TotalMass MLV

The Basics

What is the thickness and weight of mass loaded vinyl?

1 LB: 1/8″ thick weighing about 1 LB per square foot (~105 pounds per 100 square foot roll)

2 LB: 1/4″ thick weighing about 2 LB per square foot (~210 pounds per 100 square foot roll)

What is the difference between TotalMass MLV and other brands of mass loaded vinyl?

Most likely nothing at all. Whether the MLV is name brand or private label, the manufacturer is often the same. There are slight differences in flexibility depending on the manufacturing process. Despite this slight difference, the pounds per square foot and resonance response (performance) does not change.

Where should I use mass loaded vinyl?

Technically anywhere you would like. There are other products that are less costly and more efficient in isolation that we suggest for most wall, ceiling, and floor assemblies.

Because of this, we often only recommend mass loaded vinyl in lightweight assemblies with minimal layers of material, or for utility use in fences, doors, windows, duct, cars, etc.

How does mass loaded vinyl help to isolate in walls and ceilings?

When used in a framed structure, any benefit created by mass loaded vinyl is not from the actual mass itself. The structure already weighs several pounds per square foot more than the MLV. To increase isolation considerably with mass alone, the material would need to double the structure weight.

What MLV brings to the assembly is a material that resonates like no other building material. Every structure or material has a resonance point. Including mass loaded vinyl in the structure will resolve many resonance issues allowing consistent performance in mid to high frequencies.

However, using different thicknesses of materials for drywall or wood layers, or the inclusion of Green Glue Compound between layers, will also resolve these common resonance issues.

 

Is mass loaded vinyl better than other products?

More recent advancements in sound isolation with resilient sound clips, damping compounds, and rubber underlayment minimizes the value of mass loaded vinyl in a framed structure. However, where these new products cannot be used, the mass loaded vinyl likely can. Including fences, doors, windows, duct, cars, and other similar uses.

Will mass loaded vinyl isolate footfall noise?

No, mass loaded vinyl will not help to isolate impact footfall noise.

Installation

How do I fasten to walls or ceilings?

Basic drywall screws or nails with a thin washer or roofer’s tin cap between the head of the fastener and the vinyl. Staples can also be used for even faster installation.

How do I install mass loaded vinyl in floors?

Roll it out, butt the seams together, and tape the seams with standard duct tape. MLV is not rated as an underlayment so finished floors such as tile or vinyl cannot be adhered directly to the MLV.

How do I install mass loaded vinyl on fences?

Attach grommets to the MLV to tie or fasten to chain link fences. Use standard drywall nails or screws for fastening to wood fences.
