Although a 5 STC point difference is generally a doubling effect to the human ear, the actual gains can be more significant, or less significant, depending on the exact frequency. The standalone STC rating of each of these thicknesses/weights jumps about 5 points as the material thickness increases (STC 20, STC 26, STC 31). A quick search online and you will find numerous tape options at every cheap prices. Sheathing tapes are generally polypropylene with acrylic adhesive. If your project requires the use of seam tape, then we recommend using sheathing tape to adhere best to our mass loaded vinyl. The largest gains from MLV are experienced in walls, doors, windows, and other odd areas like around pipes, duct work, in curtains, in cars, and hanging on exterior fences. MLV is an acoustically dead material that will bring a value, sometimes big and sometimes small, to any assembly. It doesn't rely on an assembly with particular spacing for framing, or common walls, or existing drywall, or certain finish floors, etc. One big advantage to MLV is that it works essentially anywhere. However, TotalMass MLV Sound Barrier still has its place in sound isolation. With advances in technology, higher-rated products have been introduced, providing more cost effective alternatives in walls, ceilings, and floors. For some time, it was considered the best solution for a number of sound issues.

Mass loaded vinyl (MLV) is one of the original sound isolation products.
