FSPG Open State Cavity Barrier Non-Ventilated

FSPG Non-Ventilated Rainscreen Cavity Barrier is developed to protect the voids between the outer Rainscreen cladding / facade and the inner construction element of the building. It closes the void at installation, but allows for movement of the building components, depending on the building requirements. The aluminium foil facing provides class ‘O’ rating and excellent resistance to smoke.
