Why You Need to Adjust uPVC Windows – From Experts at Window Replacement Parts and Repairs
Although uPVC windows are designed to be low maintenance, they still need care. Everyday use can gradually loosen the screws. Additionally, uPVC’s special property of thermal efficiency means they can be prone to expansion and contraction during the warmer and colder seasons. This is especially true for double glazed windows because of their thermal qualities. This make it essential to regularly maintain your windows to ensure they are functioning at their fullest.
You may notice your uPVC window needs adjustment if you feel a draught through the window. Alternatively, if you begin to struggle to open and close the window, it may be a sign that an adjustment is required.
Regular adjustments are important for a variety of reasons:
- Maintain uPVC’s energy efficient properties
- Difficult to open windows pose a potential fire hazard
- Difficult to close windows can be a security risk
- Prevent strain on the window mechanism, helping the window last longer
- Help ensure the window lock mechanism is functional
How to Adjust uPVC Windows
Fortunately, it is easy to learn how to adjust your windows. This can usually be done using a screwdriver or an Allen key. Before you begin, it is recommended to clean the window frame and window hinges of dirt and debris. You should also take the opportunity to spray the screws with a light lubricant to keep everything moving smoothly and prevent rusting.
Window Type
It’s important to remember that the location of adjustment screws can vary depending on the type of window you have. Open your window fully and make sure you locate all the adjustment points before beginning the job. If any screw is missing or damaged, it will require corrections. Typically:
uPVC Casement Windows: Adjustment screws are usually located on the hinge side of the frame, most often on the hinge bearings. These screws should be at the corner or on the metal stay arm. This allows the window sash to swing outwards and control the alignment.
uPVC Tilt and Turn: Adjustment screws are usually located on the window hinge and stay arms, usually located at the top and bottom of the sash. They sometimes might be hidden under plastic covers. Slide the cover up to reveal the adjustment mechanisms.
uPVC Sliding Windows: These don’t use side hinges but instead run on tracks. Adjustments are typically done by turning small screws at the bottom of the sash, which raise or lower the rollers to make the window slide smoothly.
Adjusting uPVC Window Hinges
To adjust the window hinges, open the window fully and locate the adjustment screws. There are multiple points on the window. The three main types of adjustment screws you should be aware of are:
Height Adjustment Screw: Turning your Allen key or screwdriver clockwise should raise the window upwards in position, whereas anticlockwise should lower the window down. This adjustment is important for windows that are catching at the top or bottom of the frame.
Lateral (or Horizontal) Adjustment Screw: Turning your Allen key or screwdriver will move the window horizontally in position, closer or further away from the window frame. This adjustment screw is often located on the side of the window hinge. This adjustment is important for windows that have a misaligned sash or gaps.
Compression Adjustment: Turning your screwdriver of Allen Key will tighten or loosen the windows seal against the frame. This is important for windows which experience draughts as it improves insulation. For tilt and turn and casement windows, roller cams should control compression adjustment.
When making adjustments, open the window completely so you have full access to the screws. Aim to loosen or tighten the screws with quarter turns. This prevents the mechanism from becoming over-tightened or too loose, which can cause damage. After each adjustment, open or close your window to check the movement before making more changes.
