FIBRANgeo B-001 | Stone wool for masonry, roofing and dry construction
Stone wool insulationDescription
The FIBRANgeo B-001 semi-rigid stone wool board is a natural, inorganic, fibrous thermal insulation material made from mineral wool, in accordance with EN 13162. The stiffest board in the range combines top-class thermal insulation (λD = 0.033 W/mK), fire class A1 and excellent sound absorption (αw = 1.00 · NRC = 1.00), with the highest airflow resistance in the range (AFr ≥ 50) — available from 20 mm for ventilated façades.
ARGYNET LAB framing: The B-001 is the top-of-the-range product in the FIBRANgeo series in terms of rigidity: a λD of 0.033 and the highest air flow resistance (AFr ≥ 50) make it the preferred choice for ventilated façades (marble, decorative bricks, tiles, metal panels), where the insulation is exposed behind the cladding. At ARGYNET, we scale the selection from B-040 → B-050 → B-570 → B-001 as required, with system-level documentation.
