MLV is most useful on steel-stud walls that can benefit from some additional weight while not needing significant decoupling or dampening (i.e. This is why a single layer of mass loaded vinyl can block as much sound (measured in STC rating) as 2-3 layers of drywall. This provides a thin, flexible membrane that adds significant mass to the wall (hence the name), but also adds flexibility to the partition. Mass Loaded Vinyl is simply an vinyl plastic that has heavy particles loaded into it during formulation, such as Calcium Carbonate (or in previous years, Barium Sulfate and Lead).

Use of MetroFlex SealR tape is highly recommended to help keep "in cavity" joints together and air-tight.ĥ. If the joint happens to fall within a wall or ceiling cavity, add a large bead of Sound SealR sealant between the overlapping sections along with second bead along the joint. Once the sealant is fully dry, add a strip of 4" wide SealR tape over the seam.Ĥb. It is recommended to have all joints fall on a stud or ceiling joist.

The width of the material is 48" which will cover 2 sections of 24" on center framing or 3 sections of 16" on center framing.ģ. Try to use as big a piece as possible to limit the number of joints.Ģ. Measure the height of the wall or length of ceiling and cut the soundproof vinyl into sections with a razor knife.
Roll Size: 4 ft wide x 12.5 ft long (50 sf)ġ.
Mass Loaded Vinyl Sound Barrier Insulation 1/8" Thick (1 lb/sf) has an STC rating of 27 which almost performs better than a 2" x 4" wall with 5/8" drywall on each side of the wall. In walls, ceilings, floors, on machinery, household appliances, around pipes, exterior fences, doors, as curtains to divide a room or over a window, and so on.
