Misted Double Glazing
Misted Glass is the result of excess moisture trapped in the cavity
between panes of glass in a double or triple glazed unit.
This is caused where there is a breach in the hermetic seal (airtight
seal) around the edge of the sealed unit allowing moist air to enter the
cavity of the unit over a period of days, weeks or months.
When the temperature rises the moist air trapped within the double glazed window unit condenses and over a period of time gives a white cloudy effect which to the eye is irritating and unsightly.
Over 90% of failed double glazing sealed units are south-east to south-west facing due to the fact that the sun rises in the east and sets in the west providing the greatest change in daily temperature which in turn creates the most movement in the window and door frame through expansion and contraction.
With decades of experience working with windows, our professional opinion for repairing a misted glass units is to replace the glass. As all misted units are subject to a fault in the unit itself and replacing the glass will avoid any more costly issues later on down the line as well as ensuring the new low emission glass is completely sealed with warm edge spacer bar technology and filled with argon gas to ensure your windows are energy efficient. This service is available for UPVC or aluminium units and comes with a comforting 5 year warranty.
