Silverliner® OSCB Horizontal Cavity Barrier

Briklok system has been tested to TGD-019 in conjunction with cavity barrier system FSi Silverliner OSCB1 Horizontal Ventilated Cavity Barriers rated E90 I30, achieved a combined rating of E90 I30, unaffecting the performance of the 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, typically used in horizontal applications at floor junctions and around window openings.

The Silverliner® OSCB allows for 25mm or 50mm linear air gap to ensure movement of air and drain any moisture within the façade.

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.

The Product comes in four different versions, achieving different air gaps and fire performance as follows:- 

• OSBC 1 - 25mm Air Gap, (E) Integrity 90 / (I) Insulation 30
• OSBC 2 - 50mm Air Gap, (E) Integrity 60 / (I) Insulation 30
• OSBC 3 - 25mm Air Gap, (E) Integrity 120 / (I) Insulation 120
• OSBC 4 - 50mm Air Gap, (E) Integrity 90 / (I) Insulation 60 (Void Size 54 - 354mm)
• OSBC 4 - 50mm Air Gap, (E) Integrity 60 / (I) Insulation 60 (Void Size 355 - 550mm)
