How to Repair Double Glazed Windows
Many properties with double-glazing experience issues with condensation, a decrease in the quality insulation and windows that are difficult to open. These issues are usually the result of a defect in the hinges, mechanisms or handles.
You can fix these windows in a couple of easy steps.
Cracked Panes
A double-paned windows that are cracked is a serious issue that needs to be addressed immediately. If a double- or triple-pane window cracks the gas that seals it will keep out cold air and warm air in winter escapes. This means that your home is less well-insulated. Cracks also worsen over time, so fixing them now prevents a potentially more serious issue in the future.
The most important step to take when a crack appears is to determine the cause of it. It's possible that a collision or structural issue caused the crack. In this case, it is important to inspect your other windows for damage in order to determine the next steps.
It is also recommended to check the area around your home for any other problems that could be contributing to the crack. For instance, if your windows are situated near walls or doors, the stress of expansion and contraction caused by temperature changes may be causing the cracking.
There are many ways to fix a crack depending on the source. For example, if it was caused by an impact, you might be able to do away by replacing only the damaged glass. Alternatively, you might need to replace the entire window frame. This is a more complex solution that requires the assistance of a professional.
If you have cracks in your glass that did not cause the frame to shift, then it's generally easy to apply adhesive between the damaged panes. This will fix the crack and prevent further damage to your window.
Another option that is fairly easy is to cover the crack with clear tape. This doesn't offer the best appearance, but it does prevent drafts and bugs from getting into your home. The next step is a glass repair film that's made to be easily applied and provides more robust protection. Many double glazing companies provide this service, which is worth the investment to protect your windows.
Condensation Build-Up
Condensation build-up between the panes of double-glazing is one of the most common reasons why people have to fix their windows. This is because it indicates that the seal between the panes of glass has been breached which allows water vapour to enter. This can lead to condensation, as well as other issues that could require replacement of the window.
Double glazing reduces condensation better than single panes of glass due to the fact that it has a space in between the two panes that is either filled up with non-toxic gases or air. The space between the glass and the window frame is separated by a spacer, which acts as insulator. This helps to prevent heat loss. In many cases the spacer bar is made up of silica gel which is effective in preventing moisture from entering between the glass panes.
It is therefore crucial to clean and regularly clean your windows. This will reduce the amount of moisture that accumulates and let it evaporate. Extraction fans and opening windows can help eliminate excess moisture.
Installing a dehumidifier is another way to combat condensation. These units are available for purchase at between PS60 and PS150. They are a wise investment that will not only reduce condensation but prevent mould growth within your home, too.
Condensation between the glass panes of your double glazing may happen because the air outside is colder than repair upvc windows the inside window pane, which causes the surface to cool down and form condensation. It can occur when you alter the temperature of your home, for example by turning off or on the heating.
However, condensation could also be an indication of poor double glazing construction since some older models are constructed with rubber strips instead of the more modern silicone version that can degrade over time. It may be possible to repair your seals, however this is only a temporary solution because the window will eventually fail in a different location.
Stained Glass
If you have a problem with a double glazed window handle or lock it is often possible to repair it rather than having to replace the entire glass pane. This is not a simple DIY project, as you'll require specialized tools to ensure that the repair is done right.
The most common complaint of owners of double glazing is that their windows or doors have become difficult to open and close. This is typically caused by some slight warping of the frame or the hinges, but could also be due to problems with the sealing. In certain cases, the issue could be more serious and it is worth speaking to a professional regarding the options available.
Another frequent complaint is the formation of condensation between the glass panes. This can be a sign that the seal is failing and no longer holding in the insulating gas between the panes. This is a simple fix. The gas that is insulating is restored with a special glue to seal the gap.
Start by placing the faulty window on a flat surface. Remove the black sealant to reveal the silver spacer bar. cut into it with a sharp blade, making sure to stay below the glass's base and silver spacer bar. After you have separated the two pieces, put the top glass pane on your work surface. It is best to use gloves for this step. Once again thoroughly clean both the glazed face that is facing into the frame and the spacer frame, taking particular care to remove any marks or smears as they could affect the seal when the window is re-assembled. And lastly, place the new spacer on the glass pane. Spread the adhesive along the edge to help it adhere to the glass and silver frame. Allow the adhesive to dry before reassembling. It is recommended to have two people help you because it is difficult to get everything aligned.
Gasket Seals
While double glazing is durable and designed to last for years to be, there are problems that may arise at times. From draughts to issues in closing or opening it is essential to address any problems quickly to prevent them from becoming worse.
One of the most frequent issues reported by double-glazed owners is condensation forming between the two glass panes. This is typically caused by a failure of the desiccant, which absorbs moisture from the air within the insulated gap. Once the desiccant fails, condensation can form in minutes and create a dark line on the window.
Another issue that could arise is when the gasket seal is not able to keep water and other contaminants from the gap between the insulated gaps. This could cause leaks around the edges of the frame and also damage the surface. Contact your installer right away if you observe any indications that your double-glazed units are leaky.
Many companies will provide a warranty for their products, and they usually come with a guarantee period of either 10 or 20 years, and some even provide lifetime guarantees. Review the terms of your warranty to determine what's covered and the length of time it will last.
You may want to try and solve any hardware issues yourself before contacting a double glazing supplier. For instance, you could, try cooling or lubricating the mechanism to determine if that fixes the problem. Alternatively, you can try removing the handle or window handle and cleaning it prior to returning it to its place.
Check with your local council to find out whether they have any grants to aid in the replacement or repair of your double-glazed windows. There are many different ways to apply and some areas will require a certain form of application or proof of eligibility, so it is always worth checking with your local authority prior to deciding on how to proceed.
