Akotherm GG
Sound absorption up to αw = 0.80
Hypoallergenic, dust-free and flame-retardent
Smooth, double-sided aesthetic finish
Akotherm GG is a sound-absorbing panel that helps reduce echo (reverberation) and makes spaces quieter and more comfortable. The panel is made from recycled polyester wool and has a smooth surface on both sides. This gives it a clean and neat appearance, allowing it to be used visibly on walls and ceilings.
The material is safe to use: it is hypoallergenic, dust-free and contains no chemical binders. This makes it suitable for spaces where people spend a lot of time, such as offices, healthcare facilities and schools. The panels have a material density of approximately 40 kg/m³. This makes them strong, shape-stable and ensures long-term performance.
The standard panel size is 1,200 × 1,000 mm.
Akotherm GG absorbs sound with a value of αw = 0.60 to 0.80, depending on how it is applied. It mainly helps to reduce reverberation in spaces with hard surfaces. It also provides thermal insulation. Thermal insulation is tested according to DIN 52612, Type D20, with a thermal conductivity of λ = 0.040 W/(m·K). The material is lightweight, keeps its shape well and is fire rated according to EN 13501-1 Class B and DIN 4102 Class B1.
The panels are easy to cut to size and simple to install on walls or ceilings using standard adhesive.
Akotherm GG is suitable for spaces where both good acoustics and a visually appealing finish are important, such as offices, studios, shops and residential environments. Because of its smooth surface, the panels can be installed visibly without additional finishing. They can also be integrated into furniture or other interior elements to further improve comfort in a space.

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.
