Merfoplex
The Isomat KE core reduces airborne noise and is fire-retardant
Processable with standard woodworking tools
Ideal for walls, floors, and doors
Merfoplex is a sandwich panel composed of two outer layers of Okoumé or poplar plywood with a visco-elastic mass core (Isomat KE). By combining the mass of the core with the stiffness of the wooden outer layers, Merfoplex provides excellent sound insulation while remaining workable with standard woodworking tools such as saws, drills, and screws. The layers are pressure-laminated, resulting in a stable panel that resists delamination and deformation over time. Because the outer layers are made of plywood, Merfoplex can be seamlessly integrated into furniture, interior finishes, floors, or wall constructions, combining a structural finish with acoustic performance.
Depending on the variant, panels are available in thicknesses of 16 mm (Okoumé + Isomat core), 22 mm, or 24 mm (poplar layers + core). Colour and finish depend on the selected wood species.
Merfoplex offers high sound insulation performance, tested according to DIN 52210. Sound measurements across different frequencies show significant reduction of airborne sound transmission in the mid- to high-frequency ranges. The visco-elastic core (Isomat KE) is fire-retardant (DIN 4102 B2), and the panel is resistant to water, oil, fuels, and many common solvents and cleaning products. The material remains stable up to approximately 80 °C and can be sawed, drilled, and mounted with standard woodworking tools, while providing enhanced acoustic performance.
Merfoplex is ideal for sound-insulating walls, floors, doors, and partitions. Typical applications include yacht and ship interiors, renovation projects, floors of buses or trams, soundproof doors, and any environment where a rigid wooden finish combined with sound insulation is required.

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.
