![]() ![]() Wondering where to buy mass-loaded vinyl locally? On the other hand, EVA membranes don’t require plasticizers and are naturally pliable. Unfortunately, plasticizer breaks down with time, and they off-gas at room temperature resulting to unpleasant odors PVC is naturally rigid, and so an additive known as a plasticizer is then added to give it flexibility. When it comes to MLV sound barriers, there are two main polymer bases- they include Ethyl Vinyl Acetate (EVA) and PolyVinyl Chloride (PVC). In the past, additives such as barium-sulfate and lead were used. The liquefied polymer is then mixed with additives, the most common ones being calcium carbonate. To create MLV barriers, a polymer is extruded at high temperature and pressure through a screw and chamber. So, in reality, 2 psf is 1/4″ thick while 1 psf Mass Loaded Vinyl is 1/8″ thick. They range between 0.5 lbs/sqft to 2lbs/sqft, with the most common ones being 1.0lbs/sqft.Įven though the weight constantly changes, the density rarely does, but thickness does change. MLV sound barriers are available in different thicknesses and weights. What are the Types of Mass Loaded Vinyl Soundproofing? However, mass-loaded vinyl gives a great soundproofing power when combined with other soundproofing materials, including drywall soundproofing, sound clips, etc.īesides construction soundproofing, mass-loaded vinyl is also highly effective in soundproofing air conditioner compressors, numerous industrial applications, noise deadening home entertainment systems, and even soundproofing radio stations. MLV serves as a sound barrier regardless of which side of the wall you install it on. Therefore, this helps keep noise inside a space or outside a space. It doesn’t absorb sounds like soundproofing paint or acoustical wallpaper, but instead, it blocks or contains sound waves. Mass-loaded vinyl soundproofing is a “reflective barrier” rather than an “absorptive barrier” like acoustic foam panels. If you’re regularly troubled by noise from your neighbors’ yard, MLV will help you block the yard noiseĬheck Latest Price How Does Mass Loaded Vinyl Soundproofing Work? If you’re a DIY soundproofing person, then the MLV sound barrier is one of the best options you’ll find. Mass-loaded vinyl sound barriers can block most of the everyday noise you encounter, ranging from construction sounds, traffic noises, and even noises from buses, trains, or aircraft. Once the acoustic sealant/ caulk is applied, the seams must be taped for maximum soundproofing performance. ![]() It’s simply attached to studs or joists and then followed by covering seams and joints with a barrier or acoustic caulk. MLV barriers are made of salts, tiny metal particles and sand that enable product to reduce noise without the stigma attached to lead materials. It’s a greener and more reliable substitute to lead soundproofing. Mass-loaded vinyl is quite affordable, easy to install, and an effective soundproofing option that blocks airborne and impact noise. I got plenty good enough for about £1.5K and a day and a half of DIY for the whole floor area of a London Victorian terrace house.7 On Mass Loaded Vinyl Soundproofing Why Is Mass Loaded Vinyl Soundproofing Important? I'd do exactly the same again if faced with a similar situation.įor sure there are more effective solutions, you could get a quote for £20K and it would be perfect. Well worth doing, it didn't break the bank, easy DIY that didn't take long and seems to be effective. Haven't heard a peep from downstairs neighbour and she's never complained. I got carpet underlay with the highest acoustic rating I could find then good quality carpet. All this sealant rubber mat and tape is to make the floors as airtight as possible. New skirting boards on top of the MLV with more acoustic sealant beneath and behind them. Taped the edges then laid another layer of it with the seams running perpendicular to the layer below, taped the seams again. I did a bit of research and ended up removing all the skirting boards and sealing all the gaps around the existing chipboard floor sheets using acoustic sealant (I didn't pull the floors up).Īfter this I laid a layer of 2.5mm Mass Loaded Vinyl that you just roll out and is easily cut with a Stanley knife. I wanted to do something to soundproof my floor so I wouldn't disturb the flat below before I moved in to a flat I'd bought. ![]()
