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.
It is hypoallergenic and free of harmful substances. The product resists moisture and is unaffected by microorganisms, mold, and insects. Easy to install and simple to cut, it does not release dust and is safe for skin contact. Flame-retardant, fully recyclable, and reusable, it is proudly manufactured in Italy at Manifattura Maiano's plant in Campi Bisenzio (FI).
Applications
Thanks to its high performance and versatility, the product is suitable for various types of acoustic climate control interventions in indoor environments, allowing for different installation methods and decorative solutions.
Ideal for schools, theaters, gyms, restaurants, and recording studios, with numerous application possibilities on walls, ceilings, and suspended ceilings:
- as baffles
- as island
- direct adhesion
- in suspended ceilings
Advantages
- Excellent sound-absorbing properties
- Compliant with CAM (Environmental Minimum Criteria for furnishings)
- Recycled and reusable at the end of its life
- Hydro-repellent and rot-proof
- Hypoallergenic
- Durable over time
- Easy to install, no PPE required
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.
