Name: Hipertec Wall Sound
Brand: Metecno Bausysteme GmbH

Sound-absorbing sandwich wall panel

Description

Sound-absorbing sandwich wall panel with a mineral-wool core and a perforated steel inner skin. The perforation significantly improves room acoustics. A dedicated fleece between the inner skin and the mineral-wool core acts as a patented dust-protection layer. Usable as a ceiling, partition wall or, in special cases, an exterior wall. Not recommended for heated or humid rooms.
