Sorry - this has been adressed before in this group and I've tried the suggestions that I remember.
My neighbour has 2 misted units; the leaks are due to physical damage to the seals. A local firm has quoted £160 + VAT to replace them or £50 + VAT just to supply them. The units are about 20 years old and about 20mm thick and 350x1020mm. The glazing strip is on the outside (yes, I know...). I've had a goodly struggle and haven't managed to remove anything; this is complicated by the fact that I'm 'experimenting' on mine (identical) so don't want to use too much force. Could some one please tell me how to get the lobody things out before I induce a crackfuckit!
Thanks.
