Hi
I have a utility room with a concrete floor & no insulation in it. The floor level needs raising by about 30-35mm to bring it level with the adjoining kitchen floor.
I was going to lay a dpm then a 30-35mm concrete slab to bring it to level, but was thinking instead of including some insulation into it.
Can I lay 25mm celotex boards on existing floor, then screed/floor level compound over it? Will I have issues with compression and have too thin a layer (5-10mm) of screed/self level compound?
25mm celotex
Fibre reinforced self leveller
They also do a 12mm board, but wanted 25mm to add as much insulation as I can.
Cheers & happy new year.
