We are midway through renovating a 1930s house and currently have booking for bead type cavity wall insulation on external walls in the house. The problem is that later on we are planning to replace the external doors and door frames which have gone rotten (including a large front door). Generally speaking, is it likely that once door frames are out, the cavity is exposed and if so is it likely that we'll get insulation material everywhere and cold spot above the door? Cavity is 50mm.

Modern day EPS bead will be bonded with a very weak glue so they will not fall out unless you poke or scrape at it.

to give you an idea, i recently cut new openings for a doorway and a window in a house that had the cavity filled last year. Once i cut one leaf I literally just sawed the stuff very gently around the perimeter of the opening and it will came out in one big slab.

Mind you the slab will barely stay together once its out but the stuff within the wall will not go anywhere unless you poke/ rake at it
 
My 1930's house has a similar poly bead cavity insulation. It's not bonded together with anything, but it does seem to have compressed together over the years to the extent that it behaves reasonably well as long as you don't agitate it.

If you leave it for any length of time though, you do start to discover while balls getting everywhere in the house!
