The glazing part of the conservatory has come to the end of its life, but the base and the dwarf walls are fine. We are therefore having the conservatory roof and windows only replaced.
The company has taken down the roof and windows which has revealed - as expected - the walls cavities are not insulated. The cavity is pretty narrow (approx 60mm between the bricks) so the total volume of the cavity for all walls is about 40cuft.
Although I have some 50mm celotex, I can't use that because of the ties which stop me sliding the celtex down. So I was thinking of using EPS beads which I could pour in from the top and gently rod to ensure no voids.
I know these wont be glued like a professional blower, but as they are mainly dwarf wallsthey are unlikely to be drilled or cut into so no real risk of a snow storm for later changes
Any comments - like dont do it, or seems like the best solution
