Sound Deadening
What Is Sound Deadening?
Insulation has many purposes, including improving comfort and energy efficiency. One more important function of insulation is sound deadening, which diminishes noises from passing cars, neighbors, barking dogs, and interior sounds between rooms.
Sound deadening (muffling and diminishing sound waves) is accomplished by installing specialized types of insulation, while sound proofing (completely blocking sound waves) is achieved through the use of additional materials other than insulation.
Many various insulation products can be used in order to deaden sound: fiberglass, open cell spray foam, rockwool, K13, Monoglass, Sonoglass and denim. Each product offers a different Sound Transmission Class.
What Are STC Levels?
STC or Sound Transmission Class is the rating of a product’s efficiency in reducing noise between ceilings, walls, floors, windows and doors. Determine the STC level needed for the room and insulate with the product best suited to reach the effect.
