Soundproofing homes, offices, and personal vehicles have become the latest lifestyle change across the world. With more companies manufacturing durable and sound absorbent products, the rise in their consumption has increased. When it comes to soundproofing, MLV or mass-loaded vinyl is the go-to option for soundproof interiors. The best thing about MLV is the considerable amount of mass contained in the minimum thickness. Essentially mass-loaded vinyl is a viscoelastic material that uses the property of hysteresis to diminish the noise inside the space.
To put it simply, the MLV dampens out the sound by flowing when the force is applied. But it goes back to its original configuration once released. Besides, MLV works in multiple places, including walls and ceilings and even for noisy plumbing lines—chiefly designed to absorb airborne noise. This product, which has anti-vibration properties, functions better for mid to high-level frequencies than lower frequencies.
When it comes to soundproofing, Second Skin MLV123 and Soundsulate MLV4 offer impressive features tailored to diverse needs. Second Skin MLV123 stands out with its choice of two densities, ensuring versatility for various applications. Its 1 lb variant, at 1/8” thickness, delivers an STC rating of 26, ideal for general soundproofing needs. For more demanding environments, the 2 lb version, with a 1/4″ thickness, offers an enhanced STC rating of 32, showcasing its superior sound-blocking capabilities. Additionally, its fire-resistant properties and high tensile strength, over 600 psi, make it a reliable choice for automotive applications, with a commendable temperature tolerance of up to 150 °F (175 °F intermittently).
On the other hand, Soundsulate MLV4 emphasizes flexibility and environmental safety. With a standard 1 lb./sq. ft. density and a .100” thickness, it achieves an STC rating of up to 29, suitable for reducing airborne noise in homes and buildings. Its non-toxic, odorless nature, combined with a broad temperature range of -40°F to 180°F, makes it an excellent option for diverse settings.

Working of MLV
The working of MLV is very similar to what happens when a ball is thrown at a hanging piece of cloth. Here, the ball falls a short distance away after touching the fabric. The textile part flows three-dimensionally and absorbs some of the energy left in the ball. Had it not flown, the ball would have bounced right back. When sound waves hit a surface like the walls or the ceiling and revert, the absorbed energy produces a vibration in the respective characters.
Now, the MLV installed between drywalls inside the wall absorbs energy. When the sound hits this MLV sheet, the ball-cloth effect comes into play. MLV is nestled against studs that allow it to move freely in the 3D space and helps reduce the absorbed energy, which leads to excellent noise reduction.
Advantages of using MLV
The advantages of using MLV are many. Compared to other soundproofing products, mass-loaded vinyl is thinner and lighter. They are easy to install and used in different parts of your interior. The flexibility of this material increases as this property depends on the thickness of the products. Unlike other soundproofing materials like drywall and acoustic panels that are hard and rigid, MLV is slightly elastic.
The simplest way to judge the soundproofing abilities is through their STC or Sound Transmission Class. MLV is unique because its STC is high and has lower mass and volume than other products. As you can see, Mass Loaded Vinyls are the ideal solution when it comes to soundproofing any part of the interior of your home. Most importantly, they can be installed around pipes and vents, taking noise dampening to a different level. Probably the only con is the price. MLVs are expensive, and that is why they can be a little hard to afford. But, due to its superiority compared to the other options currently available in the market, this investment is excellent.
Now, different companies manufacture MLV, which might confuse the buyer to choose such a wide array of options. Currently, Second Skin and Soundsulate are the leading names in the soundproofing industry.
Mass Loaded Vinyl (MLV) applications
Mass is a critical component in sound control and works by simply stopping sound from vibrating through its structure. Mass Loaded Vinyl (MLV) is an effective material to use in lining soundproofing curtains or blankets.
At even just ½LB per sq ft, MLV can produce a 25 STC rating, which is 1/16” thickness. You can get up to 35 STC by using 2lb per sq ft and 1/4” thickness; however, this is slightly more difficult to work with.
Effortless Installation and Broad Applications
Both Second Skin MLV123 and Soundsulate MLV4 are engineered for user-friendly installation, catering to DIY enthusiasts and professionals alike. Second Skin’s MLV variants, with their flexible and odorless nature, can be easily cut to fit and installed in vehicles, homes, and studios using glue or double-sided tape. This adaptability extends to Soundsulate MLV4, which, thanks to its flexibility and non-toxic properties, is perfect for enhancing the acoustic environment of residential and commercial spaces.
The diverse applications of these MLVs, from dampening road noise in automobiles to insulating studios against airborne sound, underscore their versatility. Second Skin’s high temperature resistance makes it particularly suitable for environments subject to fluctuating temperatures, while Soundsulate’s impressive tear strength and wide temperature range ensure durability in a variety of settings.
