When building in high density areas, building multi-family dwellings, or custom homes that have home theatres, the following are suitable sound isolation products. Sound control is also one of the characteristics that many homeowners are looking at as a good construction practice. Knowing and utilizing these options will be to your benefit.
GreenGlue Noiseproofing Compound
Green Glue Noiseproofing Compound is a viscoelastic compound that can be quickly and easily applied between two sheets of drywall, plywood or any commonly used building materials in new construction and remodeling, effectively eliminating up to 90 percent of noise transfer from one room to another.
Independently lab tested and time-proven in millions of square feet of residential and commercial structures, 440 SoundBarrier is a special-density, structural board made from 100 percent environmental Homasote cellulose fiber, a homogeneous composition manufactured with uniformly distributed protection against termites, rot and fungi and resistance to moisture. It also insulates, with twice the R-value of wood.
Quiet Rock (Quiet Solutions)
Award winning, UL classified, patented QuietRock products revolutionized the building of high STC walls when introduced in 2003. The top selling soundproof drywall in North America (with 1 million panels installed) continues to save builders money and exceed expectations in ease of use, reliability and proven results in over 35,000 projects. QuietRock replaces older techniques such as resilient channels, clips, sound board and vinyl and offer lower cost solutions than other methods with higher STC performance.
