Silverliner® Open State Cavity Barrier
Verified by manufacturer 6 months ago
Open state cavity barrier.
Application
Application and 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 2–550 mm.
Description
Silverliner® Open State Cavity Barrier (OSCB) systems have been 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, with a 25 mm or 50 mm linear air gap to allow the movement of air and drainage of 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 facade preventing the passage of fire and smoke from one compartment to another.
Features and benefits:
- Third party approved - IFCC - IFCC 1672
- Non-combustible core.
- ‘Dry fit’ solution, no cure time.
- Fast installation using brackets .

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. |
