Double Glazing Unit Repair If you have double-glazed windows that appears cloudy or misty and cannot be cleaned it's likely to have been "blown". This happens when the space between the window panes is widened due to the degrading of the window seals. Replacing the gasket seals on your windows can fix this problem and is cheaper than replacing the whole double glazed unit. Seals The window seal (also called the window gasket) is responsible for sealing the air between the two panes of your double-glazed windows. This prevents cold drafts from entering your home as well as stopping condensation and moisture from building up in the space between the panes of glass. Over time, this seal will deteriorate due to the rapid changes in temperature throughout the year, which causes it to shrink and eventually pull away from the frame. Replacing your window seals is an inexpensive and efficient way to repair your double glazing units. The most common sign that your window seals have gone down is condensation that forms between the two panes of glass in a double glazed window. This is caused by the accumulation of humidity inside the home. The excess moisture can't escape through the glass, therefore it cools down and condenses on the windows' surface pane. This can cause windows to become cloudy and obscure your view from the window. Condensation may also settle on the outside of window frames when windows mist. This can damage the timber frames, as it could cause rot to them and leave you with a damp house. Repairing a window that is leaking moisture early could save you a significant amount of money, stop damage to your house and protect your health as the excessive moisture in your home can cause respiratory problems, allergies and asthma. To fix a window which has a broken seal, the first thing you have to do is clean the glass and edges of the panes with cleaning fluid and a sponge. This is to ensure that the surface of the glass is clean and free of dirt and grime before applying the new sealant. After you have cleaned the glass, you can then seal the window again using a suitable solvent based sealant. Before starting, ensure that your workspace is ventilated. After your workspace is free of dust, carefully remove the black sealant along the edges of the sealed unit. This will break the spacer bars made of silver and the glass panes. Once you have separated the two using a sharp knife, use it to cut into the remaining sealant, and then remove as much as you can. Then scrape off any other remnants with a scraper. Glass Double-glazed windows consist of two panes of insulated glass, separated by a spacer to create gaps. The edges are then sealed. This makes the windows airtight and also stops moisture from entering into your home. Glass is available in a variety of designs as well as tints and thicknesses. There are also acoustic and Low-E glass options. If your double glazing is experiencing a problem such as fogging or condensation, it is due to an issue with the seals. As time passes, these become brittle and small holes begin to form in the sealing around the edges of the glass unit. When these begin to appear, the moisture could seep into your home which will cause damage to the surrounding area such as damp, rot, and mould. To fix this you will have to remove the affected window pane and the frame of the sash. Once the pane is removed, clean the frame of the sash to remove any dampness or rot and then thoroughly clean both sides of the glass unit, removing marks and smears. After cleaning, it is possible to cut the glass unit from the spacer bar. When splitting the glass, be careful not to cut through the unit's back or spacer bar. It is also recommended to use a second pair of hands to hold the unit in place while you work. Once the glass has been split carefully, you must remove the beads and scrape away any remaining sealant. You will have to replace it with a high quality top-grade glazing sealant. The sealant you choose must be water-proof and thermally resistant, as well as securing the two panes.
