Similarly to other crucial aspects of a buildings structure, fire protection (to reduce the spread of fire) and insulation (to reduce heat loss) are essential, this does not change with regards to concrete soffits.
The Rockwool Soffit Slab is a mineral wool fire resistant insulation for concrete soffits, not only does the soffit slab offer thermal and fir protection benefits it also provides important acoustic benefits.
The Rockwool Soffit slab achieves a thermal conductivity of 0.034/mK as well as offering up to 4 hours of fire resistance. The Soffit slab comes in thicknesses from 130 to 160mm.
