RF50-FR Rainscreen Facades System

RF50-FR Rear Fixed Fire Rated Rainscreen System

RF50- FR is a hook-on, rainscreen cladding system using 50mm deep cassette panels that are overlapped horizontally to create a baffle joint. The vertical joint is created using a unique Spanwall extruded aluminium mullion that incorporates anti-vibration EPDM gaskets and optional infill strip. The mullion is mounted to the substrate wall using adjustable helping hand brackets. These helping hand brackets create the insulation/cavity zone and transfer the wind and dead loads to the wall. The RF50-FR cassette panels are retained by hooks which are attached to the extruded vertical mullion using an M8 bolts and self-locking nuts and secured with anti-lift screws. The Spanwall RF50-FR is a non-loadbearing drained and back ventilated rainscreen cladding system.

As with all Spanwall rainscreen panels systems, austenitic stainless steel fixing screws and bolts are used.

Testing & Certification

RF50-FR has been independently tested in a “through wall” system and carries BS8414-2:2020 Fire Performance Classification in accordance with BR135 (3rd edition): 2013 and is suitable for use on high rise buildings.

Spanwall chose the most rigorous test regime, assessing panels sizes much larger than the norm at the largest floor spans and deepest cladding zones practical, to prove that the RF50-FR fire rated rainscreen system is truly fit for whatever configuration you might specify.

RF50-FR is designated A2-s1,d0 to EN13501-1 (when PPC is applied to the aluminium substrate, A1 if anodized) and has passed the standard for systemised building envelope testing by CWCT. RF50-FR also carries the prestigious UL Mark – Performance of Curtain Walling and Rainscreen Cladding.

These independent test certificates and standard CAD drawings are available in downloads via the products tab. 

Spanwall offer a full range of ancillary products and solutions to complement the RF50-FR, these include a secondary support system, flashings, custom fabrications, FINS, welding, stud welding, routing, perforating, and profiling.
