It is believed to be the world’s most sustainable office. Every aspect of Bloomberg, London, was conceived with
shared values of innovation, sustainability and well-being, according to its architect, Norman Foster + Partners.
The monumental 1.1m square feet building was designed with a 98.5% BREEAM rating, the highest design-stage score ever achieved by any major office development.
Occupying a landmark space between St Paul’s Cathedral and the Bank of England, the building spans an ancient Roman road. Behind its handsome sandstone exterior and bronze window fins are a number of products working hard to maintain the building’s sustainable ambitions and Outstanding BREEAM rating.
These products include Ravago Building Solutions’ Ravatherm XPS X thermal insulation, supplied to main contractor Sir Robert McAlpine by Radmat, whose divisional manager Gary Sutton says:
“The extensive range of XPS products and the versatility of their insulation materials made it ideally suited to this landmark project.”
A number of thicknesses were selected including 140mm Ravatherm XPS X 300 SL, 50mm Ravatherm XPS X 300 SB and 150mm Ravatherm XPS X 500 SB.
Ravatherm XPS X is a flame-retarded, XPS roof insulation product, which achieves significantly improved lambda
insulation performance and delivers a Global Warming Potential (GWP) of less than five. It has an A+ BRE Green Guide Rating for roofing applications.
The high compressive strength of Ravatherm XPS X insulation products make them suitable for high load bearing
applications. Their versatility can be attributed to their mechanical strength, high design load as well as resistance
to moisture and repeated freeze/thaw cycles. Ravatherm XPS X is blown with CO2 and also has a GWP of less than five.
The boards offer low thermal conductivity, easy and fast installation as well as a durable floor structure.
Richard Powell, Sales Manager, Ravago Building Solutions, says:
“Our XPS products allow architects to have greater creative flexibility because they provide exceptional thermal performance at lesser thicknesses. We’re delighted that these properties helped Bloomberg’s headquarters become one of the world’s most sustainable office buildings.”
