Hi All,
I'm in the process of constructing the slab foundations prior to pouring the concrete for a kitchen extension.
I'm planning on installing wet underfloor heating and looking for the best way of insulating the slab.
My architect has drawn the slab as such, from kitchen floor down:
Screed, insulating bats,DPM, sand, concrete, harcore, ground.
My builder mate who's helping me insists he's always put slabs in as follows:
Screed, DPM, concrete, insulating bats, sand, hardcore, ground.
Local building reg's officer does'nt mind either way???
I'm of the opinion that with a layer of insulation before the concrete slab the UFH will be more efficient? So better the architect's way ?
Its a battle of wits at the moment.
Cheers
