To acheive this result has not been easy. Georgian bar Sash windows are notorioulsy difficult to double glaze sympathetically. Most conservation officers are well aware of this and often insist that windows remain single glazed. The main problem is the width of the glazing bar, this can be as narrow as 16mm but more typically it is in the 19-28mm range. It's all the Georgian's needed - as there was no spacer bar to conceal, then a circa 6mm glazing rebate would suffice.
Acheiving the look of single glazing with double glazed sashes is not easy. It is essential to match all the dimensions of the origional sash exactly, including the glazing bar and as can be seen on the final picture, where our double glazed Georgian sashes are adjacent to a property with the origional single glazed windows, it is exceptionally hard to tell which one has been double glazed.
