Foam sealant tapes and a thermal insulating and load bearing bracket support system from ISO Chemie were specified for what is said to be a world-first sustainable office retrofit, at Cambridge University.
The move sees Winframer units and Iso Bloco tape being installed at the University of Cambridge Institute for Sustainability Leadership (CISL) in an initiative to bring the property in line with current zero-carbon Passivhaus and BREEAM energy efficiency standards.
The 1930s built Entopia Building is being transformed into an ultra-low carbon sustainability hub designed to provide a new home for CISL as it brings together Cambridge’s academic and innovation communities with the university’s own network of companies to develop solutions to global sustainability challenges.
ISO Chemie is partnering with Internorm windows on a project that will see its Winframer prefabricated installation frames, which can accommodate cavities up to 250mm, fitted internally with 50 windows, enabling them to be supported independently from the face of the wall.
This is said to be the first-time that retrofitted windows are being installed as part of an office refurbishment to ensure compliance with some of the lowest emission standards in the world.
Impermeable to driving rain at a minimum of 1,000 Pa, Iso Bloco will provide a longer-lasting window seal and installation compliance to BS8313-4:2016. The tape offers an internal air-tight seal that has been tested at 1000 Pa pressure difference (20 times more than UK Building Regulations) and gives less than 0.1 m³ of air loss while offering a U-Value of 0.55 and sound reduction by 63 dB.
Iso-Connect Vario SD humidity regulating foil has also been specified for additional year-round high-performance sealing and improved UV resistance.
Andy Swift, ISO Chemie’s sales and operations manager – UK and ROI, said the products have been specified because they are Passivhaus certified and meet long term sustainability requirements.
He added: “this is the first time that we are aware of that an office retrofit rather than newbuild is being carried out to the lowest emission standards anywhere in the world.”
