Noise Reduction for a Quieter Home

Owens Corning EcoTouch® insulation offers more than lower energy bills. It is also a great sound dampening material. The glass fibers in fiberglass insulation are excellent at reducing sound transmission through the walls and floors of your home.

Noise Reduction Comparable to Mineral Wool

Did you know?

  • Fiberglass and mineral wool are two of the most commonly used cavity insulations for noise reduction in walls and floors.
  • Both materials are tested for sound dampening performance and both meet or exceed building code requirements depending on the assembly.
  • Sound Transmission Class (STC) is a single number rating used to compare various assemblies for their ability to reduce the amount of sound traveling through the assembly.
  • On average, fiberglass batts have equivalent or better STC acoustical performance than nominal equivalent thickness, and higher density mineral wool insulation.

Competitive Fiberglass & Mineral Wool - Wood Stud Assemblies STC Performance

The tables below show STC ratings of the same wall assemblies with either fiberglass or mineral wool filling the cavity. The information is from a study, "Sound Transmission Through Gypsum Walls: Sound Transmission Results" Internal Report IR-693, performed at the National Research Council of Canada. This study was jointly funded by fiberglass, mineral wool, cellulose and other building material manufacturers.
