Double glazing condensation?
Our Expert Answer...
We are often asked about double glazing steaming up. With double glazing there are three types of condensation.
- On the inside of your windows (in your room). In other words you can run your finger down it and your finger gets wet. This is unlikely to be as a result of a faulty or failed glazing unit. This occurs when moisture in the air hits the coolest part of your homes (usually your windows). More likely you have an abundant source of moisture in your house such as: washing drying on radiators, steamy kitchen/bathroom, failed damp proof course, roof damage, guttering damage, a serious ground water problem. If you are seeing this kind of condensation on the inside of your old windows then speak with your local Safestyle double glazing advisor to confirm if the old windows are failing, or if you need to speak with a good quality builder about the excess moisture in your home.
- Condensation can appear between the two sheets of glass in your old double glazing unit. This is a sign that the glazing unit has failed and should only ever occur in an old unit – although low quality double glazing can often fail early. The reason condensation is appearing is because the seal trapping air between the two double glazing panes has broken allowing normal air to pass in and out. This air contains moisture which condenses within the frame. If this has happened to your windows you should speak with Safestyle immediately to get an emergency replacement quote. Or you can ask for one online.
- Finally there is external window condensation which is a natural phenomena that occurs with all double glazing . Condensation occurs when water vapour meets with and is cooled on a cold surface. The water vapour then condenses to liquid water and the result is condensation on your windows. Of course with state of the art double glazing because so little heat is escaping the outer pane of glass is likely to remain at a cool temperature and so condensation is possible at certain temperatures and specific conditions and locations. Although there is little that can be done to prevent this happening, it is definitely a good sign that your windows are preventing heat from escaping.
