Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. [ 1 ] Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation ), filtration , soundproofing , and hydroponic growth medium.
Wood wool boards and wood-wool layers in composite boards are generally manufactured using coniferous wood species, mainly spruce and pine. The wood logs are processed to make wood fibres of various widths, generally between 1mm and 3mm. After drying the wood, it is planed into long fibres in a wood wool machine.
