Mass Loaded Vinyl Soundproofing

For decades, soundproofing mass loaded vinyl has become the industry standard for noise control. Although this material has many trade names, they are all simple PVC sheets with barium sulfate or calcium silicate on them to increase weight. The mass loaded vinyl soundproofing material is very dense, weighing one pound per square foot. This quality enables mass loaded vinyl for soundproofing to effectively reduce airborne noise. Mass-loaded vinyl sound barrier can be used as a barrier for walls, floors and ceilings, thereby significantly increasing the quality of these surfaces, thereby reducing noise.

In addition, mass loaded vinyl noise eliminator can be used as an insulating material to wrap metal pipes, plastic pipes, steel columns, etc. This is extruded mass loaded vinyl, not cast. Compared with extrusion, MLV casting is easier to tear and more difficult to install. It has:

High tear strength
Sound transmission is significantly reduced
Large, soft, flexible, formable and versatile

Mass vinyl soundproofing is traditionally “loaded” with barium sulfate. Today, this situation is not so common, and most MLVs are made of calcium silicate. Although it is still common to see “barium-loaded vinyl” in building codes, the fact is that barium is almost no longer used as a filler.

Soundproofing mass loaded vinyl is generally described as “1/8” and “1 pound per square foot”. “This is just a general description. When comparing various samples from different manufacturers, it turns out that none of them are actually 1/8 inch and most are not 1 pound. This is made, specified and sold here in the China. The 1/8″” size is only part of the informal description for industry use. The weight of the mass loaded vinyl for soundproofing will change +5%. We manufacture according to weight standards, not size standards. Usually, the weight is 1 pound + 5% per square foot.

We introduce these products and construction concepts on the premise of understanding local building codes. The installer of mass loaded vinyl for walls is responsible for ensuring that the mass loaded vinyl noise eliminator is installed correctly and that these concepts comply with local building codes.
