![]() The ease of installation of this material, the cost and the non-toxic formula are all benefits that come with the use of mass loaded vinyl sheets instead of raw lead. With the introduction of mass loaded vinyl sheets, lead is no longer used. Prior to the introduction of MLV, raw lead sheets were used to provide a sound barrier to outside noises coming in. ![]() Adding soundproof material to the walls, floors, and ceiling of a media space has become a very common practice. To insulate the upper floors from the noise of the media room, MLV is used in the flooring or in the ceiling of the basement.Īcoustic quality of a theater is an absolute must. In construction today, many family homes are being constructed with media rooms in the basement and the living floors above. This soundproofing material can be applied to the floor as well to insulate from noises below and to insulate the floors below from impact noises such as children running or things being dropped. ![]() Size: 1x5m, 1x10m Thickness: 3mm, 1.2mm, 2mm thick mass loaded vinyl Mass loaded vinyl STC rating. Mass Loaded Vinyl Thickness & Specifications. This means that it is not difficult to install it on the floor and ceiling, and it can also be wrapped around the vent. However, if it’s not possible to add this during installation of the main walls, the alternative is to attach it to the drywall and either paint over it or attach it to the back of paneling and use finishing nails to attach the paneling to the drywall. High density mass loaded vinyl is like that. Ideally, attaching the mass loaded vinyl directly to the studs in the wall provides the best noise barrier. ![]() It does meet building code requirements for flammability ratings and is not toxic to the occupants of the building where it is being used. Because of its versatile characteristics, it can be used nearly anywhere. MLV is used as a soundproofing material in homes, businesses, hospitals, theaters, music studios and many other places. Some of those suppliers are Acoustical Surfaces, Inc., Sound Proofing America, Sound Isolation Company, Super Soundproofing Company, and Green Glue Company. Many soundproofing material suppliers now provide mass loaded vinyl to their customers. Damping may cause wall Fr to fall into the woofer’s pass band and increase “box talk”.American mass loaded vinyl (MLV) consists of a high-grade vinyl mat that has added to it barium salts and silica (sand) to give it the same effectiveness as lead sheeting but without the health hazards associated with raw lead. Box wall Fr and Q loss number lower than a well braced cabinet. Simplified design and construction, with increased net box volume vs. Resistance of wall panel is increased, lowering its Q and dissipating vibration through heat.Ģ. Fr of box vibration may not be raised above the crossover and the higher Q of the fr may produce more noticeable “box talk”.ġ. Added mass of bracing may largely offset the reduction in cabinet vibration, especially in a large cabinet.Ģ. Fr of box walls raised above the crossover of the driver occupying the box.ġ. Reduces cabinet wall vibration, lessening the through transmission of LF sound.Ģ. Without modeling software or a bit of trial and error, it’s all guesswork.ġ. In a large one, bracing may increase the Q and raise the fr of the cabinet walls right into the midbass range where it is most audible. Bracing on the other hand takes up as much or more internal volume in a small box. A vinyl tile is almost viscous (bend one and see) and resistive to vibration.
