ACOUSTICAL CAULK: Acoustical Caulk is a non-hardening, sound absorbing material with the active ingredient of Ethylene Glycol. Silicone is not an acoustical caulk so please do not buy for a soundproofing project. Acoustical Caulk is used at the seams and perimeter of the American Mass Loaded Vinyl. | |
|
AMERICA MAT: A closed cell foam that is both acoustically absorbent and fire proof. The America Mat is a valuable material for use in applications requiring maximum sound reduction. The America Mat is used often in automobiles, planes, and boats to reduce the amount of noise. |  |
|
AMERICA SEAL SEAM TAPE: A vinyl tape for sealing the seams of the Mass Loaded Vinyl. This material sticks very effectively to the American Mass Loaded Vinyl. | |
|
AMERICAN MASS LOADED VINYL (MLV): A reflective barrier material that weighs one or two pounds per square foot. This material is used primarily for blocking sound through a partition such as a wall or floor/ceiling. It is rated at 26 STC points in the one pound variety and 32 STC points in the two pound version. |  |
|
AMERICAN SOUND ISOLATION TAPE: A 1-7/16" wide closed cell foam tape perfect for stud and joist isolation. Provides a substantial decibel reduction over bare studs and joists. This product is an alternative to floating a wall or ceiling and is effective at stopping drywall to frame sound transmission. |  |
|
FURRING TRACK: This is a metal channel that is inserted into the sound clip. Drywall is then attached to this channel with drywall screws. The dimensions of this channel are as follows: the width across is 2 3/8", the length is five foot and the channel is either 7/8" or 1" deep. | |
|
SOUND CLIP: A sound clip is a metal and rubber isolator used to create a "floated" ceiling. It is used in conjunction with metal furring channel and 5/8" fire-code drywall to create a new, separate ceiling that provides true separation from your ceiling joists. | |
|
STC (SOUND TRANSMISSION CLASS): An STC number is the average number of decibels of sound stopped by a particular material from passing through a partition. | |
