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)
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.
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.
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.
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.
No, mass loaded vinyl will not help to isolate impact footfall noise.
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.
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.
Attach grommets to the MLV to tie or fasten to chain link fences. Use standard drywall nails or screws for fastening to wood fences.
