Does Secondary Glazing Prevent Condensation?

Secondary glazing can significantly reduce condensation on your windows. By adding a layer of secondary glazing behind the existing windows, you create an insulating barrier that helps keep warm air inside and prevents it from meeting the colder outer glass, thereby reducing condensation.
