Acoustic slabs are dense, fibrous insulation materials, typically made from mineral or stone wool, designed to absorb sound waves and improve the acoustic performance of buildings. They are used in walls, floors, and ceilings to reduce airborne sound transmission, enhance soundproofing, and control echoes by trapping and converting sound energy into heat. Acoustic slabs also provide thermal insulation and are non-combustible, making them a versatile and safe choice for both residential and commercial construction.
