Seals
The seals that are used in double glazing are an essential component of the overall insulation and energy efficiency of the windows. They are located between the glass panes of uPVC frames and provide an airtight seal that helps to keep out rain and wind, drafts and condensation which can cause damp on the walls and window sills. Additionally, window seals help to keep warm air inside and cold air out which can significantly reduce heating costs.

However, it could also be the result of an improper installation or the use of chemicals, such as paint strippers that harm the rubber.
