Composition and manufacture

The VITRAL® system comprises pre-glazed, stainless-steel or aluminium panel frames, which span freely between support members. When panels are to open, no additional casements are required, so the ultra-slim framing is retained, with sight-lines from as little as 25mm. Opening units become almost invisible, closing flush with the rest of the system. Various components are available for applications, including self-supporting ridge and hip assemblies. An extensive range of environmental control and safety glasses can be incorporated into single- or double-glazed panels, as can solid, insulated materials. Clients can choose from brushed stainless 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 fully 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 offer a range from manual and automatic comfort venting through to full, life-safety, fail-safe smoke evacuation. Panels and associated controls have been independently tested as natural smoke and heat-exhaust ventilators (SHEVs) in accordance with 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.
