Understanding Double Glazing Fog: Causes, Solutions, and Maintenance

However, one of the typical issues property owners come across with double-glazed windows is fogging between the panes.

Cause

Description

Seal Failure

The most common factor for fogging is a compromised seal, allowing moisture to enter the air area.

Temperature Fluctuation

Modifications in temperature can produce pressure differences that compromise the seal over time.

Incorrect Installation

Incorrect setup can cause stress on the seals, increasing the likelihood of failure.

Age of Windows

Over time, elements such as wear and tear can trigger seals to weaken.

Poor Quality Materials
