Mass Loaded Vinyl Manufacturer in India: FAQ
What is SoundBlanket® Mass Loaded Vinyl (MLV)?
SoundBlanket® MLV is a high-density flexible noise barrier used for sound isolation in walls, ceilings and floors. It works as a dense barrier layer in multi-layer soundproofing assemblies.
Why choose MMTPL as a mass loaded vinyl manufacturer in India?
MMTPL supplies SoundBlanket® as a mass loaded vinyl manufacturer in India with B2B support: BOQ-ready sizes, project documentation, installation guidance and scalable supply for builders, architects and acoustic resellers.
What thickness should I choose – 2.5 mm, 4 mm or 6 mm?
• 2.5 mm – lightweight option for residential or small office partitions.
• 4 mm – balanced choice for professional projects such as hotels and home theatres.
• 6 mm – heavy-duty isolation for industrial or high isolation targets.
The correct selection depends on noise level, assembly design and performance target.
Can SoundBlanket® be used with mineral wool or polyester insulation?
Yes. MLV is commonly paired with Rockwool, Glasswool, or Polyester Fibre to combine absorption (insulation) and isolation (MLV) inside composite wall and ceiling systems.
How do I install MLV for best results?
Install as a continuous barrier with overlapped/sealed joints and airtight perimeter detailing. MLV can be mechanically fastened or sandwiched between boards; sealing gaps is critical to performance.
What STC rating does SoundBlanket® MLV achieve?
SoundBlanket® MLV is rated STC 30 at 2.5 mm and STC 34 at 4 mm, tested to ASTM E90. STC for the 6 mm grade is available on request. These are values for the membrane. The STC of a finished wall depends on the full assembly, including studs, boards, cavity insulation and how well joints and perimeters are sealed.
Do you offer custom thickness, white label or OEM supply?
Yes. Alongside the standard 2.5 mm, 4 mm and 6 mm grades, SoundBlanket is manufactured in custom thicknesses from 1 mm to 10 mm, with project-specific roll lengths, widths and densities. White label and OEM production is available for international customers, including private-label branding and buyer-specified formulations.
