MASS LOADED VINYL STC INSTALL

0 dB is near-total silence, while sounds over 85 dB can cause hearing damage or loss. The decibel is figured by determining how loud a sound is, in relation to how far away from your testing area it is. The decibel, or dB, is universally used to measure the intensity of a sound. There are three main terms to understand when understanding STC. Simply put, this means that STC measures how much sound is lost when traveling from one side of a wall, floor, or ceiling, to the other side. STC is an integer rating of how well building partitions reduce airborne sound. It is one of the original ways to determine how much sound materials block, and is still considered to be one of the best ways to determine sound transmission loss. Ideal for duct systems running over conference rooms, class rooms, offices, sound studios, and hospital rooms.Sound Transmission Class, or STC, was first used in 1961.

Used to wrap noisy pipes, ducts, valves, and fan housings.

NOISE TRANSMISSION LOSS (dB) / FREQUENCY (Hz) HERTZ

Any gaps left exposed will reduce the structural STC rating, and create a noise channel through that opening. Caulk all gaps and spaces that are left exposed with Sound SealR Sealant, especially the space between the ceiling and the MLV as well as the floor and the MLV.(cut out overlapping material on top and bottom of studs so drywall is not uneven when installed over the MLV. Use a strip of SealR tape to vertically seal the overlap joint. (first put the strip of tape on the underneath peice of MLV and pull forward before tightly taping to the overlapping piece of MLV.) Once the space between the overlap joint is reduced use a large bead of MetroFlex Sound SealR sealant inbetween the overlapping pieces. Smooth out the Sound SealR Sealant so it is flush with the MLV and seal up with MetroFlex SealR Tape.ī) When two pieces of MLV do not meet on a stud, overlap the two pieces of MLV (approx 2"-3") and use small strips of MetroFlex SealR tape to horizontally tape the two pieces together every foot.

Then use MetroFlex Sound SealR Sealant to seal the gap on the stud. A) When two pieces of MLV meet on the stud, cut the pieces so they meet flush in the middle of the stud (do not overlap on a stud).

(attempt to have joints land on studs when possible).

The width of the material is 48", which will cover 2 sections of 24" wide framing or 3 sections of 16" wide framing.

Measure the height of the wall and cut the MLV the height of the wall with a razor knife.
