On the other hand, if your uPVC window sash doesn’t quite contact the window frame when shut, but rests about 1⁄16 inch (0. 16 cm) above them, you’ll need to lower the window’s height. A window “sash” is the panel—typically made of multiple glass panes—which raises and lowers to open the window.
Since adjusting the window may take 15-20 minutes, plan to do it on a rain-free day.
The casement of a uPVC window is the metal strip which fastens directly to the wooden window frame. The hinges which allow the window to be opened and shut also attach to the casement. When adjusting the window’s height, do not loosen the screws holding the hinges to the frame.
All 8 of the screws holding the window sash to the casement will most likely take a large Phillips head screwdriver. If this doesn’t fit, test out different sizes of Phillips head until you find one that fits snugly into the screw.
You may need to support the weight of the window panel until the screws have been tightened again. If the panel is very heavy, it may be pulled downward under its own weight.
At this point, your uPVC window should fit snugly into the frame when closed. [6] X Research source This will also stop any drafts that have been coming into your home through the unaligned window.
Adjusting the position of the lock will help your window seal properly if the locked window has been lose and drafty or if the lock mechanism doesn’t quite catch and seal the window properly. This style of window is called a “long-bottom lock,” and the part that lets you adjust the lock’s position is called the “head. ”
If you don’t already own Allen wrenches, you can purchase a set of them at a local hardware store.
Turning the wrench counterclockwise will relax the pressure when the window is shut. Try this approach if your window hasn’t been locking fully, or requires a great deal of force to lock.
