EJOT CROSSFIX raises the bar on rainscreen facade performance


E JOT’s all-stainless steel facade


substructure system CROSSFIX can play an instrumental role in the delivery of higher performing, more sustainable and stronger rear ventilated or rainscreen facades. This complete framing


system, backed


with a comprehensive European Technical Assessment (ETA) to independently confi rm its performance, is compatible with all types of building substrates, insulation materials and cladding. It is supplied as a package by EJOT UK including all the brackets, rails, anchors and fasteners, plus the ‘Powerkey’ to optimise load distribution between anchors, required to assemble a robust sub-frame that achieves signifi cantly higher load-bearing capacities than other substructures.


Discover CROSSFIX at Zak World of Facades


Attendees at the Zak World of Facades event in Manchester in June will be able to fi nd out more about the contribution that CROSSFIX can make to facade projects. The EJOT UK team will be exhibiting to give architects and facade designers the opportunity to discuss the technical characteristics of the system and its design features in depth.


Reduced thermal bridging + greater strength = less material use One of the major advantages offered by CROSSFIX is its stainless steel composition, which offers low thermal conductivity compared to aluminium. As each bracket in the substructure provides the potential for a thermal bridge to develop, by reducing the amount of thermal transfer through the brackets, heat loss can be cut.


Stainless steel brackets have an additional advantage


given the systems, material’s fewer brackets substructure systems. relatively


higher strength. This means, compared to facade substructures created using standard aluminium


are


required with CROSSFIX – and with fewer structural connections from the building substrate to the outer sheet, a further reduction in thermal bridging is achieved. These thermal effi ciencies can enable a reduced insulation depth without compromising


Uvalues, decreasing the wall thickness,


potentially increasing


usable fl oor space and reducing insulation volumes. Combined with stainless steel’s recyclability and verifi ed EPDs supporting BREEAM, LEED and Passivhaus, this makes CROSSFIX well suited to projects with more ambitious sustainability targets.


Designed for both vertical and horizontal systems The design of the CROSSFIX Konsole bracket means it can be used with both vertical and horizontal rails,


offering greater design


fl exibility and allowing rail orientation to suit cladding formats and joint alignment. Its dual capability simplifi es adaptation to complex geometries, facade setbacks and mixed cladding systems, and it is especially valuable where materials change late in the design process. It also enables designers to select the most effi cient load path without redesigning layouts or switching


In addition,


CROSSFIX provides generous tolerance compensation for uneven substrates, making alignment easier on site, reducing shimming and rework and delivering cleaner facade lines with faster installation.


First rate fi re performance Being manufactured


from stainless steel,


CROSSFIX is well suited to modern fi re safety requirements. The material maintains good strength at high temperatures, retaining around 55% of its strength at 700°C. As a result, the system achieves an A1 fi re rating under EN 135011, making it a robust, noncombustible alternative to aluminium or hybrid substructures.
