4. Adjustment the windows
There are four ways of adjusting windows:
- Diagonal casement adjustment
- Parallel horizontal adjustment
- Parallel vertical adjustment
- Contact pressure adjustment
When adjusting new windows, all of these steps should be taken. However, if a window has warped over time, you may only need to take one of these steps, based on how your window is malfunctioning. The actual adjustment process can be divided into two different types of steps – must-do steps and those that depend on the malfunction.
There are a number of steps which will have to be performed no matter what.
- First, identify the problem. Is it jamming, is a draft coming through – and where are the problems occurring?
- Measure the space between casement and frame for later adjustment. In particular, measure the distances on both the side where the window is jamming or the draft is coming from, as well as the opposite side. For example, If the jam is occurring on the left side of the frame, you should to measure the distance between casement and frame on the left as well as on the right-hand side.
- Remove the covering caps from the stay arm and lower corner bearings, located on the hinge side. This exposes the adjusting screws which are necessary for the following steps.
