Vinyl is one of the most often used soundproofing materials availble, probably second only to Green Glue. Also known as Mass Loaded Vinyl (MLV), the material works based upon the principle that sound can not pass through dense surfaces.
But here’s the problem. Mass loaded vinyl adds a little bit off mass to a surface, but only a pound or two per square foot. Consider a bad sound problem, and that doesn’t seem like nearly enough to get the job done right.
