SoundBlanket® Mass Loaded Vinyl - Noise Barrier
A high-density mass-loaded vinyl noise barrier which is essential for soundproofing in walls, ceilings and floors. SoundBlanket is produced by MMTPL in 2.5mm, 4mm, 6mm and other required thicknesses.
Roll Size:
Key Solution: Provides sound isolation for low to high frequencies.
Applications
Building Structures: Ideal for isolating sound between floors, walls, and ceilings in high-rise residential buildings, commercial offices, and hotels.
Partitions and Interiors: Enhances soundproofing in wooden, gypsum, and metal partitions commonly used in cineplexes, nightclubs, banquet halls, auditoriums, home theatres, recording studios, and co-working spaces.
Partitions and Interiors: Combination Insulation elevates sound insulation performance by effectively complementing other insulation materials such as rock wool, glass wool, polyester fibre, and acoustic foams.
Our specification sheet provides detailed information on available thicknesses, dimensions, and performance attributes, allowing you to make informed decisions for walls, floors, and ceilings across residential, commercial, and industrial spaces.
Frequently Asked Questions
1. What is SoundBlanket® Mass Loaded Vinyl (MLV)?
SoundBlanket® MLV is a high-density flexible noise barrier made from polymer-based compounds with added minerals for mass and durability. It blocks airborne sound transmission through walls, ceilings and floors while maintaining a slim profile.
2. What are the main applications of SoundBlanket® MLV?
It is used in homes, studios, offices, hotels, auditoriums, cinemas, machine rooms and industrial enclosures. Typical uses include stud walls, partitions, under-floor layers, ceiling drops, and composite wall systems with insulation.
3. How is SoundBlanket® installed?
SoundBlanket® MLV can be mechanically fastened, sandwiched between boards, or adhered using Turbo® SR Adhesive. The joints are overlapped or sealed with acoustic tape to maintain an airtight barrier. Always ensure continuous coverage for best results.
4. 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-STC applications.
Thicker membranes provide higher sound-blocking performance due to increased mass.
5. Can SoundBlanket® be used with rockwool or glasswool?
Yes. SoundBlanket® is often paired with Rockwool, Glasswool, or Polyester Fibre insulation to create a complete acoustic system — combining absorption (from insulation) and isolation (from MLV).
6. What certifications does SoundBlanket® MLV have?
It is tested as per ASTM C423, ASTM E90 and ASTM E84 (Class A Fire Rating). The product also complies with ISO 354 and STC testing standards to ensure proven sound-transmission loss values.
7. Can SoundBlanket® be customised?
Yes. MMT Acoustix provides customised roll lengths, widths and densities for large projects. Private-label and OEM production options are also available upon request.
8. What is SoundBlanket® made of?
It is composed of polymeric resin compounds filled with inert mineral materials to increase mass density (approx. 2100 kg/m³). The formulation is lead-free, non-toxic and safe for indoor environments.
9. What are the delivery times and availability?
Standard thicknesses (2.5 mm / 4 mm / 6 mm) are kept in stock at MMT Acoustix manufacturing units in India. Typical dispatch time is 2–5 working days for national orders and 7–10 days for export shipments.
10. How is SoundBlanket® different from acoustic foam?
Acoustic foam absorbs echo and reverberation inside a room, while SoundBlanket® MLV blocks noise transfer between rooms. For best results, both materials can be combined – foam for absorption and MLV for isolation.
