Cause of Misted Double Glazed Units – Window SOS

Why Does Double Glazing Get Condensation On The Inside?

The Cause of Misted Double Glazed Units

Did you know?

Usually when one window becomes blown, it's a sign that more misted windows are on their way.

Misted windows can occur for the following reasons:

1. When the installer didn't seal the panes to the required standard and the seal breaks prematurely.

This means that your house isn't properly insulated

2. General wear and tear due to expanding and contacting in changing temperatures

90% of misted double glazing units are facing the South East / South West because of the sunrise

3. Oil based cleaning products and harsh chemicals

These can build up around the surrounding areas, causing the seal to weaken over time and cause gaps

But not everyone knows which way their windows face - let alone how many years old windows are.
Contact the glass and glazing experts if you've spotted a misted window in your house, and we'll have it professionally replaced to avoid the chance of it happening again any time soon.

Our replacement glass is FENSA regulated, which means that the required standard for home insulation has been met for UK building regulations.
