Insulation & Noise Reduction


While homeowners usually think of insulation as an energy-saving measure, it can also reduce noise. Insulation materials can block the transmission of sound from room to room.


  • Builders Websource defines insulation as any material that prevents the transfer of energy between two surfaces. Insulation in a home prevents heat from moving between walls or floors.

Noise reduction

  • Insulation provides noise reduction as well as energy efficiency. A home with proper insulation will transfer less noise between rooms, helping to mute the sounds of household appliances, phones and other daily distractions.

Forms of Insulation

  • Acoustic insulation often comes in rigid panels of varying widths, depths and sizes, while 24-inch sheets called "blankets" can cover larger areas. The Acoustic Insulation Materials website states that most attics require insulation at least 6 inches thick.


  • Insulation materials commonly include foams, such as polystyrene or polyurethane. A type of polyurethane called Rockwool consists of mineral fibers stitched into panels. Even ordinary fiberglass insulation can block noise.


  • The Acoustic Insulation Materials website warns that some insulation materials can cause skin, eye or lung irritation when handled without protective gear.
