Slim acoustic insulation wall

The IW90 is a slim insulation wall (90mm) with excellent acoustic qualities (50dB). The IW90 is a double-layer system. You put the wall together yourself on the construction site using two GP22 panels with a 46mm cavity in between them. This anchorless cavity – which will need to be filled with mineral wool – prevents impact noises and guarantees sound insulation. The IW90 stands out because of its light, simple construction.

The IW 90 is frequently used in offices, healthcare institutions, educational premises and, of course, in residential premises!
