## Overview

Premium Quality MLV Seam Tape is a 6 mil thick, 1.5-inch wide, 108-foot long vinyl tape designed specifically for sealing seams and gaps in mass-loaded vinyl sound barriers. It offers heavy-duty adhesion for durable, long-lasting soundproofing performance, covering up to 200 square feet per roll. Ideal for both professional contractors and DIY enthusiasts, this tape ensures a clean, efficient installation that enhances noise reduction by preventing sound leaks along MLV seams.

## Description

Experience the ultimate in noise reduction with our Soundproofing MLV Vinyl Acoustic Sealant Tape. This high-performance tape is designed to effectively insulate MLV seams and gaps in your soundproofing assemblies, providing you with a quiet and peaceful environment.Whether you're a professional contractor or a DIY enthusiast, our seam tape makes the installation process a breeze. Made from durable black PVC, this seaming tape is built to last. It ensures long-lasting performance and reliability, making it a valuable addition to your soundproofing projects. Its versatility allows it to be used for other purposes like sealing gaps and insulating spaces. Whether you're a professional contractor or a DIY enthusiast, this tape is a must-have tool in your arsenal.

Review: I Used It on The Seams - Thin. Not much mass. Sticks pretty well to MLV sheets. It's just like wider electrical tape. It stretches and is black. I didn't test before and after to see if there was any measurable difference but sound wall instructions say to use a quiet barrier seam tape on seams. The bulges are nails and screws underneath it. All the white caulk on nail heads and seams (underneath tape) is Liquid Nails Acoustical Sound Sealant. It's cheaper than OSI SC175 and performs comparable.
Review: Probably not required but the right thing to do; don't stretch it! - I used this tape to seal the seams of sections of 2 pound/sf Mass-Loaded Vinyl. It's probably not absolutely necessary but it's the right thing to do, especially if you have THAT many seams (I installed everything myself and can't hold more than 20 pounds of floppy MLV with one hand while trying to staple it with the other ... while on a step ladder!). I don't think any instructions came with the packaging but it bears to note: DON'T STRETCH THE TAPE! Just lay it on loose (no bubbling or pleating, obviously). If you stretch it while you lay it down, expect it to peel off within a minute or two. It's just not how it works. I covered everything up with acoustic panels for aesthetic as well as functional reasons. The noise levels dropped dramatically (about 10db or about half as loud as before). Remember, the MLV is doing the heavy lifting here (and to a lesser extend the acoustic panels). The tape's role is relatively insignificant ... but so is its price. Just one roll was more than enough for a 16x8 wall with seams every 4 feet horizontally and 2+ feet vertically ... so around 75 linear feet of seams.
