What is soundproof sheetrock?
Soundproof sheetrock is regular sheetrock (also known as drywall, gypsum board, or plasterboard) that has been factory dampened, or treated to block the travel of sound. Sheetrock is a common building material used in the construction of walls, ceilings, and floors. It is made of gypsum plaster, a semi-hydrous form of calcium sulfate. The gypsum plaster is then combined with several substances including fiberglass or paper, and then mixed with water. This plaster-based mixture is put between two sheets of heavyweight paper or mats of fiberglass and then left to dry and harden. Once the mixture dries, it becomes strong enough to use in commercial and residential construction. Soundproof sheetrock is also known as soundproof drywall, sound-engineered sheetrock, and sound-engineered drywall.
How does soundproof sheetrock work?
Soundproof sheetrock works by absorbing the vibration of soundwaves before they have a chance to pass through to the other side of the wall and become audible. This process is called “dampening.” For example, if soundproof sheetrock is used to build the walls of a playroom for children, it will serve to block the noise of children’s play from disturbing people in the adjacent rooms, but it won’t do much for those below or above the playroom. However, if soundproof sheetrock is used to build the ceilings and floors of the playroom as well, the children’s play should not disturb anyone in the rest of the house.
How is soundproof sheetrock used?
Soundproof sheetrock can be used during construction and after construction. If used during construction, soundproof sheetrock can be used in place of regular sheetrock to build walls, ceilings, and floors. If used after construction, soundproof sheetrock can be applied directly on top of existing sheetrock using a special adhesive that also works to absorb sound.
Soundproof sheetrock is frequently used in the construction of commercial buildings, recording studios, single-family luxury homes, and multifamily residences where tenants share common dividers, like townhouses, apartments, and condominiums.
