Nothing lasts forever, and that includes double glazing. You’ll notice that while Stonehenge is still standing after several thousand years, its windows are long gone. One of the first signs that your double glazing is failing is condensation that you can’t wipe away because it’s trapped between the panes.
Pane in the glass
When double glazed units are made, they have a seal around the edge. This establishes the gap between the panes and holds in the gas that provides a thermal barrier between the inner and outer glass. Over time, these seals can deteriorate for several possible reasons.
If the frame is not properly drained, the seals could be sitting in water, which will eventually seep in. Frames that are regularly damp can also be subject to the growth of mould, which can contribute to the frame seals breaking down.
Big changes in temperature can also have an effect by causing the seals to expand and contract to the point where they eventually fail. In Ireland, we are no strangers to wet weather and high humidity, and this can also contribute to the failure of seals over time.
Incorrectly cleaning windows using strong chemicals can also be a contributor to the failure of seals. You should avoid using products that contain bleach and stick to milder detergents, or you can use the traditional method of vinegar and water.
What can you do?
If the seals on your glazing have failed, what can you do about it? If you have relatively recent windows Dublin based suppliers like https://www.keanewindows.ie/windows-dublin/ always offer a guarantee, so the first thing to do is to check to see if they are still under warranty. If they are, you can get the supplier to fix the problem. Early failure of seals is usually a sign of a defect in the product.
On older windows, you may need to replace the window entirely. If you go down this route, it’s important to make certain that the frames are in good condition. It’s pointless to put new sealed units into an old, leaky frame. Although it may cost more to replace the whole window, frames and all, this will ensure that your new glazing has a longer life and shouldn’t need attention for many years to come.
