The following are the most common causes of misty demist double glazing-glazing:

Problems with ventilation

Double-glazed windows are made up of two glass panes that are separated by the spacer. The spacer acts as a thermally effective barrier and is filled with gas or air. When this seal fails, moisture gets in between the window panes and causes misting. Misted double glazing is not just unsightly, it also affects the efficiency of your home's energy insulation.

There are a myriad of reasons a sealed device may fail, but general wear and tear is a significant reason. Over time, the seals can become weaker due to temperature changes, which causes them to expand and contract. As the seals deteriorate they could be destroyed completely and allow water to enter the window.

Poor installation is another reason why a seal is not working. This can cause issues such as inadequate drainage, gaps in the frame, and inadequate spacing blocks for the window units. This may also occur when harsh cleaning chemicals are employed or curtains are not properly fitted.

Double glazed windows can be affected by humidity. Moisture in the air can condense on any cold surface, and this is the case in particular of glass windows. The moisture will then run into the interior of the window and form a fog or condensation.

This is an indication that the double-glazing has failed and requires replacement or repair. Moisture between the windows can cause loss of heat, which could increase your energy bills and cause discomfort in the home. It can also impact the soundproofing in your home which allows outside noises like traffic and machinery to easily get through.

There are ways to fix the problem and prevent it from happening again in the future. One alternative is to have your double glazed windows cleaned by a professional company.
