Here’s a link to a detailed guide on the best MLV soundproofing barrier alternatives available on the market today. However, mass loaded vinyl and drywall can be installed together for maximum sound reducing capabilities.Īll you need to do is sandwich the MLV sound barrier between the layers of drywall. However, it can improve the STC ratings of a wall by up to 15-20 STC points while it would take up to 4 sheets of regular drywall.
This product isn’t your regular gypsum drywall. Quietrock Drywall sheets are the best alternatives to mass loaded vinyl.

Read my guide on how to hammer quietly so that you can make this whole activity quieter as possible. For 16” O.C (On Center) framing, you should hammer a nail and washer through the sound barrier every 24” O.C along with the top plate of all the studs.Use the pneumatic cap stapler to fasten every 8” along with the studs and top plate length.You should maintain an even gap along with both the ceiling and the floor. Get the assistance of another person and position the first sheet to the corner of the wall.Use the straight edge or T-square to cut the straight cutter and a utility knife to cut the sound barrier to length. Cut the roll of MLV to the desired size.Measure the distance between the floor and the ceiling and then subtract 1/8” -1/4” from the length.Pneumatic Cap Stapler Cap Staples, or Screws with Caps.Acoustic Sealant (read my complete guide on different acoustic sealants on the market).I would highly recommend one that contains polymeric plasticizers for added stability and strength over cheaper monomeric.Īdditionally, go with extruded MLV instead of the cast because cast MLV is quite prone to damage.
Unfortunately, not all MLV products are equal. When constructing soundproofed ceilings, walls, and floors, it’s essential to add a non-resonant mass. Unlike other materials such as acoustic foam panels, MLV can absorb vibrations/ impact sound waves. It can be stretched and return to its original shape. It’s a viscoelastic material that exhibits both viscous and elastic characteristics. MLV comprises two main ingredients polyvinyl chloride (vinyl/PVC) and barium sulphate or calcium carbonate. It’s also known as the Limp Mass Barrier. When attached to the walls and ceilings, it adds more mass hence attaining sound reducing capabilities. The main principle in soundproofing has always been more mass. Mass loaded vinyl is a heavy vinyl sheeting material impregnated with metal particles to increase mass.
