![]() The polymer is an extruded Polyvinyl Chloride (PVC) which is “mass-loaded” with a cheap filler, typically Calcium Carbonate or Barium Sulfate. ![]() Some of the trade names include MLV Blokker, TuffMass, AcoustiBlok, and Vinaflex, but many others are similar or equivalent. Standard Mass Loaded Vinyl is known by many trade names, though it is largely the exact same product extruded from the same few manufacturers in the US. double-studs or resilient channel), but can also be effective in industrial settings. 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). While effective in many assemblies, it may not be as effective in others. First and foremost, it should not be considered a “panacea”. These are environments where sound control is critically important, and our cost-effective MLV material lowers the total cost of building and construction than installing multiple drywall layers or pouring additional layers of concrete flooring.What makes Mass Loaded Vinyl (also known as MLV) effective and what are its limitations? While it’s been around for several decades there is still a lot of misinformation about MLV within the construction industry. It can even be nailed through with large head roofing nails, and this could be done as the vinyl adhesive sets and cures.Īpplications for residential and commercial use include home theaters, music rooms, bedrooms and basements, multi-family developments, recording studios, hotels, educational facilities, places of worship, theaters and performing arts centers, healthcare facilities, and financial institutions. It is often stapled to the studs prior to hanging the drywall, but if you are retrofitting an existing wall or surface, you can simply glue the soundproofing barrier to the intended surface with a vinyl construction adhesive. This material is designed to be used in walls, floors and ceilings. You can use this mass loaded vinyl for noise reduction in your soundproofing construction. Dense, yet flexible, mass loaded vinyl greatly improves sound transmission loss (STC), but without losing valuable space. There are lead fillers in this soundproofing material. These sound and noise barriers are dense, but at 1# per square foot, still lightweight enough to handle. Mass loaded vinyl helps create exceptional sound blocking assemblies to reduce sound transmission for retrofit/ remodeling and new applications. It can be combined with acoustical foams, glass fiber, ceramic fiber insulation, and mineral wool to provide efficient and lightweight composites with high transmission Its many attributes are it offers strong resistance to adverse environmental conditions, including oils, weak acids and alkalis. Designed to be placed within walls, under primary flooring, or positioned above ceilings, our mass loaded vinyl can even be hung as soundproof curtains. Our mass loaded vinyl is an exceptional soundproofing material and it will not shrink, cause metal corrosion or rot. It is ideal for direct application to the noise source and/or to the housing covering the noise source. Our Mass Loaded Vinyl is a flexible sound blocking barrier, and non-reinforced vinyl that reduces the transmission of airborne noise and resists the passage of sound waves.
