PAROC COS 5 is a thermal insulation slab (lambda 0.035W/mK) used in concrete sandwich elements. The insulation slab is attached to the element during factory casting.
The compressive stress of the slab is 5 kPa which means that it can withstand a 500 kg/m2 load during casting.
Stone wool's porous structure and excellent water vapor permeability allow the building moisture of the element to dry through the insulation layer to the outside as well. Faster drying of the inner shell speeds up the start of finishing work on the inner surfaces.
