One-part, nonflammable, latex base acoustical caulk designed specially for the reduction of sound transmission in all types of wall partition systems.
Whether you are building music studios, conference rooms, offices or any space that requires sound privacy, using multiple layers of sheet rock, mass loaded vinyl barrier and resilent channel is a great start to soundproofing. However, no matter how many layers comprise the wall composition, any air gap or a seam will allow sound to spill into or out of the room. This would render all your hard work and labor null and void as well as waste your construction budget. It only takes a very small space to allow a large sound leak. Wall board and vinyl sound barrier are simple to seal correctly using an acoustical sound caulk. Be sure to apply sound sealant to all vertical and horizontal seams as well as the joints at the floor, ceiling and both inside and outside corners. Wall switches and electric outlets also pose a threat to sound leakage.
They are just as important as the overall wall construction. Be sure to seal any of these weak spots with a solid enclosure or use a caulked vinyl sound barrier flap to create a soundproof seal behind these openings.
When Soundproofing a room, don’t forget to seal all your seams and gaps. If air can pass through, so can sound! http://www.acousticsfirst.com/sound-proofing-barrier-osi-acoustical-sound-sealant.htm
