The secondary reinforced sound insulation joint formwork element for floor/ceiling slabs. The integrated joint insert made of sound insulating mineral wool serves for the acoustic separation of the component.
The formwork element is prefabricated in component thickness - taking the concrete cover into account.
The formwork element comprises a rubber water bar cage for watertight joints according to the dimension of the on-site rubber water bar.
The reinforcement and concreting work can be performed at the same time on both sides of the formwork element.
