Currently we are looking to improve our double glazing windows' energy efficiency. The current double glazing windows look a bit old, we don't know how old exactly they are, but guess they are around 12 years. The glass is 20mm thick and a few of them got Condensation inside. Some of the frame got draughts as well.
Should we just replace the glass unit or replace the whole windows and doors? How much is the price difference?
