SP Firestop OSCB
by Rockwool Group
Designed for use only in conjunction with either ROCKWOOL RainScreen Duo Slab or NyRock Rainscreen 032, SP Firestop OSCB forms an open-state cavity fire barrier within a rainscreen cavity.
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 an 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, SP Firestop OSCB is suitable for cavity widths up to 600mm (OSCB 25) and 425mm (OSCB 44).
