I have an extended garage that was converted into a sauna/shower/mudroom by the previous owner.
The problem is the slab is uninsulated :x and the person who remodeled the "garage" attempted to insulate the floor d^_^b by framing the floor 150 mm and then putting fiberglass insulation between the joists, followed by chipboard and a plastic mat. But the floor is still ice cold q(;^
p!
Could it be that the cold is creeping up into the joists that are against the concrete, with a vapor barrier in between?
My Solution: I am considering opening the floor, tearing out the joists and insulation, and then laying in foam insulation, chipboard, and gypsum without joists against the concrete, essentially a floating floor on the insulation.
Am I completely off track or should I go ahead .:S

If the floor is flat, it wouldn't work unless you have a platonmatta at the bottom, so they can circulate and breathe from below, then cellplast on top of that, and then put on the particleboard. It's important to have some type of ventilation; the floor becomes warmer because of it, platonmatta solves it.
Leveling strips otherwise? air gap underneath and the insulation is not against the slab but up against the chipboards
