Clean and dry the inside of both panes of glass thoroughly.Optionally, you can also cut the seal against the other pane of glass to remove the spacers entirely. Cut the seal against one of the panes of glass, using a utility knife.

Remove the IGU from the frame, and lay it down on a workbench.There is also a more difficult method that is definitely only for the handiest of handymen, but that might give a longer-lasting result. When it has dried completely, cover the holes with clear industrial packaging tape, or use a waterproof sealant.Once all the dirt on the inside has been removed, allow the window to dry.Collect the drained window cleaner from the bottom tube in a bucket or bottle. Move the direction of the tube around to reach the entire inner surface of the glass. Attach a funnel to the top tube, and pour window cleaner into it.The top tube should be able to reach the middle of the IGU. Insert a piece of plastic tube into each of the holes.If you don’t have a drill, read our cordless drill reviews to find the best one for your home. Cool the drill bit in a cup of water when it gets hot. Drill two holes on the inside corners of the window, one on the top, and the other one diagonally opposite at the bottom.You can fix the problem with a few simple tools and household cleaners, but there are also several commercially available cleaning kits. Going this route is a compromise between the other two options, since you will have clear windows, but lower thermal insulation. If you don’t want to replace the IGU yet, for whatever reason, there are some things you can do to try and clean it yourself. This is also the best option, since you will have a brand new, crystal clear IGU, and better thermal insulation to boot. This can be fairly costly, unless the failed IGU is still under warranty.

This saturation, in turn, happens when the seals that are supposed to keep moisture out and the inert gas in, is no longer doing its job.Īt first there may be only a bit of condensation, which may or may not disappear after a while. A bit of condensation in between the panes of glass is usually an indication that the desiccant is saturated. By the time they start showing signs of fogging up, their seals are probably already ruptured. There is very little you can do to prevent foggy windows. Obviously the cost would be higher for longer warranties, but the higher cost will be entirely justified in areas with huge temperature differences between summer and winter. IGUs with longer warranties, in the 20 year range, will be less likely to fail early than those with shorter warranties. IGUs usually have a lifespan of 10-25 years before they start fogging up. The size of this gap is the biggest factor that determines the degree of insulation that the panel would provide. The gap in between the panes of glass is usually filled with an inert gas, such as krypton or argon, which is a poor conductor of heat. The spacers are often filled with a desiccant that absorbs condensation.

They consist of two panes of glass separated by spacers, and sealed around the edges. Double pane windows consist of a window frame and an Insulated Glass Unit (IGU).
