from single glazing to double glazing
We have a house with wood windows which are single glazing. We thought about getting the windows replaced with double glazing but my husband now thinks what is really needed is to get double glazing put into the existing frames. Has anyone any experience of this and do you know any company or individual who could provide this service? The frames seem wide enough and my husband thinks its a matter of creating a second channel in the frame and fitting in a second pane of glass in that channel.
