We have an old victorain house and the windows are draughty single glazed ones. Some of them are also shaped at the top. We live in a conservation area and I'm not sure we would be allowed to replace them, even if we could afford to. We want to make the windows less draughty and wondered if we could get some secondary glazing fitted. Does anyone know the answers to the following:
Could not-very-good DIYers fit sec glazing themselves? Would we have to get the rounded shaped windows made specially to fit, and who might do this?
