Rockwool SP Fire Stop OSCB 60 / OSCB 120

The Rockwool SP Fire Stop OSCB  is designed to form an open state cavity barrier within a rainscreen system. Manufactured from an intumescent strip fixed to high-density non-combustible Rockwool insulation. This allows for ventilation and drainage under normal service conditions. In the unfortunate event of a fire, the intumescent strips will expand causing the cavity to close and the spread of fire and smoke stunted. The Rockwool SP60 fire stop OSCB Slab can offer up to 120 minutes of fire protection.

SP FIRESTOP OSCB

Consisting of an advanced intumescent strip fixed to high density non-combustible ROCKWOOL insulation, SP Firestop OSCB is designed to form an open-state cavity barrier within the building facade.

This allows the product to maintain ventilation and drainage of the cavity under normal service conditions, while in the event of a fire the intumescent strip will quickly expand outwards to seal off the cavity, preventing the passage of fire and smoke.

Exclusively designed and tested for use only in conjunction with ROCKWOOL RAINSCREEN DUO SLAB, SP Firestop OSCB forms an open-state cavity barrier within the building facade, which allows for ventilation and drainage of the cavity under service conditions.

The product comprises of a continuous intumescent strip fixed to the leading edge of a foil faced stone wool barrier, encapsulated by a weather-resistant polythene sleeve.

Fully tested to ASFP TGD 19, the combination of non-combustible insulation with effective intumescent, supports the construction of safe façade systems and aids the design of high-rise buildings over 18m in height.

Installed horizontally and designed to ensure an appropriate open air space is maintained, the SP Firestop OSCB is suitable for cavity widths up to 600mm (see under ‘Performance’ for full details).
