Polyester fiber sound-absorbing panel
SINTHERM FR Sound Control is a panel for acoustic corrections in interior environments, made from thermally bonded polyester fibers without chemical additives or water usage.
Applications
Thanks to its high performance and versatility, the product is suitable for various indoor acoustic climate control applications, allowing for different installation methods: baffles, islands, direct mounting, or integration into suspended ceilings.
Ideal for schools, theaters, gyms, restaurants, offices, open-plan spaces, and recording studios.
Advantages
The Sound of Silence - The sound-absorbing corridor
During the "The Sound of Silence" seminar, the sound-absorbing corridor made by Manifattura Maiano was inaugurated.
It is made of polyester panels, hypoallergenic, Oeko-Tex certified and therefore guaranteed non-toxic, and is already in use in many Italian schools with excellent results.
The corridor offers a solution to alleviate learning difficulties at school, sometimes also due to acoustic problems in classrooms.
