The windows in both children's rooms need replacing. They are horrible aluminium early double glazing.
Our house is an Edwardian semi and the shape of the windows looks like they were originally sash. We are gradually doing the house up and would hope to reinstate sash windows especially at the front of the house.
Are sash windows suitable for children's rooms? They seem to open really deeply (?). And any idea how much two windows might cost (they are just straightforward rectangles, not boxed or anything)?
TIA
