![]() As shown in Figure 1, let us assume that an acoustic wave can be represented by a single degree of freedom oscillator, with a single peak of high amplitude (shown in red). In order to understand how MLV attenuates sound, we need to first make an analogy with the field of mechanical vibrations. Transmission Sound Barrier/MLV-FAQs Figure 1 How does MLV work? -Sound Barrier/MLV-FAQs Because it’s so heavy, Fcoustic MLV should be adhered with an extremely strong adhesive (like acrylic tape or vinyl cement) or fastened with screws, staples, nails, or reinforced grommets. It’s extremely effective for home or commercial use as well, and often used to reduce noise transmission in in soundproofing ceilings, floors, walls, machinery enclosures, ductwork, a generator sound box, to soundproof a door, and even to build a DIY sound barrier fence. One of the most common uses for MLV is soundproofing walls.īecause Fcoustic mass loaded vinyl is flexible, it’s the ideal noise blocking material to fit around the contours of a vehicle. It’s most often bought in large rolls, but Second Skin also sells sheets because they’re much easier to ship and some projects need less square footage.Fcoustic MLV is odorless, heat resistant, waterproof, tear resistant, and has a high STC rating for effective noise blocking. Mass loaded vinyl is typically colored black with a density between 3kg to 6kg per square meter. Manufactured from Pure White PVC vinyl that has been compounded with inert materials to increase density, MLV is well suited for automotive, industrial, and building applications. Safer than lead and denser than drywall,Fcoustic mass loaded vinyl is a high density, limp material that’s engineered to be an effective sound barrier. The simplest way to think about it is this: The heavier the material, the better the soundproofing quality.ġ000mm*5000mm*3mm or 1000*10000*2mm/1.2mmĢ.1kg/sqm for 1.2mm and 5.6kg/sqm for 3mm and 3.7kg/m2 for 2mmįcoustic Mass loaded vinyl (or MLV) is an acoustical barrier that blocks sound wave transmission to provide excellent noise reduction. These are measured with different STC ratings, which you can read more about here. Outside of how much they weigh, or the size, different weights of Fcoustic MLV have different degrees of sound blocking capabilities. ![]() This correlates to the thickness of the material, but since Fcoustic MLV is produced to a precise weight per square meter, there might be slight variances in the thickness. Fcoustic NEW white Mass Loaded Vinyl is a safe, non-toxic, odorless barrier designed to hang as a limp mass in a variety of soundproofing applications.Īll Mass Loaded Vinyl is measured by weight, specifically, pounds per square meter. MLV has been used for soundproofing purposes dating back to the 1960s and is still considered to be one of the most effective sound-blocking materials on the market. The weight of Fcoustic MLV is the product of infusing the PVC vinyl sheet with a calcium carbonate, which gives MLV its density while retaining flexibility. Mass Loaded Vinyl, commonly known as MLV, is a heavy, PVC vinyl sheeting material that is used to stop sound transmission. This Fcoustic Sound Barrier/MLV is our attempt to dispel any fiction about Mass Loaded Vinyl (MLV) and give you the facts in a FAQ format.įcoustic Mass Loaded Vinyl is the material of choice for use as a sound barrier.
