We currently have a single glazed secondary panel screwed to the inner frame of a wooden sash window.
With an increase in traffic noise it's no longer up to the job and I'm considering replacing with a double glazed panel but these don't seem to be readily available? We can get sliding units that are 70mm deep or regular replacement units ready to go into a frame, but have not yet found a supplier of a simple screw on panel similar to the single glazed version.
Do they exist?
