With occupants living in relatively close proximity, sound isolation is critical to occupant comfort in mid-rise wood-framed buildings. ROCKWOOL stone wool insulation is spun out of multi-directional stone fibers that effectively absorb low- frequency sound. Stone wool is also denser than many other insulation materials; together, these properties reduce airborne and impact-related sound transmission. Sound control is particularly important near noise point sources such as mechanical rooms and parking garages; however proper application of stone wool products can effectively isolate these areas.
