Isomat KE
Reduces airborne and structure-borne noise
Used independently or in sandwich panels
Ideal for walls, floors, and partitions
Isomat KE is a visco-elastic mass panel designed for effective sound insulation of walls, floors, ceilings, doors, and partitions. Its visco-elastic core reduces both airborne and impact noise, making it suitable for construction, interior, and transport applications. Isomat KE retains its shape and dimensions and is resistant to moisture, oils, fuels, and standard cleaning products. It can be used as a standalone soundproofing layer or as the core of sandwich panels such as Merfoplex, combining structural stiffness with high acoustic performance.
The panel provides strong sound insulation performance, tested according to EN 140-3 and ISO 717 over a wide range of frequencies. The visco-elastic core is fire-retardant and certified according to DIN 4102 Class B2, ensuring safe use in buildings, vehicles and interior applications.
The panels are available in two versions:
- KE 8 (3 mm thick, 8 kg/m²)
- KE 14 (5.2 mm thick, 14 kg/m²)
The material has a high bulk density of 2,800 kg/m³. It absorbs vibration energy, reduces impact noise and maintains long-term acoustic and mechanical performance. At the same time, it remains easy to handle and install.
Isomat KE is suitable as a standalone soundproofing layer or as the core of sandwich panels. Typical applications include ship interiors, building renovations, vehicle floors, and high-end interior constructions requiring high levels of sound insulation. The combination of mass, visco-elasticity, and fire-retardant properties makes it ideal for environments where both acoustic performance and safety are essential.

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.
