Most modern insulated windows and doors contain an insulated glass unit (IGU) which provides insulation from external weather factors. This glass unit is sealed with a special adhesive material that can become broken over time. Once the seal is broken, moisture from the air can enter between the glass panels andcondense upon contact with a cool surface. This creates a foggy appearance and over time can become very noticeable.
What are the implications of condensation in a window?
The glass unit fitted inside all windows and doors is filled with Argon gas. This gas helps to provide insulating properties to the window and improve your homes ability to store heat and keep out cold. When moisture enters this area between the double or triple glazing, the gas is no longer in a vacuum and is able to escape. While the gas is not harmful to health, the window looses much of its' insulating properties when the gas escapes. This excess moisture can lead to damp and mould forming around the window, especially in colder environments.
How to get rid of condensation in windows?
There are a few ways to treat condensation in windows that have broken seals.
Option 1 - Use a spray
A number of sprays available. These sprays offer a short term fix, no longer than a few weeks - as the moisture is still able to re-enter through the broken seals and cause more damage.
Option 2 - Install new uPVC windows
This may not be the most efficient and cost effective way to replace windows with condensation as the window frame is generally very difficult to damage and in most cases has no faults at all.
Option 3 - Replace the glass pane (Insulated glass unit IGU)
With a specialist fitter, this is the most cost effective and efficient way to replace double glazing that has issues with condensation. With most homes windows and doors costing five times cheaper than a new window all together.
