Just had a wooden casement cottage style window installed, 20/24mm
double glazed units were put in on site by builder. It doesn't appear
that he has used putty - is this normal? There appears to be some glue
or sealant between the beading on the outside and the glass but that's
about it. It does give the window a very neat appearance, particularly
on the inside where there is nothing between wooden frame and glass,
well nothing visible.
