Why Do Double Glazed Windows Mist Up?

Double glazing condensation forms when the airtight seal around the unit breaks down. This seal failure allows moisture to enter the space between the two panes of glass. Because the condensation is trapped inside the sealed unit, it cannot be wiped away from either side.

Common causes of a failed double-glazed unit include:

·       Ageing or deteriorating seals

·       Prolonged weather exposure

·       General wear and tear over time

Yes. In most cases, you do not need a full window replacement. Here at Glasgow Glass and Locks, we can replace the double-glazed unit itself while keeping your existing window frame intact.
