Composition and manufacture

The VITRAL® system comprises stainless-steel or aluminium glazed panels which are prefabricated to suit the shape and size of each project. When panels are to open, no additional casements are required, so the ultra-slim framing is retained, with sight-lines as little as 25mm. Opening units become almost invisible, closing flush with the rest of the system. Opening devices include simple manual operators, 24 or 230V linear or chain actuators and pneumatic solutions.

A range of environmental-control safety glazing can be integrated into single- or double-glazed panels, as can solid, insulated materials. A choice of finish is offered from brushed steel or a selection of colours.


The stainless-steel system, VITRAL Inspiration, delivers market-leading thermal performance, achieving a very efficient overall U value of around 1.5W/m2K. It is compliant with Part L specifications for air permeability. All watertightness requirements are exceeded. Integral natural vents can be top or bottom hung, and the control options allow manual or automatic comfort venting, cold smoke clearance and full, life-safety, fail-safe smoke evacuation. Panels and associated controls have been independently tested as natural smoke and heat-exhaust ventilators (SHEVs) to BS EN 12101-2.


Prefabrication ensures fast, safe installation, minimal breakage risk and excellent quality control. A network of Trained Approved Specialist Contractors (TASC) provides full coverage of the UK.


The VITRAL® system provides natural daylight and natural ventilation, which reduces energy consumption and therefore reduces damage to the environment.
