2. Seals

The window seal is a crucial component of double glazing. It is essential to keep your home safe and energy efficient, as well as draught free. The seal is located on the inner perimeter of the uPVC frame and creates an air-tight seal over the gas-filled space between the two panes of glass that make up the window. This is a crucial part of the insulative effect the double glazing provides and any problems or failures in the seals could substantially diminish this benefit.

However, this can be an interim fix and a plug has to be placed in the hole in order to keep it shut.

3. Locking Mechanisms

Double-glazed windows have gaps of air between the glass panes to protect against the fluctuating temperatures outside and to help keep the heat inside the home. This type of window can also be called an insulation unit (IGU). They can offer you a lot of energy efficiency that can save on your heating expenses.

The seal could be blown when you can't open your double-glazed window, or if there appears to be a misty area between the panes. This could occur if the frame of the window moves slightly, or if the packing that keeps the glass sheets in place deteriorates over time.

There are a variety of ways you can repair a double glazed window by yourself, but it's generally better to hire a professional company. You should always follow the directions of the manufacturer and make use of the appropriate tools. It is also worth bearing in your mind that if you try to remove the glass yourself then you'll lose any guarantee you might have and you could end up paying a higher cost than if simply contacted the company from whom you bought your windows.

Once the damaged pane is removed, you can replace it with plastic spacers to make sure it fits in the frame and add any necessary uPVC beading. After that, you can install an additional wedge gasket and lock the window in place.

4. Weatherproofing

There are solutions to fix double glazing windows that are hard to open or have become sagging. For instance, you can try oiling the hinges, mechanisms or handles to see if this can help. You can also change gaskets to boost your windows' performance and stop them from opening up to cold air and drafts. You can get these from a hardware store or on the internet and they are easy to install. If you do not have the time to do it yourself, you can hire a professional to complete the task for you.

Condensation between window panes is another issue that is easily fixed. This is usually caused by a broken seal, which will allow moisture to get in the gap between the glass panes. This can cause mist to form on the glass, which is unattractive and ineffective.
