Q. When cracked glass is replaced will the sash window still be weighted correctly?
A. No, modern glass is 4 mm thick and the original was only 2mm. The windows will need to have additional weights added to ensure a perfect balance.

One of the above is Double Glazed - Which one? The window on the right is a 14mm slim line double glazed unit with a 27mm astrical. Split down the middle into a
2 over 2 with a 'through' astrigal making four individual double glazed units.
