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