FIBRANgeo B-570 | Stone wool for masonry, roofing and dry construction
Stone wool insulationDescription
FIBRANgeo B-570 semi-rigid stone wool board is a natural, inorganic, fibrous thermal insulation material made from mineral wool, in accordance with EN 13162. It combines superior thermal insulation (λD = 0.033 W/mK), fire class A1 and excellent sound absorption (αw = 1.00 · NRC = 1.00), with increased rigidity and high airflow resistance (AFr ≥ 30) — ideal for ventilated façades.
ARGYNET LAB: The B-570 is the semi-rigid board in the range: lowest D (0,033) and increased rigidity/airflow resistance (AFr ≥ 30), making it suitable for ventilated façades (marble, decorative bricks, tiles, metal panels), as well as for dry construction and roofing. At ARGYNET, we select B-040, B-050 or B-570 and the appropriate coating for each application, with system-level documentation.
