Any idea what they might have used as a release agent?

Oddly enough, 'silicone spray lubricant'..

Think I'd much rather use a excess of physical barrier (aka cling film)

rather than spray stuff that might be a bit patchy. It wouldn't take much

not to release to have the window siliconed shut and working out where

that was to slice it through with a blade could be a right begger...

I think I'm with you Dave, although there's always a case for empirical evaluation(!) so I'll try to have a
go at some of the suggestions here and see what works best. *Clearly it would be a lot simpler to just
seal things shut, but that might not be too useful for a door, for example (!)

In principle, it could be a useful way to draught proof an irregular gap that's not suitable for a weather
strip, though I suspect it would need a bit of ongoing maintenance. *I was thinking mostly about
temporary measures in some draughty places (I have plenty) pending doing a proper job.

Scrape both mating surfaces.
There is a primer for the side that is to get the silicon but I am not
sure it is needed. (pretty sure it is expensive though.)
Apply non stick washing up liquid grease or whatever.
Run bead of clear silicon down rebate.
Close window.
If you have a choice of closures use the sightly open notch on the
lever.
Next day give the casement a judicial going over.
If it is too fast, inset thin blade along joint.
