Stone wool insulation
FIBRAN B-050 (FIBRANgeo B-050) Stone Wool, 50 mm
Three protections in one board — thermal, acoustic and fire insulation.
FIBRAN B-050 stone wool is a non-combustible mineral wool board for drywall systems, walls and ceilings that insulates against heat and noise while protecting against fire. Made from volcanic rock, it is 100% recyclable. One pack covers 7.2 m² of surface.
Year-round thermal insulation
FIBRAN B-050 stone wool traps dry, still air between its fibres and slows heat transfer between warm and cold surfaces. Rooms stay cooler in summer and warmer in winter, while heating and cooling bills drop. Its low 0.035 W/mK thermal conductivity stays stable for the life of the board.
Acoustic insulation against unwanted noise
The fibrous structure of FIBRAN B-050 absorbs ambient noise and reduces sound carried through walls and ceilings. The board improves room acoustics and suits partition walls in drywall construction. Its high airflow resistance delivers consistent sound absorption.
Non-combustible fire protection
FIBRAN B-050 stone wool is a fire-resistant material that withstands working temperatures up to 750°C. Built into walls and ceilings, it slows the spread of flames and provides fire resistance of up to 120 minutes. That buys valuable reaction time in a home or building fire.
Use in walls, ceilings and roofs
FIBRAN B-050 fits into partition walls with a stone wool core, cavity walls, non-perforated suspended ceilings and between timber floor joists. The 600×1200 mm boards install easily in single or multiple layers. The material is eco-friendly and fully recyclable.
