Architecture giant Foster + Partners has teamed up with Danish supplier Velux to launch a range of openable and modular skylights which offers greater levels of insulation.
The product was unveiled at a event on 13 September at 30 St Mary Axe, Foster’s ‘Gherkin’ tower in London.
The range of three skylights is designed to function in a wide range of building types, from offices to schools, retail spaces and hotels.
It can be used to create a single window or long light, or even to cover an entire atrium.
Paul Kalkhoven, senior partner and head of technical development, Foster + Partners, said: “We were impressed by the VELUX approach, particularly their investment in research and development and the reliability that this brings.
“Our contribution to this collaboration was the refinement of the appearance, the integration into various roof configurations and setting the performance and sustainable design criteria, to meet the needs of architects, contractors and clients.”
The glazing is framed by slim profiles, which maximise daylight, offer high thermal performance and can integrate glare control blinds.
Strong, slim pultrusion profiles have a thermal performance comparable to timber, combined with a tensile strength greater than aluminium or steel – yet, compared to aluminium, the glass fibre composite is more sustainable and still strong enough to support triple-glazed units up to three metres long.
The roof light achieves a U-value of just under 1.0 W/m²K for the whole unit, including the frame.
Motorised controls can be linked to BMS systems to form part of a low-energy, whole building lighting, heating and ventilation approach.
The Velux Modular Skylights range is launching first in the UK, Denmark and Sweden in 2012, followed by Belgium, Holland, Germany and France in 2013.
