Understanding Mass Loaded Vinyl

Mass loaded vinyl, otherwise referred to simply as MLV, was first introduced to the soundproofing industry as a replacement for lead sheeting. Lead sheeting had been the soundproofing agent of choice for several years but, as we all know, lead was later determined to be a toxic agent and the need to find a replacement product became imperative.

The standard mass loaded vinyl product is made out of a combination of sand and salts. This combination gives it a set of characteristics similar to those found in the original lead sheets but without the potentially dangerous side effects.

The purpose of mass loaded vinyl is exactly as it sounds. It is used to add mass to an area, thus making it more difficult for sound to pass through walls and ceilings. It’s a popular soundproofing agent, especially when it comes to soundproofing personal spaces such as homes or music studios.

The introduction of mass loaded vinyl products to the soundproofing industry had astounding results. It was not only a safe alternative to lead but was easier to use and apply. The sections are usually attached to the studs or joists of the area in question and then the seams around the edges are covered in acoustical caulk. After the caulk is applied the seams are taped over, ensuring that the seals are completed and that no sound will pass through.

Mass loaded vinyl products are not only easy to use but look great, too (though not as if you’re going to see the mats after they are sealed into the wall). They’re amongst the most effective soundproofing products available on the market today, creating a reflective barrier rivaled by none. The only alternatives to mass loaded vinyl or lead sheeting is fiberglass insulation – another material now frowned upon in the construction and soundproofing industry – or something similar to Green Glue.

Mass loaded vinyl products are great not only for the home but for businesses and commercial studios as well. They have the ability to block not only everyday noises caused by day to day living but significant sounds caused by high-traffic areas as well. These include aircraft carriers, trains, highways, and much more.

This incredible soundproofing product is not only a great soundproofing agent but is cost effective as well. The materials themselves are relatively inexpensive and even if you have to hire someone else to do the installation you’re likely to pay much less than you would if you were to have a lead-based soundproofing agent installed.

    Can green glue be used between two layers of mass loaded vinyl? If yes, what soundproofing results can be expected!

    That is not recommended. Rigid layers like drywall or plywood are the best materials to use for a constrained layered system like GG.
