This makes it suitable for fixing various kinds of floors and walls.Ī room may have pillars or pipes that will interfere with the flooring materials. You can bend, twist, and wrap MLV the way you want. The flexibility of MLV makes it distinct from the other soundproofing options. Here are some of the reasons why you should opt for MLV underlays: Flexibility However, its properties make it a winner when it comes to noise reduction. MLV holds the reputation of being one of the most effective materials for soundproofing. Benefits of Using MLV for Carpet Underlays We recommend you read the instructions in the manual before you begin the painting process. MLV is available in transparent and translucent forms. You have to choose a latex paint of the color that you want. You can paint MLV to a color of your choice if you believe it is compatible with the color of your carpet. Once you get done, you should seal the space between different segments of the MLV. It is essential to understand that this method is a permanent fixture of MLV. Once MLV is placed accurately, you can move to carpet installation. Also, consider applying soundproof compounds like Green Glue to enhance the noise reduction effect. The last step is to tack MLV in place using finishing nails and staples. This makes the installation more manageable. If the room is large, you can lay it in portions compared to one whole piece. Make sure that you maintain a 1/8” to ¼” gap at the edges of the floor. You may need a hand as you hang the sheets. Step 2 – Align the SheetĪlign your sheet along the corner of your floor frame. You can also use MLV with heavy-duty scissors. Once you have marked the edges, it comes apart. There is no need to cut through vinyl entirely. Use a utility knife to cut an even square edge across the vinyl sheet. Measure the floor from one point to the other. Mass is the crucial component in sound control and works by stopping sound from vibrating within the structure. Mass Loaded Vinyl (MLV) is easily applicable on floors, ceilings, and walls to create a sound barrier. This guide enlists all the measures to take when installing MLV under carpets. It is essential to enhance your awareness when you consider installing MLV at your place. Meanwhile, the material’s elasticity ensures it stays stable after confronting the vibrations. The flow effect is necessary for materials to absorb vibrations. It exhibits a flow effect when vibrations come into contact. As the weight changes, the density and thickness will also modify. The most common weight for MLV is 1 lb/SF. They commonly vary between 0.5 pounds per square foot to 2 pounds per square foot. Mass Loaded Vinyl (MLV) is available in a wide range of thicknesses and weights. As for airborne noises, other soundproof materials like foam panels can work efficiently. MLV works excellent to reduce structure-borne noises. In fact, it amplifies as it passes through walls and floors. It is called “structure-borne” because it is easy to pass through. Impact noise is the low-frequency sound produced by engines, television, drums, or kids jumping around. Metal Particles impregnate MLV, whose main aim is to amplify the mass of the material.Īn essential purpose of MLV is to dampen structure-borne noise or impact noise. MLV is also called the Limp Mass Barrier. It works as a potent sound absorber and a functional sound barrier. What makes MLV an incredible choice is its double threat feature. Vinyl – adds flexibility to the material.Calcium Carbonate or Barium Sulfate – dense compounds that provide soundproofing capabilities.MLV is the mixture of two main components: All fasteners must be affixed directly into the frame, flush with the structure.Final Thoughts What is Mass Loaded Vinyl (MLV) Used For? Do not rely on drywall alone to support the barrier. Start with several fasteners at the start of the roll before allowing to hang. A wide head fastener, such as a cap stapler, screws with plastic washers, or roofing nails assists greatly with weight distribution. Using the right fasteners helps reduce the chances of the barrier tearing under its own weight. The final result should be a flat application of the material. If you are putting barrier on existing walls, find the studs/joists and mark them. Because of the stud or joist behind the seams, you can put pressure on them. If installing on bare stud walls or ceiling joists, install parallel to framing (vertically on wall studs). – Between layers of drywall, plywood, plaster, etc. Noise Barrier can be installed over existing wall or ceiling surfaces or directly to wood/metal framing.
