NRP7 Rock Wool is the rock wool cored version of the seven-rib roof profile. The rib height is 24 mm and the fire class is A2-s1-d0.
The point where the seven-rib profile meets the rock wool core is clear: industrial roofs where a wide span and A2 class are required together. Since the thermal conductivity is 0.045 W/mK, the insulation target is met through thickness; thickness goes up to 200 mm.
The core density is in the 90-130 kg/m³ band and the weight of the shell is carried by the load-bearing structure; read the weight from the panel weight calculation. Load tables are in the Library section.
