Posted By: goodevansI am assuming that insulation systems that sit below the B&B are expensive compared to above the B&B - in addition finding them with 200mm or more of platinum eps below is even more difficult.
Posted By: barneyIf the B&B combats heave then loose fill the void with EPS beads and have the B&B mass inside the thermal envelope
Posted By: barneyI was simply suggesting that it's credible the unventilated void can be filled with loose insulation (to combat heave) and retain the B&B within the thermal envelope - acting , as you suggest like cellcore would in a "heave" situation
Posted By: barneyI'm working on a project at the moment where it's failed spectacularly under a ground floor slab onto beams and piles
There is evidence that it's already collapsed whilst the floor slab was being poured (although the slab is about 750mm thick for various reasons so an awful lot of weight imposed on the cellcore)

good key, not to heavy
some where between a medium dense and an aerated.
also these in order of preference are worth a look ,
Fenlite (some recycled aggregates)
Hemelite
