It can also help you soundproof walls, ceilings - you name it, you can probably attach MLV to it. Mass loaded vinyl is a fantastic soundproofing material, whether you want to use it under or over flooring surfaces, or even under the subfloor. So even if you didn’t have insulation under the subfloor, it wouldn’t matter. If you’re worried about airborne noise, MLV can thicken up your floor. Before you go in with softer padding, you should consider laying mass loaded vinyl directly on top of your subfloor. I'll probably purchase the thicket stuff and lay it down and let the carpet installer just put down their standard underlay on top of it.Ħ. Here is some info I found online prior to posting here which gave me the idea. The reason I thought about using it for carpet is although expensive it is effective. The different the MLV made in the panels is amazing. I once owned a truck that had 2, Gigahertz of power going to 14 speakers. Yeah I've used MLV quit a bit in the past in my cars as well. Remember, those who sell to you, do not have your best interest at heart. I have not really looked into it more than that, but I would highly recommend testing your hypothesis before spending the money. I know for panel loading, there is a 1/3 rule which is to say anything over 1/3 and the returns diminish substantially. The thing with mass loading, is that is it is not a cumulative function where more is linear to better. Tarkett sells a mass loaded PVC with a rubberized/foam backing that claims it reduces sound transmission by 6? dB, I know it is heavy and I suppose it must work or someone smarter than I am would have called them on it. I am not positive how well it would work under carpet and padding and would be leery of anyone that told me it would work. I will say, where open air exists and you are trying to reduce transmission it works rather well. I have mass loaded door panels in my car to reduce the vibration they create when someone pumps, oh i dont know, 1200 W RMS of mid bass into them. It is a great way to prevent sound amplifications from source. As opposed to reflection reductions that dissipate soundwaves (vibration) mass loading "absorbs" them and does not let the energy transfer from, in this case open air, to the wooden structure of plywood subfloor/joist/drywall and back to open air where it will be head once more. 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.Mass Loading is a form of sound proofing that works by retarding the vibration transmission from one surface to the next. 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. 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. 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. 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.
