Double glazing refers to panes of glass within the frame of a window or wall opening. This window glazing can be damaged and require repairs.
If you've noticed condensation between your windows, or a noticeable draft, or if hinges or handles become difficult to open, this could be an indication that your double glazing requires repair. This repair typically involves a reseal on the entire unit.
Broken Panes
Double glazed windows consist of two glass panes with an air gap in between that is filled with inert gases, such as Krypton or argon. This keeps heat in your home and prevents cold drafts from getting in. Sometimes windows get damaged and when this happens the entire window may need replacement. It is essential to call the company that sold you the double glazing when you notice cracks or chips appearing in the window.
A few easy steps can be followed to repair a broken window pane, but it is not recommended that you attempt repairs on your own unless you're a skilled DIYer. First you'll require gloves and remove the broken pane. If it's cracked, apply strips of masking tape over the cracks in a crisscrossing pattern. This will prevent the cracks from becoming worse as time passes, especially in the winter. It is also recommended to cover your work surface in newspapers to prevent any broken pieces from falling. Once the damaged pane has been removed scrape off any glazing putty or glazed window seal using the help of a knife. Remove the glazing points with pliers. Then, you can coat the unfinished wood with a fast-drying primer.
Measure the length and the width of the grooved channels using a tape. Subtract 1/8" from both measurements to allow for the slight movement of the replacement pane. Then, slide the replacement pane into position and roll thin pieces of glazing compound into the grooved channels. Tap the glass gently using the hammer every 6" or 8" to aid in setting it in its place. Be careful not to break it.
If you have a double glazing warranty, it's worth trying to use this to avoid the cost of a full replacement window. Generally the warranty will cover the cost of any component that you might require replacement, as well as labour. It is crucial to review the details of your guarantee as they will differ from one company to another so be sure to are aware of what is covered and when.
Foggy Glass
Condensation between the panes of your double glazing could cause foggy glass. This can be caused by a variety of factors, including fluctuations in temperature, when the frames aren't set correctly, and even ageing of the seals themselves.
In most cases, double glazing installers are able to fix this issue quickly and easily. You should contact the company that installed your windows as soon as you notice any problems. Follow up with a written response. This will make it easier if you need to contact them in the future. It can also prove extremely useful if the problem is covered under your warranty or guarantee.
It is possible to fix the problem by replacing the gasket seals. This won't need replacing your entire window unit. It will help keep your home more energy efficient. The window glazier should first remove any clips or retaining strips that hold the IGU and then make use of a saw to cut away the old sealant.
Then they will build or order an IGU replacement to fit the frame and use special sealants in order to ensure that it is airand water-tight. Once they're finished installing the retaining clips or strips and seal it with more to ensure it's secure.
If you're lucky, the misting will stop after this. It's important that your frames are ventilated properly to prevent moisture from accumulating within your ceilings or walls.
Another frequent issue that double glazing owners have reported is that their windows or doors become difficult to close and open This could be the result of extreme weather, or it could be that the frame has dropped or sagged a bit over time, and isn't at a level with the rest of your home. If this is the problem then you could try wiping down the frames using cold water to shrink them slightly. However, this won't solve the issue completely. If you're unable to resolve the problem, you may need to hire a professional to replace the frames.
Condensation
Condensation occurs when the insulation gases in double-glazed windows do not hold their place, leaving moisture and air between the panes. This is a frequent issue in winter, when humidity levels are typically higher, though it can happen at other times of the year too. A build-up of moisture can cause mildew and mould around sills, sealants and window frames which are not only ugly but also harmful to your health. The good part is that condensation can frequently be resealed by a window expert to reduce the moisture level in your home and stop moisture from accumulating.
Window sealing, or window gaskets, are an essential component of any double-glazed door or window. They help seal in the air that is insulated between the window glass and stop drafts, heat, and moisture from entering your home. The gaskets may perish or shrink over time due to temperature fluctuations, weather conditions and aging, meaning that you might notice condensation appearing on your double-glazed windows or doors.
This can be repaired however, it will require replacing the "sandwich" (thermo-pane & glass) inside your double-glazing window. Unless you have the right tools for the job it is recommended that you hire a professional to re-seal your double-glazed windows.
Another frequent issue is mist between double-glazed windows. This can be difficult to resolve. This indicates that the factory vacuum seal has failed, and there is no way to let air into or out of the sandwich.
A professional will reseal the windows by using the same procedure they would with fog or condensation issues. This usually involves removing the thermo-pane sandwich, spraying it with a cleaning solution and then sucking out the old sealant. It is crucial to precisely measure the sandwich's length, width and thickness so that the replacement will be a perfect fit, and a new seal can be drawn between the glass.
This is a difficult job that requires tools not typically found in DIY stores. It's best to leave it to professionals because faulty seals can lead to mold and damp within your home, which could be expensive and harmful to your health.
Water Leaks
If you see water leaking around your double glazing windows it's important to act fast. The smallest leak can become a major issue if not addressed quickly.
The window frame can be the culprit. Check that the sill pan which is the flat base of the window frame, is pitched so that water is able to drain away from your home and not into the frame. If you notice that the sill pan is not properly pitched or you see water in the wood, you should consult an expert in double-glazing repair.
Another common cause of water leaks is damaged window seals. This could be due to weather, age, or damage. This isn't an easy thing to fix and is typically best left to the experts.This could lead to an increase in energy efficiency. This can also allow cold air to enter your home in the winter, and hot air to escape during summer. This can lead you to costly cooling and heating costs.
The simplest solution is to apply a fresh layer of caulking. Although those who have DIY skills can do this themselves however, it is more efficient to have a double-glazing specialist handle the task. You'll be able to rest assured and have a guarantee that the job was done properly.
Some double-glazing windows come with warranties of up to 20 years. It is a good idea to check with the company you bought windows from and find out what they cover and for how long. This will save you the expense of having to replace your double-glazed windows at a later time. If your double-glazed windows are covered under a warranty, it is important to register the problem as soon as you notice any issues. You can do this online or by contacting them directly. This information is useful in the event that you have to utilize the warranty.
