Insulation above slab on ground – CF005b


Insulation above slab on ground - CF005b

Dow Styrofoam RTM-X

Confirm with a structural engineer for the required compressive strength required. Ensure slab is clean and free of loose material.

Lay insulation boards in brick pattern with edges pushed together firmly, cut neatly around penetrations.
