Best sound insulation material for walls.

Rockwool safe n sound is a great alternative to rockboard is a high performance soundproofing insulation material ideal for soundproofing walls and ceilings. The most common kind of batt insulation is made of fiberglass which is durable and fire resistant. It is not flammable and will tolerate temperatures of up to 1000 c. The material can be used on the walls ceiling and corners and are used as panels baffles and bass traps respectively.

It has a unique wedge or pyramid shape which increases its effectivity to absorb sound. Blown in cellulose insulation is made of 75 85 recycle fiber from paper with the remaining 15 25 made of a fire retardant material. It is commonly referred to as studio foam. Sound damping materials are the most effective when they re between two hard surfaces.

It s soft and flexible making it easy to tightly stuff the batts into standard stud wall cavities. It is made from mineral wool meaning that it is far denser than other insulation foams. The more loosely packed the fibers the better their ability to absorb and dampen sound. The two surfaces usually drywall or plywood are then attached to each other.

So when sound reaches one of the layers of drywall it causes the panels to vibrate against the damping compound which then converts the vibrations into heat.
