Gap around the glass?

[CarlP]

Should I have a small gap around the glass edge in a double glazed unit?

I have just removed the beading from a window and all but one side meet the frame - this window has actually misted hence the reason for trying to replace it.

Also any Idea of where I could get fresh beading from?

CarlP,
There should be a gap all round the DGU and setting blocks should be fitted at strategic positions aroung the frame.
A local glazing firm should be able to supply you replacement beading but take a sample so you get the same section.

Thanks for the help

what a result
window 15 (glass supplier) blocks 6 (ebay) no beading required
total 21 to replace one window
