Double glazing condensation can be unattractive but it does not necessarily mean that you need to replace your windows. Most of the time, a brand new sealed unit is all that's needed. Double glazing is filled with Argon gas between the two window panes which helps control the temperature and insulation within your home. If it is damaged, it can cause misting windows and a loss of performance. Repair Double glazing is an excellent energy-efficient solution for windows, however, when window seals begin to degrade, it allows moisture to enter, causing condensation and mist. If this occurs the windows won't perform as they should and your home will lose heat, which results in a higher cost for heating. There are many solutions to this issue, including repair or replacement. Double-glazing's effectiveness is due to the structure of its two glass panes, separated by a thermally efficient spacer bar. The spacer bar and the air or gas inside it form an insulating layer that keeps warm air and blocks colder air. If this arrangement fails, and the window panes become misty, the glass or seals are usually damaged. The seal may break due to various reasons, but normal wear and tear is the most frequent. When temperatures change, the seal expands and contracts which puts pressure on it over time until it eventually breaks. This is a common problem with older double-glazed windows however, the seal could fail due to issues with installation or excessive use of cleaning products. If you notice that your double-glazed windows are leaking then it's time to seek out help. This problem can be difficult to solve on your own, which is why it is essential to engage an expert who can replace or repair the unit that is sealed and restore its performance. Select a contractor who has a good track record and offers warranties on their work.
