ISOL SILSONIC BRT 401 is a sound-insulating panel made of two layers of 100% thermally bonded regenerated fiber, certified to meet the strictest hygiene requirements, with an interposed high-density flexible elastomeric barrier in class B s1 d0 to increase mass and improve sound insulation. The fiber layers are designed to decouple the heavy barrier from the noise source.
To provide additional resistance to high temperatures, one layer of regenerated fiber is coupled with glass fiber to be positioned towards the noise source.
This product is also available in an adhesive version with water-based acrylic glue.
Isol Silsonic BRT 401 is resistant to humidity.
Typical applications
Isol Silsonic BRT 401 is designed for applications requiring a sound-insulating material with thermal resistance. It is particularly suitable for the marine sector and for soundproofing of industrial machinery.
Other applications include: heavy transport equipment, earth-moving machines, acoustic enclosures, engine rooms, compressors, motors, fan rooms, machine casings, exhaust pipes, industrial refrigeration, and similar applications.
