You should also consider investing in quiet drum sets and recording equipment to minimize noise as possible. If you have a recording studio or a drum room at home and would like to prevent noise from leaking in or outside the room, I would highly recommend this product. Soundproofing Doors and Windowsīecause of its mass, MLV will enhance the noise blocking capabilities of both doors and windows. A-List of Mass Loaded Vinyl Usesįor DIY soundproofing enthusiasts, the MLV sound barrier is used in different applications. Green glue alone gives an STC rating of 55, while MLV gives 51 when limply hung and 52 when sandwiched. Green Glue is also cheaper compared to MLV and much easier to apply.Įven though hanging MLV limply is much easier, sandwiching it between a layer of soundproofing materials such as drywalls improves its performance.īelow is a chart that details how green glue outperforms MLV in terms of STC class. However, its effectiveness is much lower than that of the green glue compound, especially at low sound frequencies. Is Mass Loaded Vinyl Better Than Green Glue?Īccording to an article published on the TMSoundproofing website ( Source), mass loaded vinyl does improve wall performance in noise reduction. 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. Use the acoustical Sealant to caulk the seams to achieve the best sound isolation results.Repeat the steps from 1-6 for the entire wall.Next, use a razor blade to cut the opening along the edges of the box. Find all the electrical outlets and gently press the MLV sound barrier against the box.

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.
