Single to Double Glazed

Most wooden box sash windows pre-date the invention and introduction of sealed unit double glazing and are of single pane construction. Whilst they look great they are not so good at retaining heat and cutting energy usage but this need no longer be the case.

AP Joinery will gladly conduct a free inspection of your sash windows to determine whether or not your windows are able to be converted and we will then work out a fixed price quotation without obligation.
