![]() Repairing the seal is difficult and expensive. A double-glazed window with a broken seal will still function better than a single-paned window, but it won’t be anywhere near as insulating as a window with an intact seal. If your guarantee has expired, you have a decision to make. The window has failed, and they’re obliged to correct it. If your window’s still under the manufacturer’s guarantee, you’ll want to get it replaced straight away. This doesn’t just, of course, mean that you’ll need to put up with more condensation blocking your view of the outside world it also means that your window will be far less energy-efficient. The more condensation inside the window, the greater the degree to which the seals have failed. So what does all this mean for windows in which condensation has formed? Simply put, it means that the seal which safeguards the interior of the window has broken, and airborne moisture from outside has found its way in. These balls act as a desiccant they’ll absorb small amounts of moisture, and prevent condensation from forming. In order to deal with any moisture that might get trapped between the panes during sealing, window manufacturers would use silica balls the sort that you find shipped alongside electronic equipment. When an inert gas like argon or xenon is used inside the cavity, the flow of heat is reduced even further. By sandwiching a layer of air between two panes of glass, we can slow the transfer of heat from one side to the other considerably. ![]() ![]() How does double glazing work?ĭouble glazing makes a significant difference to the energy-efficiency of a building. This is normal (although you may want to take steps to reduce the amount of moisture in your home). Condensation that forms between the panes, however, is evidence of something a great deal more concerning. As the airborne moisture comes into contact with a cold window pane it condenses. A steamed-up window is quite a common sight in modern homes – particularly if it’s cold outside and you’ve got the heating cranked up.
