WHAT DO I DO IF I SEE CLOUDING OR FOGGING
BETWEEN THE PANES OF GLASS?
Clouding or fogging of an insulating glass unit occurs when there is a break in the inner seal between the glass panes. As a result, condensation forms between the two panes.
Units manufactured after January 1, 2000, have a 20-year seal warranty. If there is a problem with the seal of the glass, obtain the serial number from the roof window or skylight and contact VELUX.
We will be glad to help to determine if the products warranty is still in effect and what actions can be taken to correct the issue with the seal.
