The exterior wooden beading on our double doors around the DG units is
in need of replacement. There are 8 DG panes in total and I'd need 16m
I have some PVC beading from another job. Would that be ok on a wooden
door, stuck in place with No! More nails! or similar?
I've just had the same problem - but with a custom made wood window with
DG units. Water rather obviously got under the wood beading, and caused
rot, over time. Was most noticeable at the bottom of the panes where water
would tend to collect. The top beads and the tops of the side ones were
fine. But non of the windows leaked into the house.
I did wonder about PVC beading - but found nothing made for the job. I did
find a composite beading made for sash windows which is said to be more
rot resistant - and the same to work as wood. I'm not sure exactly what
it's made of being self coloured all through - white. But breaks rather
like wood if bent too far.
I did wonder if differential expansion etc would make pure PVC a bad
I've use a non setting butyl putty under the beads as well as between them
and the window, hoping this will keep water out.
