The rock wool core version of the open-screw wall panel combines visible screw fixing with the A2-s1-d0 fire class. The profile is micro-ribbed.
It is used on industrial façades where regulations require class A2, in production areas with a high fire load and on façades close to a neighbouring plot. Thermal conductivity is 0.045 W/mK; the insulation target is met through thickness, and thickness goes up to 200 mm.
A rock wool core loses its insulation value when it gets wet; the panel edges must be sealed tightly and the panels must be protected from precipitation during stacking. Details are in the Library section.
