Stable and rigid stone wool slabs impregnated with special water repellent oils; sizes 1000 x 600 mm, thicknesses 20-160 mm.


FASROCK are used for thermal and acoustic insulation of facades in contact facade thermal insulation systems. The slabs are attached to the external side of the facade with a screw with a disk. Over them and their glass fibre mesh reinforcement, a correctional ground coat of special solution is applied. The ready made surface is processed with facade paint or a decoration plaster.
