Sound Control

GreenFiber Cocoon Insulation is extremely effective in controlling sound transmission. This is especially true for airborne sound that is generated by traffic noise, airplanes, radios, televisions and conversation. This type of sound transmission can be significantly reduced by installation of GreenFiber Cocoon Insulation in ceilings, walls and between floors. In open attics, GreenFiber Cocoon Insulation easily molds around irregular construction and stays in place, fitting snugly against framing members and even moderate slopes.

GreenFiber’s insulation fibers have a natural tendency to trap air. It is also dense. The combination of these two characteristics provides effective noise reduction in walls and between floors.

Walls in new or existing construction that are insulated with GreenFiber Cocoon Insulation are able to suppress sound transmission much better than traditional batt materials. By completely filling spaces where sound can travel, GreenFiber Cocoon Insulation reduces the sound that can pass through gaps in batt-insulated walls.

Special effort should be taken during construction to make all walls, ceilings and floors airtight in order to eliminate any potential leaks for sound transmission. The staggering of outlets and plumbing is also recommended.
