just watched a few bits of this. I don't understand why he would put the rebate inside. I see it makes a a fake putty bead. and it allows bead glazing but what am I missing. he does say to drain the rebate just in case but I can't see that working for years.
I like him but I struggle to follow him to be honest but it must make sense.

If you use a modern dry-glazing system, it surely makes some sense to internally bead. I made the sash windows for our house (in Accoya) with 24mm DGU basically copying the drawings from one of the big commercial manufacturers of wooden sash windows who put the CAD drawings of their ranges online - all internally beaded and dry-glazed.

I used EPDM seals and Reddiseals dry glazing clips. I did drill a couple of drain holes into the rebates just in case, but TBH it looks like this was unnecessary.
