How to soundproof your interior walls, floors and ceilings

ROCKWOOL Safe'n'Sound® is a stone wool insulation for use in interior partitions of residential wood and steel stud construction where superior fire resistance and acoustical performance are required.

Withstanding temperatures up to 2150°F (1177°C), Safe'n'Sound® is non-combustible and will not produce toxic smoke or promote flame spreading, even when directly exposed to fire. This adds valuable extra time for people to reach safety and for fire services personnel to arrive.

Safe'n'Sound® has excellent acoustical dampening properties and provides an easy friction fit into walls, ceiling and floor applications. It is GREENGUARD Gold Certified and contributes to a healthier indoor environment.

I am a voice performer for documentaries, corporate presentations, and commercials. A major requirement of voice recording is to have a recording environment that is as silent as possible. My voice recording booth, weighing approximately 1, 000 pounds, is insulated with ROCKWOOL Safe'n'Sound® in all four walls, the ceiling, and the floor. Other than one other voice booth—the very expensive, anechoic chamber at the US Military Academy at West Point—it is the deadest space in which I've ever recorded. The installation of the Safe'n'Sound® was just as simple and easy as shown in this video. Thanks for an extraordinary product.

Why is it thinner than a 2x4, and have less material, but yet more expensive than standard rockwool insulation?
