![]() ![]() 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: Call us today to experience the quality offered by BS Stainless - your partner for stainless steel.Final Thoughts What is Mass Loaded Vinyl (MLV) Used For? Used in Soundmet® - mass loaded vinyl is securely bonded to a range of metal jackets to produce this innovative material, which offers significant cost- and labour-saving opportunitiesīS Stainless continue to supply mass loaded vinyl to many high-profile projects around the world, along with ancillary products such as stainless steel jacketing, springs, banding and wing seals. Strongly resistant to weak acids & alkalis, grease and mineral oilĪvailable in a wide range of sizes and with glass reinforcement, low-temperature and enhanced fire-resistant optionsĮasy to apply in difficult areas such as valve boxes and elbows when supplied with optional peel-off adhesive backing Used by several world-class companies such as Shellĭesigned with a high mass to optimise effectiveness when used for metal jacketing and acoustic pipe wrap application in the oil and gas industries Loaded with barium sulphate in accordance with ISO 15665 Mass loaded vinyl sound barriers from BS Stainless are:įabricated from high-density, naturally-occurring materials The tennis ball represents sound and the sheet represents the soundproofing material - if the material is limp and flexible then, in accordance with Newton’s Three Laws of Motion, sound energy can be ‘bled off’, resulting in higher net losses of sound propagation as the material moves in three-dimensional space. If the sheet was secured to the ground, the ball would be able to bounce, resulting in vibration of the sheet. ![]() A tennis ball thrown at a sheet hanging on a line quickly loses its energy - this is transferred to the sheet which can move freely in three-dimensional space. BS Stainless are expert suppliers of this flexible sound barrier, which is particularly suited to stainless steel jacketing solutions within gas and oil processing plants.Ī good analogy to help understand how mass loaded vinyl achieves its high levels of sound insulation is that of the tennis ball and sheet. Mass loaded vinyl is designed to dampen sound as part of an insulation system, ensuring health and safety regulations regarding noise levels in the workplace are adhered to. ![]()
