure the quality of your new windows. The first step is to prepare your walls by laying down the appropriate amount of house wrap or weather resistant barrier. Next, you'll need to measure the size of your window frames and decide what type of installation is necessary. In addition, you'll need to cut a 6-inch angle at the bottom of each jamb.
To install new windows, you'll need to measure the frame of the old windows. To do this, you'll need to open the lower sash to take a measurement. To measure the frame, use a utility knife or a sharp object to trim away the peel-away backing. To install the window film, use a laminate roller and a heat gun. Having everything ready to go will save you time and effort.
Then, you need to measure the window itself. There are two ways to measure the space, but you should measure the size of your window carefully to ensure that it will fit properly. If you have an existing window, you should measure the depth of the opening and determine where it will go. Make sure it is not too deep or too wide - you want to be able to slide the window in easily without removing it. And don't forget about the sealant!
