Rock Wool Board is made from basalt, an inorganic raw material. It is produced through heating basalt at 1350˚C - 1400˚C and transforming it into fibers, which are bonded together using a thermosetting resin. It is light and easy to install, mainly used for thermal and acoustic insulation where high compressive strength is required such as over-deck, floors, sandwich panels, and dry wall partitions.
Sound absorption:
The open fiber structure ensures the rock wool good characteristics of sound absorption.
