Insulation For Walls | Sound Insulation For Walls
Insulation for Walls
Mass loaded vinyl (MLV) is a safe non-toxic acoustic insulation for walls material designed for use as a soft mass suspension in a variety of sound insulation applications. MLV sound insulation is a low-cost alternative to lead sheeting noise insulation for walls. Our custom designed mass-loaded vinyl noise barriers are provided at a density of 4 kg/m2.
Sound Transmission Class
It’s an industry standard measuring unit for internal wall insulation materials, such as mass loaded vinyls for walls, ceilings or flooring components, is known as sound transmission class (STC). Standardized testing in certified independent soundproofing labs, measure transmission losses between noise source and target room. Measuring range from 125Hz to 4000Hz of six frequency points. The difference between the two rooms is transmission loss. Our quality sound deadening insulation for walls is STC 26, which ensure that you receive effective soundproofing for your home or office.
The soundproofing insulation for wall system combines mass, isolation, absorption and damping to achieve the most suitable application for sound reduction results. The MLV insulation for walls increases mass with minimal thickness. MLV is usually embedded behind solid soundproof panels, finished wall, floor or ceiling material.
