Condensation Condensation is a problem that many double glazing owners will face at some point during their windows' life span.

Hardware Damaged A double-glazed window is comprised of two glass panes, separated by spacer bars, and a gap filled with an insulating gas. It is encased in a frame made of aluminum, uPVC, or wood.
