Open state 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 25 mm or 50 mm 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.

Standard | To BS EN 1363-1.Guidance for specification option: 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. This is the standard assembly for testing such systems as performance of the barriers can then be classified. |
