Rainscreen Introduction to the Generix Cladding System Generix has evolved following extensive research and development by Realstone and their partners within the stone facades marketplace. The Generix Cladding System has recently passed the CWCT test for ventilated rainscreen systems, at Taylor Woodrow’s test facility at Leighton Buzzard. The Generix system comprises of a series of façade tile options in different materials that can be selected by the designer and used in conjunction with a standard patented Techlever vertical aluminum rail and clip substructure. Developments are calling for fast track construction techniques to enhance performance with regard to build time and programme. Clients are demanding reduced build time and weather tightness as a necessity to ensure that the schemes can be let as soon as possible. Architects are choosing more and more varied façade treatments as an alternative to traditional products such as bricks and mortar which are more time consuming to install. As we are all aware, traditional bricks are predominately on the critical build path and ultimately slow the build programme down considerably. Specifiers are opting for façade treatments that can be installed quickly and with the minimum of on-site wet trades thus achieving ‘weather tightness’ sooner. This allows the internal fit out packages to be commenced earlier, ultimately resulting in an ‘on time’ completion. Specialist subcontractors often find themselves now being asked to take single source responsibility for many different façade treatments, this often involves being responsible for the installation of systems with many different support details and causes many design interface problems. Generix overcomes all of these problems for both the specifier and the specialist subcontractor and allows for generic detailing by the designer and ease of installation by the installer. Generix benefits from a single support system that is designed to carry several different façade treatments. The system may also be fixed floor to floor and facilitates movement. • The Generix substructure has been developed with the following remit: • High Strength – spanning capabilities • Low Weight – high quality extrusions • High Speed – ease of installation • Universal substructure arrangement – many façade types on one substructure • GENERIX is a ventilated rainscreen façade solution with the horizontal edges of the panels manufactured at 45°. This permits the use of an open horizontal joint that is more effective than a closed joint system for air and thermal movement; however, the system will still prevent excessive rain penetration even in strong winds • The panels are secured to the GENERIX vertical rail using the patented two piece stainless steel clip. To prevent vibration, the panels are compressed against a neoprene strip incorporated within the face of the GENERIX rail profile. The neoprene strip is concealed from view to prevent any degradation by ultra-violet light • The patented two-piece stainless steel clip that secures the panels to the vertical rail requires no drilling or mechanical fixing • The vertical GENERIX extruded aluminum profile transfers the dead load of the cladding back to the building structure and has an excellent resistance to any imposed wind load or forces. The system has been thoroughly tested and is capable of supporting loads far heavier than most panels specified. The profile has been designed to accommodate any thermal movement of the panels and to eliminate any possible problem due to the atmospheric corrosion or bimetallic reactions between clips and rails • GENERIX ventilated rainscreen façade system can accommodate the installation of building services such as drainage, electric and telecommunication services, water pipes, ventilators and flues without the need to incorporate bespoke access covers or plates on the visible façade • The GENERIX substructure is designed to allow the removal and re-installation of the original panel without damage by the use of a special GENERIX tool and clip. |
