Forteyo MLV is a high-density structural barrier built to block airborne noise and structural vibration at the source. Engineered to international acoustic standards, it delivers maximum mass with minimal thickness — securing absolute silence and privacy across luxury residences, commercial spaces, and high-performance studios.
TRIPLE-LAYER ISOLATION
Beyond absorption.
Total sound attenuation.
Total sound attenuation.
Unlike conventional acoustic foam that merely absorbs interior echo, Forteyo MLV is engineered inside structural walls to block sound transmission. Discover how three integrated layers systematically dismantle acoustic wave energy.
Gypsum / MDF
Initial Deflection. The rigid outer substrate acts as the first line of defense. It reflects high-frequency sound waves and reduces initial surface impact, but allows low-frequency vibrations to pass through.
Forteyo MLV
Massive Energy Drop. The core hero layer of structural isolation. Upon striking Forteyo MLV’s high-density visco-elastic structure, the vast majority of sound wave energy is instantly absorbed, converted into harmless thermal energy, and blocked.
Rockwool
Cavity Dissipation. The final acoustic trap inside the wall cavity. Heavy-density mineral fibers capture and dissipate any remaining air resonance, sealing the wall system for maximum sanctuary-level silence.
MATERIAL ENGINEERING

TECHNICAL CERTAINTY
Clear answers.
Before you build.
Everything you need to know about material durability, roll calculations, and installation support across Indonesia. Engineered clarity for seamless project execution.
How does Forteyo MLV withstand heat, moisture, and mold in tropical environments?
Engineered from high-density non-porous mass polymers, Forteyo MLV is inherently waterproof, mold-resistant, and non-degrading. It maintains structural density and acoustic integrity without rotting or emitting odors—even in high-humidity coastal climates like Bali.
Can Forteyo MLV be installed onto existing walls without major structural demolition?
Yes. Thanks to its ultra-slim profile (1.2 mm to 3.0 mm), Forteyo MLV can be direct-adhered or sandwiched onto existing masonry, drywall, or ceiling frameworks, providing maximum decibel attenuation with minimal loss of interior room dimensions.
Why use Forteyo MLV instead of standard acoustic foam or Rockwool alone?
Acoustic foam only dampens internal echoes, while Rockwool absorbs sound inside cavities. Forteyo MLV provides the dense physical mass required to actually block sound wave transmission through structural boundaries—delivering true isolation when combined in a multi-layer system.
Is Forteyo MLV fire-rated and safe for enclosed, air-conditioned luxury spaces?
Forteyo MLV is manufactured with flame-retardant additives and zero VOC emissions. It is completely odorless, non-toxic, and safe for sealed air-conditioned environments, meeting international building safety standards for luxury hospitality and residential projects.
How does Forteyo MLV handle stubborn low-frequency sub-bass where rigid drywall fails?
Rigid building materials suffer from a physics phenomenon known as the 'coincidence dip', where specific low frequencies pass right through. Forteyo MLV's limp mass property absorbs and dissipates vibrational energy before it excites the structure, successfully trapping sub-bass frequencies from home theaters, commercial venues, and mechanical equipment.
Will Forteyo MLV stop both airborne noise (voices, TV) and structural impact vibrations (footsteps, bass)?
Forteyo MLV excels at blocking airborne noise. For structural impact noise and footstep vibrations, it acts as a mechanical decoupling layer when sandwiched between building elements, breaking sound transmission bridges across floors and partition walls.
What surface finishes can be applied over Forteyo MLV assemblies?
Once Forteyo MLV is secured within the wall or ceiling assembly, it can be covered with standard gypsum boards, MDF panels, timber cladding, decorative wall panels, or wallpaper—leaving your interior design aesthetic completely uncompromised.
What level of decibel reduction (STC) can I realistically expect after installation?
Depending on your chosen variant (MLV Flex, Core, or Ultra) and overall wall assembly, Forteyo systems deliver direct Sound Transmission Class (STC) gains ranging from STC 20 up to STC 28 per layer, dramatically reducing perceived noise levels by up to 75% to 90%.
How do I calculate the required roll quantity or obtain an exact BOQ for my project?
Calculate your total wall/ceiling surface area in square meters and add a 10% allowance for seam overlaps and corner trimming. Alternatively, submit your architectural CAD drawings to our engineering team for an automated Bill of Quantities (BOQ) calculation.
Does Forteyo provide nationwide project consultation, installation supervision, and physical sample kits?
Yes. We provide nationwide supply across Bali, Jakarta, and all major Indonesian cities. Our acoustic engineering team offers technical consultation, onsite installation supervision, and physical sample kits for architect material approvals.
