I still rended my outside walls then fix 27 mm insulated plasterboard to them.
Should b/c insist that the insulation in the plastering needs to be increased, is there a way of doing this with more traditional plastering (hardwall, bonding etc) ?
Hardwall I think has the highest insulate value out of the float coats.
E.g. you could easily imagine the situation where the client was after a float & set for a more solid result (as jesteh above).
But if b/c requested the insulation is increased, is the only option then on the plastering to use insulation-backed p/board with skim on top?
that is something that I really can't answer but it does look like that may well be what's coming for some like myself,
my walls are solid 9 & 18 inch, jesteh has a cavity wall so with that filled and a hardwall float coat b/c should be happy.
