If the surfaces are hard, those vibrations transfer back into a room raising the decibel level. Sound waves create vibrations when they make contact with a surface. Weight and thicknessĪpproximate decibel level it will be reduce The most common areas mass loaded vinyl is used is on top of grid ceilings to stop noise getting out and on walls either on the studs before drywall or in between sheets of drywall to stop noise penetrating through the wall. MLV can be attached to walls, on top of ceilings, around pipes, on fences. Mass loaded vinyl can be installed on virtually anything. When choosing a mass loaded vinyl, you must determine if the noise that is impacting you needs to completely disappear (difficult to do) or do you want to muffle the noise so it isn’t as bothersome. This can range from sound moving through a wall into another room to noise from pipes transmitting into the surrounding area. Mass loaded vinyl will directly stop sound moving from one area to another. When deciding which Silent Wrap mass loaded vinyl is best for you, keep in mind that the rating is the reducing capability, not the end result. Loosely translated, the STC number is the number of decibels that can be reduced.
STC stands for Sound Transmission Class and is a laboratory test to determine the effectiveness of a product’s ability to block noise. Each thickness has its own noise-blocking power or STC rating. ¼” is also the heaviest weighing 2 lbs for every square foot of material. ¼” is the thickest mass loaded vinyl we offer and produces the max noise-blocking available. 1/8” is the most common and weighs 1 pound for every square foot. 1/16”, or half-pound weight per square foot is the most economical. Our Silent Wrap mass loaded vinyl is available in different thicknesses, 1/16”, 1/8” and ¼”. Mass loaded vinyl is a heavy sheet product, in comparison to its thickness, made of a type of vinyl that is supplied rolled up. Unlike drywall, metal, or wood, SilentWrap™ is a flexible, yet dense polymer barrier manufactured from post-industrial recycled content.
While it is a very thin product, it reduces the transmission of airborne noises by adding mass to the structure to which it is applied. SilentWrap™ is a flexible Mass Loaded Vinyl Acoustic Barrier that can be used to dampen sound and vibrations in walls, ceilings, HVAC ducting, and anywhere noises need to be arrested.
