Lamilux Passivhaus Glass Roof PR60 Energysave

PR60energysave Atriums installed at University of Leicester New Medical Building

DVS have recently completed the installation of 2x PR60energysave Passivhaus certified atrium rooflights (each 7 x 16 metres at just 3° inclination) at the UK's largest non-residential Passivhaus building - The University of Leicester New Medical Building (pictured above).

The world's first Passivhaus certified glazed roof system

As the world's first certified glazed roof, the PR60energysave sets the benchmark for energy efficiency standards for atrium glazing. Independently assessed by the Passivhaus Institute and awarded the highest efficiency rating, the phA Advanced Component classification.
