Window Jamb – A replacement window is different from every home and instructions for installing replacement windows. The instructions and tips given below will be the basic instructions that you can follow, but keep in mind that they may not be suitable for your home. Replacement windows are designed to fit any window openings. You can get it in sizes ranging from sixty eight to narrow 11½. You can get it on wood instead of aluminum, glass fiber, wood and vinyl wood. Before you continue, you should note that there are three basic types of replacement windows; full frame unit, sash kit and insert a replacement.
The first thing you need to do if you want to install a replacement window is to first measure your window (which you want to keep). This means you measure the frame. To do this, you must. Measure the width of the window frame (make sure you measure from the inside of your house). Measure the top, middle and bottom (jaw to the jaw) and note the smallest measurement size.
Then continue to measure the frame height. You do this from above the threshold to the head of the jaw under 3 places – in the top, middle and right. Here you will also write the smallest size. Take diagonal measurements from one corner to another and make sure both dimensions are the same. If the frame is not square, adjustments need to be made. You need an angle meter to find the slope of the threshold.
