Knauf Insulation launches ‘gateway-ready’ rainscreen cavity systems
K nauf Insulation has Rocksilk® launched
RainScreen Cavity Systems, a range of complete tested systems designed to simplify specifi cation and support compliance in cladding and masonry facades. The systems consist of sheathing insulation, fi xings, and cavity barriers. “The Building Safety Act places much more scrutiny on everyone working on high-risk buildings,” said Luke Davies, Rock Mineral Wool product manager at Knauf Insulation. “The ‘gateways’ it introduces, plus the ever- stricter compliance criteria of the Building Regulations, mean it’s never been more important to get your specifi cation right. That’s why we’ve launched these systems – to make it easier for specifi ers to meet these challenging requirements with a single system, backed up by rigorous test data.” The Rocksilk®
RainScreen Cavity Systems
combine existing Knauf Insulation rainscreen products with a series of new cavity barrier solutions, including open state cavity barriers with an intumescent strip, a closed state cavity barrier, and further additions to Knauf Insulation’s innovative face-fi xed masonry cavity barrier range launched last year. The full range of cavity barriers enables specifi ers to choose the system that best meets their fi re performance needs, confi dent it has been tested to the relevant standards. Rocksilk® RainScreen Cavity Systems can be used with the major substrate types, including blockwork, steel, and timber. The full range of cavity barriers consists of: Rocksilk®

Rocksilk®
RainScreen OSCB and
OSCB Plus are horizontal cavity barriers manufactured from rock mineral wool, shrink wrapped with a reactive intumescent strip, for use in ventilated cavities up to 450 mm. Rocksilk®
RainScreen FFCB is a patented cavity barrier made from rock mineral wool, that is designed to be face-fi xed to Rocksilk®
RainScreen Slab as the masonry
facade is constructed. It is non-combustible with the best possible Euroclass A1 reaction to fi re classifi cation and is manufactured using our unique bio-based binder, ECOSE® Technology. It is the only cavity barrier that can be fi xed to the face of the sheathing insulation without needing to cut into it, which reduces waste, saves time and protects performance.
Each cavity barrier has been tested as part of a system with Rocksilk®
RainScreen Slab
sheathing insulation to provide fi re resistance in the appropriate rainscreen facade applications.
