PENTAFLEX® STK sound insulating cage is a two-part joint cage element made of galvanised structural steel and hydrophobic foam sheet. It acoustically decouples the wall. The integral stirrups guide the sound-insulation joint tape, stop it from drooping during casting and so guarantee that the cavity joint is reliably sealed. The PENTAFLEX® sound-insulation joint system is predominantly used in terraced or semi-detached houses. It can be used either in element wall constructions or for in-situ concrete construction. The PENTAFLEX® sound-insulation joint tape seals the building joint against pressurised and unpressurised water.
