Sound Insulation for the Home

ROXUL SAFE‘n’SOUND® is a stone wool insulation product for use in interior wall partitions of residential wood and steel stud construction where superior fire resistance and acoustical performance are required. This non-combustible, lightweight product has excellent acoustical dampening properties and is dimensionally stable which makes it ideal for friction fit into walls, ceiling and floor applications. The product is chemically inert; therefore it will not promote corrosion.

Sound control and fire safety from one batt Insulation

Roxul_soundinsultationROXUL SAFE’n’SOUND® is a batt insulation designed specifically for interior wall and floor/ceiling applications. This stone wool insulation is made from natural stone and recycled content. It’s a green product that provides superior sound absorbency and fire protection for overall comfort and safety. Because SAFE’n’SOUND® is designed for interior applications, it has not been engineered as a thermal insulation but as a fire barrier and for soundproofing. Stone wool in general has excellent fire ratings, does not burn and can add valuable time for evacuation in the event that a fire occurs. Its higher density properties also make it an ideal solution for minimizing sound travelling between rooms.

Home life has changed, and sound dampening is more important than ever

We live in a louder world today. Modern life is noisier, due in part, to increased traffic congestion and the Roxul_soundinsultation-installationintrusion of unwanted sounds seeping into our home environment. Think high-tech entertainment rooms, pinging computers, blaring stereos, ringing phones, washer/dryer rumblings. And let’s not forget about your son’s band practice in the garage. This cacophony of noise contributes to a form of sonic pollution, a growing problem that can rattle nerves and affect our sleeping habits and quality of life. Most of us cherish a quiet environment to think, work and rest, an environment ROXUL® knows very well, thanks to ceilings and walls that acoustically perform better when fitted with ROXUL SAFE’n’SOUND® insulation. All sounds come from energy made by vibrations travelling through air, water or solids. When a sound source (e.g. crying baby) vibrates its vocal chords, it causes air particles to radiate out in all directions. These radiating air particles continue to exert force on other air particles, causing more vibrations, which in turn, collide with more air particles.

Impact noise versus airborne noise

Properly insulating your walls and ceilings with ROXUL SAFE’n’SOUND® will make your home a more peaceful and quiet haven because it will help ensure that sounds won’t travel from the outside, or to and from other rooms. Before soundproofing a ceiling or wall, consider the kind of noise problem you’re trying to solve. Is the problem impact noise or airborne noise, or both?

Impact noise refers to the sound made when one object strikes another object on a hard surface. In the home, impact noise can come from the sound of footsteps, the slamming of doors, furniture dragging or items dropped onto the tile or hardwood floor above. These low frequency sounds can be a major source of annoyance. Adding extra sound dampening mass such as carpeting can alleviate the problem, or resilient channels can be installed in order to de-couple the drywall from the studs. De-coupling methods such as this can help to diminish the transfer of impact noises from one room to another.

Airborne noise, on the other hand, refers to the sound travelling from outside (aircraft, cars, lawnmowers,) or inside (voices, music and appliances) from the above floor, or from adjacent rooms. In this scenario, adding sound deadening elements such as extra mass, (e.g. ROXUL SAFE’n’SOUND® insulation and air space in the wall or ceiling assembly) can reduce the transmission of airborne noise.

ROXUL SAFE’n’SOUND® soundproofing insulation is perfect for applications such as:

  • Bedrooms
  • Home Offices and Libraries
  • Bathrooms
  • Basements
  • Home Theatres and Music Studios
  • Furnace and Laundry Rooms

ROXUL insulation is available at Lowe’s, Home Depot and many lumberyards throughout the U.S. If not available on-shelf, product can be special-ordered at the contractor desk. When working with a contractor, homeowners can specify ROXUL insulations.

ROXUL, the North American subsidiary of Rockwool International, is the world’s leading producer of stone wool insulation. For over 25 years, ROXUL has been supplying stone wool insulation for residential and commercial applications throughout North America with production facilities now located in Mississippi in the USA and in Ontario and British Columbia in Canada.
