Cavity Barriers
Silverliner® OSCB Horizontal Cavity Barrier
Silverliner® Open State Cavity Barrier (OSCB) is developed to protect the voids between the outer façade and the inner construction element of the building. The product is designed for use in a ventilated façade, the Silverliner® OSCB allows for 25mm or 50mm linear air gap to ensure movement of air and drain any moisture within the facade. The aluminium foil restricts fibre migration and offers a class ‘0’ rating. In the event of a fire the intumescent outer edge of the product will expand and close the ventilation gap between the product and the façade preventing the passage of fire and smoke from one compartment to another.
Intended areas of Use:
• Between the inner substrate and the external building envelope
• In conjunction with Paraflam® where vertical Cavity Barriers are required
• Where movement of air and moisture is required
• Systems to cover void ranges from 2mm - 550mm

The FSi Silverliner® Open State Cavity Barrier (OSCB) range has been tested in accordance with ASFP TGD19:
“Open State” Cavity Barrier used in External Envelope or Fabric of Buildings.
This test method specifies a procedure for determining the fire resistance of ‘open state’ cavity barriers when
subjected to the standard fire exposure conditions and performance criteria stipulated in EN 1363- 1 This
method is applicable to non-loadbearing, horizontally oriented ‘open-state’ cavity barriers, which are used to
provide fire separation within cavity voids such as those located between an external envelope and the face of
a building. The tests have been undertaken to assess the ability of the Silverliner® OSCB systems to reinstate
the fire resistance rigid/aerated concrete supporting construction. -
