Bringing in the light with Kalwall

Bringing in the light with the Kalwall translucent daylight building system

Designed by DarntonB3 architects, this 23,000 sqm facility is the new HQ for Airedale International Air Conditioning in Leeds. The production facility is a stunning example of the way in which the Kalwall® translucent daylighting system has been used in combination with Kalwall panel unit windows. It includes a state-of-the-art test centre and training school regarded as a worldwide hub of excellence for air-conditioning.


The dramatic linear simplicity of the design projects real impact on the entrance façade while the architects have configured the levels of the site so that the main mass is concealed from public view and all aspects of manufacturing are kept on a single level. Sustainability is also fundamental to Airedale’s core strategy which has been translated into a BREEAM rating of ‘Very Good’ for the building.


Keith Hardcastle, Director at DarntonB3 architecture comments, “The ambiance within the factory has been transformed by the integration of natural diffused light into the usually harsh environment.”


Unlike conventional glazing, highly insulating Kalwall eliminates shadows and glare and the stark contrasts of light and shade. The system also enhances simplicity by eliminating the need for blinds, curtains or solar control. Even on cloudy days, the building is bathed with natural diffused daylight which means less artificial lighting and therefore reduced costs.
Apart from being specified for all types of new build, Kalwall is increasingly used for the refurbishment of cladding or rooflights on aged buildings.
