My daughter has asked me to glaze an external hardwood door she is
having made for her. It's a small pane configuration rather than
one large sheet of glass. I understand that the joiner will be
supplying the beads and the glass will come from the local glazier.

What do I bed the glass into ? I would have thought that something
flexible should be used to account for the slight flexing of the
door. Putty I would have thought would in due course set hard and
crack.

Thanks in advance

Putty is about the best you can use, or a non setting glazing
compound if it's not going to be overpainted:

Don't be tempted to use silicone - it holds the water in the recess
and eventaully rots the timber...cue the uproar.

Uproar :-! (was tempted to use caps but thankfully refrained)

As a contrast, I've seen too many of such installations fail with
water ****ing in past the panes (or through the joints) so would
recommend a cautious back fill or total fill with silicone. Truly,
silicone is an evil substance for getting where it is not intended
but sealing of multi-paned windows & doors is (IMO) one of the
acceptable uses.

If done properly and with great care, it is a good glazing sealant, the
trouble is, it's w-a-y too easy to make a balls up with it - I've seen
'professionals' do it wrong....they all try to do the same thing - avoid
having it ooze out upwards where the glass meets the rebate or the beadings,
presumably because they don't want to cut it/clean it off the glass
afterwards, end result is that it's left below the timber line and a gap is
present, usually internally *and* externally which holds the rainwater *and*
condensation!!


If the door is intended to be semi-secure I'd follow dom's advice of
taping the glass in (6.4mm laminated) followed by a back fill of
silicone and fitting of glazing beads before it sets.

Butyl rubber glazing compound is expensive but it works, it never completely
sets or cracks, and is easy to cut, remove/clean up etc afterwards.....it
has all the workability of putty but none of the disadvantages.
