Sound transmission is an important concern for occupants in mid-rise residential buildings. Elevator shafts can produce a significant amount of noise and should be acoustically isolated. The material properties of ROCKWOOL ROCKBOARD® and SAFE'n'SOUND® insulation support high acoustic performance: the multi-dimensional orientation and density of stone wool fibers reduces sound transmission across a wide range of frequencies, making it an ideal solution for this application.

Elevators and associated components can lead to electrical fire risk within the building. In the event of a fire, stone wool insulation can add an additional layer of fire resistance around the elevator shaft as it is non-combustible and does not promote the spread of smoke and fire.
