How to Repair Double Glazed Windows
Many homes with double-glazing encounter issues like condensation, decrease in the quality insulation and windows that are difficult to open. These problems are typically a result of a defect in the hinges, mechanisms or handles.
You can repair these windows with a few easy steps.
Cracked Panes
If a double-pane windows is damaged, it's an urgent issue that must be dealt with promptly. Double- and triple-pane windows are insulated using gases that keep warm air in the winter and cold air out. So, when one of the panes cracks this gas escapes and your home is less well-insulated. Cracks can also get worse over time. Making them repairable now can prevent a more serious problem in the near future.
If a crack develops the most important thing is to identify what caused it. It's possible that a collision or structural problem caused the crack. In this case it is crucial to inspect your other windows for damage to determine the next steps.
It is also a good idea to inspect the area around your home for any other problems that could be causing the crack. For instance, if your windows are located near to other doors and walls, the stress of expansion and contraction caused by temperature changes may be causing the cracking.
There are many ways to repair a crack depending on the source. For instance, if the crack was caused by an impact, you might be able to work with replacing just the broken glass. It is possible to replace the whole window frame. This is a more difficult solution that requires expert assistance.
However, if you're facing a crack that didn't cause the frame move, it's normally simple to put an adhesive between the damaged panes. This fixes the fracture and protects your window from any further issues It's definitely worth trying in this instance.
Another option that's fairly simple is to cover the crack with clear tape. This isn't the best look, but it will prevent drafts and bugs from getting into your home. The next step is a glass repair film that's designed to be applied quickly and offers greater protection. This is available from many double glazing companies and is worth the investment to safeguard your windows.
Condensation Build-Up
Double glazing windows needing to be repaired are usually because of condensation between the panes. It is usually a sign that the seal between two window panes was not strong enough, allowing water to enter. This can lead to condensation and other problems which may require replacement of the window.
Double glazing is more effective at decreasing condensation than single pane windows as it has a space between the glass which is filled with air or gas that is not toxic. 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 instances the spacer bar has silica gel which is effective in preventing moisture from getting between the glass panes.
This is the reason it is essential to clean your windows regularly and keep them clean since this will reduce the amount of condensation that forms and allow it to evaporate. Using extractor fans or opening the windows to increase air flow can also aid in removing excess moisture.
Installing a dehumidifier can be another way to combat condensation. These units are available for between PS60 and PS150. They are an excellent investment that will not only stop mold growth, but also reduces condensation.
Condensation between the glass panes of your double-glazing can occur due to the fact that the outer air is colder than that of the inner window pane, which causes the surface to cool and form condensation. It can also happen when you experience changes in temperature, like turning on the heating or cooling of your home.
Unfortunately, condensation can also be a sign of a poor double glazing design as some of the older models are constructed with rubber strips instead of the more modern silicone version, which can deteriorate over time. In certain cases it's possible to have your seals repaired, although it is important to remember that this will only offer a short term solution as the window will eventually fail in another area, meaning you'll need to replace it in the future.
Stained Glass
If you're having trouble with a double glazed window handle or lock it is possible to repair it instead of having to replace the entire glass pane. However, this is not always a DIY project since specific tools are required to ensure that the repair is done correctly and doesn't compromise the seal or the purpose of the window.
The most common complaint of double glazing owners is that their windows or doors have become difficult to open and close. This is usually due to some slight warping of the frame or hinges, but it could also be due to issues with the sealing. It could be that the issue is more than that and you should talk to a professional to discuss the options.
Another issue that is frequently reported is the forming of condensation between glass panes. This could be an indication of a leaky seal that isn't retaining the insulating gases between the glass panes. This is an easy fix. The insulating gas is restored with special glue to fill the gap.
Start by placing the broken window on a flat work surface. Carefully peel back the black sealant to expose the silver spacer bar and cut into this using a sharp knife, making sure to stay below the base of the glass and the silver spacer bar. Cut until you are able to separate the two pieces and after you've done this, put the top layer of glass on your work surface (it is best to wear gloves while working). Clean both the glazed surface that is facing into the frame and the spacer frame, taking particular care to remove any marks or smears since these can impact on the seal when the window is reassembled. Then, put the new spacer bar on the glass pane and apply adhesive along its edges to ensure it bonds with the glass and the silver spacer frame. Allow window frame maintenance to dry before reassembling. It is recommended that two people help you as it can be difficult to get everything aligned.
Gasket Seals
Double glazing is designed to last for years however, there are some issues that may arise. It is important to fix any issues immediately when they arise regardless of whether it's draughts or problems with opening and closing.
One of the most frequent problems faced by double-glazed owners is condensation forming between the two glass panes. This is caused by the failure of the desiccant, which absorbs moisture from the air inside the space that is insulated. Once the desiccant has failed the condensation can form within minutes and form a dark line across the windows.
Another issue could arise if the gasket seal is not able to stop water and other pollutants from entering the insulated gap. This can cause leaks around the edges of the frame, and can also damage the surface of the double glazed unit itself. Contact your installer immediately if you notice any signs that your double-glazed units are leaking.
A lot of companies offer a warranty for their products. These warranties usually include a period of guarantee of 10, or even 20 years. Some companies even offer lifetime warranties. Review the terms of your warranty to determine what is covered and how long it lasts.
It might be worthwhile trying to solve any hardware issues yourself before calling your double glazing provider for repairs. For instance, you could try cooling the mechanism or oiling it to see if it resolves the issue. Alternatively, you can try removing the handle or window handle and cleaning it prior to placing it back in the correct position.
Check with your local council to see if they offer any grants to assist you in the replacement or repair of your double-glazed windows. There are many different methods to apply and certain areas will require a particular form of application or proof of eligibility, therefore it is always worth checking with your local authority prior to deciding on how to proceed.
