Black insulating material wallmate xenergy from extruded polystyrene with added carbon, for insulation of double masonry mainly in new constructions. Carbon additives give a reflective feature against radiation. The dimensions of the concrete are 2500 x 600 χ30. The value you see is a square value (m²).
Compression Resistance: CS (10/Y) 100
Water absorption: WL (T) 0.7
Water vapor permeability resistance m (air m = 1): 100 – 250
