Misty Double Glazing Repair

Misty double glazing happens when the airtight seal that is used to hold the two panes of glass in a double glazed window fails. This allows moisture to get into the window and decreases its insulation properties.

It can be cheaper to repair your windows professionally than to replace the entire window. This can also help to prevent further damage and condensation issues.

Seals

A window seal, also called a uPVC window seal, is the essential element that helps keep your double glazing clear of mist and in good condition.

Windows are an essential feature of any home, providing light, ventilation and a connection to the outdoors. However, they can also be a major source of energy loss.

Regular maintenance and high-quality installation can help prevent this.

Most people assume that a misty double-glazing window means that the frame has failed, however this isn't the scenario. It's usually the seal that has failed, allowing the gas that insulates between the panes to escape. The most effective way to correct this is replacing the sealed unit, instead of replacing the entire window. This is a less expensive option that will save you money over time. It's also an excellent opportunity to upgrade to energy-efficient glass A-rated, which can further increase your savings.

Double glazed units that fail are also referred to as steamed up windows and they occur when the hot melt sealant that creates an enveloping seal between the two panes of glass fails.

This can be seen as streaks of steam on the interior of the double-glazed window. It's more noticeable in warmer weather.

In the beginning, the issue might appear to be solved by adding warm air to the window. This is a temporary solution but it could be beneficial. Avoid extreme temperature changes as they can lead to condensation. Make sure that the temperature remains as stable as possible.
