STIRLING PRIZE SHORTLISTED
Meanwhile , the Windermere Jetty Museum was recently shortlisted for the 2021 RIBA Stirling Prize , having already won an RIBA National Award and the RIBA North West Building of the Year Award . The museum is unified and defined by facades and oversailing roofs clad in Nordic Brown pre-oxidised copper , further developing naturally over time and responding to the unique lakeside context .
It is seen and approached from all sides , from land and water , and from a number of points of elevation . Roofs and walls therefore assume equally important status in the formal composition . Nordic Brown pre-oxidised copper is used as the determining material to give architectural consistency to these elements and to the museum buildings working together as a cohesive whole . The copper is folded and pinned with a regular pattern of brass fixings to give the elevations a unique texture , which is further reinforced by the patina gained by weathering over time .
EXCEPTIONAL PERFORMANCE NATURALLY
Nordic Brown is part of an extensive range of architectural copper surfaces and alloys with an unrivalled lifespan , no maintenance and full recyclability . With a melting point of 1083˚C and ‘ A1
AURUBIS
( non-combustible material )’ fire classification to EN 13501-1 , copper is suitable for cladding tall buildings , using appropriate constructions .
As well as Nordic Standard ‘ mill finish ’ copper , the extensive Nordic Copper range also includes Nordic Brown with the same oxidised brown surface that otherwise develops over time in the environment . The thickness of the oxide layer determines the colour of the surface finish , with darker or lighter ( Nordic Brown Light ) shades of brown .
LIVING COPPER SURFACES
Nordic Blue , Nordic Green and Nordic Turquoise pre-patinated surfaces have been developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world . As well as the solid patina colours , ‘ Living ’ surfaces are available for each colour with other intensities of patina flecks revealing some of the dark oxidised background material .
Copper alloys are growing in popularity as well , including Nordic Bronze and Nordic Brass – which can also be supplied preweathered . The innovative Nordic Royal is an alloy of copper with aluminium and zinc , giving it a rich golden through-colour and making it very stable .
