Acoustic Foam | Acoustic PU Form Panels
Acoustic PU Form - Ecotone Systems
We provide superior quality high sound absorption polyurethane foam (PU Foam) / Acoustic PU form weakens the sound waves hitting it and minimizes the transmission of noise having an NRC (Noise Reduction Co-efficient) value of 0.8. These acoustic PU form panels are known for their fire retardancy and sound absorption characteristics.
These are widely used in hotels, ballrooms, recording rooms, clubs, architectural decoration, industrial workshops, etc. This foam can be easily glued to any other material such as non-woven fabric, gypsum sheet, sun mica, glass fiber.
Acoustic Foam is available in plain sheets, wedge and pyramid shape:-
- Plain sheet size -1000mm x 2000mm and 25 / 50 mm thick sheets.
