Curtain walling

Mechanical Structural Glazing


The Mxm structural glazing curtain walling is a technical design enabling the creation of fully glazed facades without attaching aluminium frames to the glazing. As an alternative to SSG (Structural Sealant Glazing), which uses traditional silicone sealant, the glazing for the fixed and opening sections is attached to the aluminium frame mechanically using special aluminium supports. From the outside, only the glazing and a thin gasket is visible.

Projects using curtain walling GEODE MX 52

UCLan Engineering Innovation Centre, Lancashire

United Kingdom
When architectural glazing specialist, Dortech, required a curtain walling system that could fit the performance and aesthetic requirements for the University of Central Lancashire’s (UCLan) Engineering Innovation Centre (EIC), Technal GEODE MX curtain walling system was specified.

Chelsea FC Training Academy Phase 1

United Kingdom

One of the most ambitious investments undertaken by a football club was predominantly glazed in high specification curtain walling. 

The architects design for the training academy at Cobham in Surrey provides an inspirational environment for players at every level, that successfully integrates into the greenbelt landscape. The campus style building features a curved roof, which helps it drop down to ground level at each end and has a natural living surface to help it to blend into the rural surroundings. 

GEODE MX Horizontal Trame curtain walling was specified for its horizontal emphasis to express the linear aspect of the building. The system was used on three elevations to give the academy an open and spacious feel, and an eye-catching, contemporary design. 

One the north and south elevations, the top mullions and pressure plates of the curtain walling were specially curved to follow the dramatic roof line. The system was finished in metallic silver, and glazed in clear, solar control glass with fritted panels to conceal the building's structure and services whilst maintaining a continuous glazed facade. Externally, the horizontal aerofoil caps to the curtain wall were silver, with contrasting black vertical profiles. 

The glazing is shielded from solar gain by a series of vertical brise soleil 'fins' that are clad in brass panels, which will weather naturally overtime.
