The reason being is that the seal in your thermal glass has deteriorated over time of which is completely normal after 10-15 years and the argon gas has leaked away allowing moisture in glass. Not only is it unappealing to see condensation in your window but the most important part is that you're losing energy. This means you're home is working harder to warm up or cool a certain room. Here at Cana Glass we offer foggy glass repair by replacing your thermal glass with brand new energy efficient argon filled thermal glass.
A good life span for a thermal glass is between 10-15 years. Every home owner will eventually experience this, don't think you're the unlucky one If you're tired of your view being ruined by condensation, moisture and your room being too hot or too cold contact us and we'll send a certified glazier to explain everything and give a free quote.
*** Before changing your windows please give us a call as you could save a fortune by replacing just the thermal glass itself and getting better energy efficiency than changing your whole entire windows.***
- If you can't successfully wipe it perfectly clean and there is moisture/fogginess in between the glass panel then unfortunately the unit is dead. (a dead glass unit means the seal has been compromised and is no longer energy efficient).
