With structurally glazed façades currently very much in vogue, architects and specifiers are expected to welcome the arrival in the UK of VISS SG, a new thermally insulated system from steel specialist, Schueco Jansen, which delivers the stylish 'all-glass' appearance they are seeking.
The effect is achieved by means of a special toggle and channel system which holds the glazed unit in place mechanically, without the need for the traditional mullion/transom pressure plate and cover cap profiles. This means that from the outside, only the narrow silicone joints between adjoining units are visible.
Utilising the outstanding structural properties of steel, Schueco Jansen VISS SG façades are characterised by long spans and large glazed areas. With the system being capable of supporting glass panes up to 2.5 m wide x 5.0 m high and weighing up to 800 kg, VISS SG delivers maximum transparency for the building envelope together with excellent 'U' values.
The thermally insulated steel mullions and transoms of a VISS SG system can accommodate double- or triple-glazed units up to a thickness of 70 mm and readily fulfil the requirements of current and future proposed Building Regulations.
Based on Schueco Jansen's widely specified VISS range of steel façades, VISS SG is available in either 50 mm and 60 mm face widths and can be combined with any of the VISS profile family including VISS Basic, which can be mounted on any suitable support structure. This allows a wide range of options from a standard range of components.
