Acusticell MMF
Weighted sound absorption coefficient up to αw = 0.80
Fire-resistant and thermally durable
Lightweight and durable panel design
Noise and heat in technical spaces can reduce comfort and safety. Acusticell MMF is a sound-absorbing panel that helps reduce sound, especially mid- and low-frequency noise. At the same time, it reflects heat and protects surfaces. The panel is made from open-cell polyurethane foam with a self-adhesive aluminium top layer. This layer is reinforced with glass fibre, making the panel strong and durable. It can be used on walls, ceilings and enclosures in machine rooms, engine compartments, vehicles, boats and generator rooms. The reflective aluminium surface also improves visibility in darker spaces, making inspection and maintenance easier. Compared to Acusticell VSP, this panel provides slightly better sound absorption in thicker versions.
Depending on how it is installed, Acusticell MMF offers sound absorption between αw = 0.40 and 0.80. The aluminium layer is self-adhesive and resistant to temperatures up to about 100 °C. It is also tested according to the FMVSS 302 safety standard. The panel is thin (10–15 mm) and lightweight (120–170 g/m²), making it easy to use while still being strong.
Because the aluminium layer is quite rigid, the panel should be installed on a flat surface. Seams need to be sealed carefully to prevent sound or moisture from getting through. The panel can also be combined with other acoustic materials, such as Merfodem® or Akoestifoam®, to further improve sound reduction and vibration damping.
Acusticell MMF is suitable for machine rooms, engine compartments, vehicles, boats and generator rooms where both sound reduction and heat reflection are important. Its lightweight and strong construction makes it ideal for spaces with limited room, high temperatures or heavy use. The panel reduces noise and protects surfaces from dust, oil and moisture.

Answers to common questions
Merford can perform acoustic analyses or simulations to predict noise levels and reverberation times based on material selection, room dimensions, and finishes, ensuring the right solution is designed.
Our acoustic materials generally require minimal maintenance. Dusting and cleaning is usually sufficient to maintain long‑term performance.
- Vibration isolation reduces mechanical vibrations from machines or equipment, preventing transmission to the building structure or floor.
- Sound insulation prevents sound from passing from one space to another, e.g., between rooms or to the exterior.
- Sound absorption reduces echo and reverberation within a space by damping sound waves, improving comfort and speech intelligibility.
Merford materials can provide one or more of these effects depending on the product type, such as absorption panels for rooms or isolation around ventilation units.
