Steps to Soundproof a Wall

  1. Measure the height of the wall. Roll out the MLV so the length of the material matches the wall's height. Cut the mass loaded vinyl using a sharp utility knife and a T-square to ensure you make a straight cut. You can also cut the MLV with a good pair of upholstery scissors. Just be careful you don't make crooked cuts!
  2. Fasten the MLV to the wall using staples, screws or nails. Start attaching the MLV at the top of the wall, and work your way across ensuring the MLV stays straight.
  3. The preferred installation method is to install MLV to a wall that has insulation and framing, but no drywall yet. There are a variety of installation methods that will improve performance, such as sound isolation clips or a double wall, but if you are not an experienced installer, we recommend to just focus on the basics, and ensure you have a sturdy install that is airtight and gapless.
  4. If the wall already has drywall, we recommend removing the existing drywall. If you choose to install MLV on top of drywall, it must be attached to the studs or joists. Drywall will not support the weight of MLV.
  5. After you've finished attaching the MLV to the studs and the bottom of the wall, repeat the steps you just did for your second cut off the MLV roll. Do not cover any wall outlets or light switches. Leave them exposed.
  6. As you work your way across the wall, keep the ends of the MLV directly next to each other. (AIRTIGHT!) If the MLV edges connect on a stud, use acoustic caulk to seal the gap. If the MLV edges connect over an air gap, use foil tape to seal the edges.
  7. After you've finished getting the MLV up on the wall, use your acoustic sealant caulk to seal ALL of the edges, both between the sheets of MLV and between the MLV and the wood studs. THIS IS A KEY STEP TO ENSURE YOUR BARRIER IS AIRTIGHT. If you have not hung drywall, now's the time to begin installing drywall on top of the MLV.




Have a Smaller Project? You should take a look at MLV Sheets.

Our Quiet Quilt line of sound blankets combine reinforced MLV with a vinyl facing for sound absorption and sound blocking. We also can put MLV inside a fabric wrapped panel to create a sound proof panel. Contact us for details.


Automotive Application Instructions

Recommended Install Adhesive: HH-66 Vinyl Contact Cement or Dual Lock Reclosable Fasteners (spray adhesive will not work on vinyl)

Install Locations: cabin side firewall, car floor, trunk, on top of wheel wells, and back wall to reduce road noise in car

  1. For best results, Luxury Liner should be applied on top of a sound deadener, such as Second Skin Audio's Damplifier Pro or Spectrum. It’ll be the final layer of your multi-layer sound insulation bubble.
  2. Choose your decoupler. For the floor of vehicles, we recommend OverKill Pro (closed cell foam) or Heat Wave Pro (jute material) as a decoupling material between the MLV and the application surface on the car. OverKill Pro adds water resistant insulation, whereas the Heat Wave Pro is an OEM style thermal insulator and sound absorber. Both options work well.
  3. If upholstery or carpet is not already out, remove it. Ensure there’s no loose debris, rust, dirt, or waxy oils.
  4. Cut Luxury Liner to the desired size with a sharp utility knife or a good pair of scissors. Be sure to cut to a size that will allow you to reinstall the carpet and upholstery trim. Do not cover wires, drain holes, or mechanical devices. This part of the project is more art than science, as you need to have as few gaps as possible in your noise barrier while avoiding interference with other parts of the car.
  5. Use vinyl cement, such as HH-66 Vinyl Contact Cement, to adhere the Luxury Liner to the decoupler of choice. Apply one coat on the Luxury Liner Vinyl and one to the decoupling product.
  6. Apply a second adhesive to the decoupler and the foil side of your Damplifier Pro. You can reuse the contact cement again or another one you choose. The decoupling layer should be attached to the foil side of your sound deadener. Apply constant pressure over the entire surface for several minutes to ensure a solid bond.
  7. Seal any exposed edges or seams with Foil Insulation Tape. The goal is to create as close to an unbroken noise barrier as possible.
  8. Factory carpet can be replaced immediately. Aftermarket carpet kits can be attached directly to the exposed mass loaded vinyl side of Luxury Liner.
