Robust acoustic insulation wall

The IW100 is a 100mm thick robust acoustic insulation wall (45dB). The IW100 is a double-layer system. You put the wall together yourself on the building site using two VP35 panels with a 30mm cavity in between them. This anchorless cavity – which will need to filled with mineral wool – prevents impact noise and guarantees sound insulation. The IW100 is a solid wall, perfect for guaranteeing privacy in board rooms, law firms, banks and in hotel rooms, for instance.

The IW is also eminently suitable for use in a residential, work, educational or care environment.
