How to Repair Double Glazing

Double glazed windows are long-lasting and secure but they can wear and tear over time. Double glazing that requires repair is identified by a feeling of draught between the window panes or condensation.

Fogging or condensation between the panes typically indicates that the seal binding the glass panes has been broken. Resealing is a solution to this.

Seals

Seals are an essential component of double glazing, as they boost the energy efficiency and insulation of windows. They are placed between the glass panes of uPVC frames and create an airtight barrier that helps to keep out wind and rain drafts, condensation and drafts which can cause damp on windows and wall sills. Additionally, the window seals help to keep warm air in and cold out, which significantly lowers heating bills.

It is not unusual for window seals to suffer from defects. This is typically due to the weathering process and exposure to harsh elements such as high winds rain, ice, and snow. However, it can be due to an improper installation or the use of chemicals like paint strippers that harm the rubber.

If the window seals fail, moisture and humidity could seep through the glass panes and cause fogging or misting. It could affect the insulation properties of double glazing because it won't have the gas inert between the panes, which helps to keep heat in.
