How to Repair Double Glazed Window Repairing double-glazed windows is a major challenge, especially for those who are not window specialists. There are a few options to consider if you are willing to take on a more difficult DIY project than just taping cracks. Misting is often a result of the special packaging that keeps the glass sheets in place is worn. This is typically corrected by an expert. Cracks It is normal to install double-glazed windows in homes to reduce energy bills. It works well. If there is cracks, air can escape from the glass which can make your home uncomfortable. The issue isn't permanent and there are a variety of solutions to fix it. If you notice cracks in your window, it's a sign that the seal has burst. This means that all of the gas that acts as an insulator between the two panes has gone away, which can be costly for homeowners as it will reduce the efficiency of their home. Repairing the crack is crucial to avoid future problems. It can also be an opportunity to upgrade your windows. Cracks that are common in double-glazed windows are caused by thermal stress. This can occur when there are sudden temperature fluctuations, such as when radiators are turned on and a burst of heat is sent to the insulated space between the window frame and the wall. Cracks may also appear on your windows due to seasonal influences like sudden temperature changes overnight. Poor installation is another common cause of double-glazed windows cracks. If the space between the glass panes is not sufficient or the frames are poorly fitted, it may cause the glass to expand at different rates, which can lead to cracks that develop over time. This is a problem that can be avoided by choosing the right fitter for your new double glazing and checking customer reviews/testimonials. A double-glazed window that is cracked should be repaired immediately to prevent further damage. This will protect both the frame and the glass. A professional glazier will be able to provide you with the best repair method for your specific situation. This could involve filling in the cracks using a type of putty or adhesive which will stop the cracks from growing further or breaking completely. Condensation If you see visible condensation, it is an indication that the double-glazed window needs to be replaced or repaired. It's recommended to inquire with the company you purchased the windows from to see whether they have a warranty that covers this type of issue. Condensation occurs in double-glazed windows when the seal breaks, and the insulating gases between the glass panes aren't kept in. This is usually caused by air movement or changes in humidity in the room, and can be very uncomfortable. Fortunately, the gasket seals are able to be replaced without the need to replace the entire window unit. This is usually done by drilling a tiny hole in the glass and filling it up with desiccant. Then, it's re-sealed using an entirely new gasket to prevent the moisture from re-entering. However this method of removing condensation is only temporary, and it's unlikely to prevent condensation from forming in the future. It's also not as efficient as replacing windows. It's important to know that condensation on the outside of double-glazed windows can be an excellent thing. This kind of condensation occurs when the air is warmer than the window and is a natural part of the process of maximizing thermal efficiency. If you notice condensation between the double glazing panes it is a sign that the seal has been damaged and the windows require to be replaced. There are several ways to prevent condensation in the windows that are double glazed. Firstly, it's a good idea to open the window or make use of an extractor fan while cooking or showering. It's also a good idea to add some shade to the area around your window. This will help to keep the glass warm and limit condensation, which can reduce your energy efficiency. Also, it's a good idea to wipe the frames down with a damp cloth from time time to get rid of any dirt and grime that may cause issues. It is possible to spray the frames with a rust inhibitor to shield them from oxidation. Broken Seals A leaky seal could cause your double pane windows to have gaps between the two panes. This can result in an increase in your energy bill as hot air can escape and cool air can get in. In some instances, moisture can seep into the home and cause mold and mildew. Fortunately, there are many alternatives to repair the damage if your window seals have failed. You can employ an expert window technician to remove the damaged glass and reintroduce argon gas or krypton gas into the void between the two windows. These gases are an inert, odorless, and clear gas that can function as an insulator and aid to keep heat inside during the winter and out in the summer. This alternative is more complicated however it could be the most cost effective long-term solution to your window. A professional will have to remove the frame from the window in order to identify and repair any cracks and gaps, replace the glass pane clean the frame and then reassemble the frame. The most common reason for window seals to break is due to age and exposure to the elements. As seals age they become less flexible and eventually break. Exposure to extreme temperatures can cause seals to weaken over time. This is especially relevant if the glass was not cleaned regularly, which can leave deposits that interfere with the seal's flexibility. One of the most obvious indicators that your window seals aren't working is the appearance of condensation between the glass or a hazy appearance. This happens when window seals let humid air get through, and then cools and condenses. This can happen regularly and is exacerbated by changes in weather and outdoor humidity levels. Examining the seals on your windows frequently and making any needed minor repairs is the best way to prevent this. This will not only lower your energy bills but also ensure that your windows are in good shape for longer. Replacement The insulation properties of double glazed windows aren't just great to conserve energy in your home; they can also enhance the value of it. Estate agents agree that properties with double-glazed windows that are in good condition will increase in value. Maintaining your windows to ensure that they are performing is crucial for the longevity and value of your home. Double-glazed windows are composed of two panes separated by a gap, which is typically filled with an insulating gas, such as Krypton or argon. These gaps can leak and cause condensation if damaged or broken. This means your window isn't insulate your home properly, leading to higher energy costs. The presence of moisture between the panes of double-glazed windows is typically caused by an air leak or a damaged seal, which means that it's time to replace the window unit. It's expensive to replace the entire window, however it is usually worth it when you consider how much your energy bills will be reduced by having windows that are more energy efficient. It is dangerous to handle broken glass. Before you can remove the IGU it is necessary to remove the silicone or molding around the window frame, as well the wedge gasket. After you have removed the IGU, you'll have to apply a new sealant to the frames. As well as preventing draughts and helping to preserve your energy bills, double glazing also helps to reduce the noise pollution that comes from outside. The additional layer of air and glass will make it far more difficult for a burglar to gain entry into your home, which is particularly beneficial for those who lives near a busy street or airport, or has noisy neighbors. Double-glazed windows also keep your home cool during summer and warmer during winter. It's not surprising that double-glazed windows are so popular with homeowners in the UK.
