A 3 mm × 1,800 kg/m³ black MLV roll — bends and drapes fully around any surface. Smooth face stays visible, base fastens directly onto drywall or ceiling before covering.
— OVERVIEW —
Yamamah Smart MLV is the ideal choice for residential, commercial and industrial projects throughout Saudi Arabia. With STC of 33 dB at just 3 mm thickness, it delivers exceptional soundproofing performance.
The heavier and denser the barrier, the more effectively it blocks sound — 1,800 kg/m³ density delivers exceptional performance.
Flexible material conforms to walls, ceilings, floors and irregular surfaces with ease.
Combined with drywall and rockwool, MLV reaches STC 50–60 dB total isolation.
— KEY FEATURES —
High-density barrier effectively blocks airborne noise and reduces sound transmission between rooms.
Excellent noise reduction across low, mid and high frequencies for comprehensive sound isolation.
Minimum thickness with maximum acoustic performance — preserves valuable floor and wall space.
Reduces structural vibrations and impact noise transmission through building elements.
Can be covered with drywall, hardwood, carpet, tile or cement finishes.
Works effectively from -20°C to +80°C — suitable for Saudi Arabia's climate.

— FREQUENTLY ASKED —
A thin, flexible, high-density soundproofing material made from PVC loaded with heavy fillers — weighing 4.8 kg/m² with density of 1,800 kg/m³, designed to add mass to walls, ceilings and floors to block airborne sound.
Standalone STC rating of 33 dB. Combined with standard wall assemblies (drywall + insulation), it achieves 50-60 dB STC — sufficient to block normal speech, TV and household noise.
Yes — MLV is excellent for floor insulation under carpet, hardwood, laminate and tile. It significantly reduces both airborne noise and impact noise between floors.
Yes. Class B fire rating (B-s1, d0) with very low smoke production, antimicrobial and waterproof — safe for hospitals, schools and food service areas.
No. The material is chemically stable and resistant to moisture, insects and mold — maintains performance for decades without maintenance.
Mass Loaded Vinyl is a viscoelastic composite: a flexible PVC (polyvinyl chloride) matrix loaded with dense mineral fillers such as calcium carbonate or barium sulfate to reach 1,800 kg/m³. The technology has been used in industrial sound control since the 1960s. Yamamah supplies the modern generation — with tighter density tolerances, low-VOC formulations, and Class B fire performance.
MLV works through mass and internal damping (hysteresis). Its high density reflects most airborne sound waves back to the source, while the viscoelastic nature causes the remaining vibration energy to dissipate as tiny amounts of heat inside the material itself. This dual mechanism — reflect + dampen — gives MLV a much broader frequency response than simple rigid barriers of the same weight.
No — direct-bonding MLV to a rigid wall or partition cripples its performance. The MLV needs a small degree of independent vibration to convert sound energy into internal damping. Bond it directly and you lose most of the STC gain plus you risk mechanical damage over time. Yamamah always installs MLV as a decoupled layer: either hung freely, sandwiched between two layers of drywall, or clipped on resilient channels.
Orientation itself has no measurable acoustic effect. What matters is minimizing joints and sealing them fully. Every unsealed seam is a direct sound leak, so we plan the roll layout to reduce the total joint length and always tape or overlap seams with acoustic sealant. On tall walls we prefer vertical drops (fewer horizontal seams); on ceilings we align rolls parallel to the shortest span.
For low-frequency sound (bass, HVAC rumble, traffic), yes — more mass = better attenuation. But at mid and high frequencies you gain much less per extra kilogram, and heavier sheets are harder to install and load ceilings more. Density and mass matter more than raw thickness: a 3 mm sheet at 1,800 kg/m³ (5.4 kg/m²) will out-perform a 5 mm sheet at 1,200 kg/m³ (6 kg/m²) at low frequencies despite similar total mass. Yamamah's 3 mm × 1,800 kg/m³ is the industry-standard sweet spot for STC 33.
Yes — MLV is one of the best solutions for noisy plumbing risers and HVAC ductwork. The flexible sheet wraps directly around the pipe, blocking the airborne and low-frequency structure-borne noise that hard insulation cannot handle. For pipes we recommend the aluminium-foil-backed variant: the foil adds a vapour barrier, resists moisture, and improves handling. Yamamah supplies foil-backed MLV in matching 3 mm density.
