I have a double glazed window in my bathroom that has 2 non-opening

without going through the hassle of changing the whole window frame?

With regards to the other posts here - you can no longer diy D/G. You have
to inform the BCO at your local council and get his/her permission before
starting - otherwise you fall foul when you come to sell the property.
Whether or not you can *THEN* diy the D/G installation I'm not sure, but I'm
sure someone else will be along shortly...
