New ROCKWOOL® Solution Simplifies Rainscreen Fire Stopping

04/08/2021

Responding to the market’s need for simplified specification of fire stopping solutions in rainscreen systems, ROCKWOOL has streamlined its range of open state cavity barriers (SP Firestop OSCB) to provide a two-hour performance rating for both 25mm and 44mm open cavities.

Designed for use in conjunction with ROCKWOOL RAINSCREEN DUO SLAB®*, SP Firestop OSCB is fully tested to ASFP TGD-19 and is proven to provide up to 120 minutes fire integrity and insulation. ROCKWOOL SP Firestop OSCB is now available for cavity widths up to 600mm, inclusive of a 25mm open air space (OSCB 25), or cavities up to 425mm with a 44mm air space (OSCB 44).
