Visual consistency
  • Unique aluminium structure for all external appearances. The discreet and consistent 52 mm for the mullions and transoms give a uniform appearance to the entire GEODE range.

Concealed opening vents
  • These opening frame solutions provide natural ventilation whilst maintaining the aesthetic lines whatever the appearance of the external façade.

Thermal efficiency

The structure’s integrated thermal break and the possibility of using the highest performance glazing means that the lowest Ucw coefficients can be achieved. Energy consumption for heating, lighting, ventilation and air-conditioning is reduced.

Variety in the appearance of the façade

The range of mullion-transoms and external caps makes it possible to vary the appearance of the façade.

Increased resistance to climatic conditions

Fully injectable, the mullion/transom assembly spigot ensures the precise and controlled injection of sealant to ensure weather tightness. A secondary mullion drainage system enhances weather performance and quality. The system is zone drained and pressure equalized to ensure optimum performance and effective drainage in the most demanding environments.


GEODE is a comprehensive curtain walling suite offering designers high thermal performance to meet even the most stringent building regulations, and a wide range of aesthetic options based on a single system.

The variety of curtain walling applications, uses the same mullion and transom grid, and enables designers to vary the external appearance of the building envelope whilst benefitting from the design and construction options of a fully integrated system.

The GEODE range offers all the inherent qualities of aluminium: aesthetics, durability and low maintenance, and combines innovative technology and construction features with advanced manufacturing techniques for quality installation and long-lasting performance. This system is the result of Technal’s ongoing development program and has been rigorously tested in accordance with European standards for wind resistance, water tightness, and air permeability.
