Underslab Floor Insulation

ROCKWOOL rigid stone wool boards used as a continuous layer of insulation under a concrete slab can provide the thermal efficiency and mechanical properties required as an alternative to rigid foam.

These stone wool products can be installed under poured concrete slabs and above crushed stone, as well as between the slab edge and the foundation wall, to act as a thermal break.
