Manns or something similar for the varnish. Anything properly waterproof would do. I can’t remember what glue I used tbh, probably something in a cartridge.
The rebate fits over the frame of Velfac windows, timber goes right up to the glass. This gives a good idea, though all the other windows had a lot more noggins or whatever you’d call those bits of wood.

I glued all my window liners - four sides ~250x19 with a huge rebate. No movement as far as I can see. I used a fully waterproof PU varnish on the under / glue side.
PU foam is gross. Avoid.
