Advantages
• Very high sound absorption, including improved low-frequency performance
• Advanced acoustic performance (higher than the 5 cm version)
• Significant reverberation reduction in large spaces
• Exceptionally lightweight material
• High fire resistance (flame-retardant)
• Does not crumble or shed fibres
• Resistant to high temperatures
• Grey shade – blends naturally into the design
Why this product
The 7 cm thickness is intended for situations that call for a more significant acoustic improvement, especially in large spaces or rooms with a severe reverberation problem.
It also delivers better performance at low frequencies than thinner versions.
Technical description
An acoustic panel made of melamine foam with an open-cell structure, providing exceptionally high sound absorption and reducing reverberation in rooms.
The increased thickness absorbs sound waves more efficiently, including lower frequencies, and significantly improves the acoustic quality of the space.
The material is lightweight, fire-resistant and does not release fibres, making it suitable for professional and architectural applications.
Applications
• Studios and recording rooms
• Large halls
• Commercial spaces
• Open-plan offices
• Meeting rooms
• Public buildings
• Spaces with severe reverberation problems
