The rock wool core version of the membrane-faced roof panel combines the PVC membrane on its outer face with an A2-s1-d0 fire class. The rib height is 37 mm and the profile has five ribs.
This panel suits buildings where the regulations require class A2 and the roof is low-pitched: the membrane handles the water side, the mineral core the fire side. Thermal conductivity is 0.045 W/mK, so the insulation target is met through thickness; thickness goes up to 200 mm.
A rock wool core loses its insulation value when it gets wet; protecting it from rain during stacking and sealing the joints watertight are twice as important with this product. Details are in the Library section.
