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. 7 On Mass Loaded Vinyl Soundproofing Why Is Mass Loaded Vinyl Soundproofing Important?
