Nordic Copper Inside and Out A

strong, decorative approach to copper cladding for both internal and external surfaces – combining three

different Nordic Copper products from Aurubis – defines Onslow House, a prominent commercial headquarters building in the heart of Guildford. Interior design and external alterations, designed by architects AWW, sought to add value to letting space and bring the 90,600 ft2 building up to date. The updated, massive, glazed entrance atrium incorporates feature walls – including inset doors – faced with horizontal copper panels, alternating in three different surfaces: Nordic Standard bright ‘mill finish’, Nordic Brown Light and Nordic Brown pre-oxidised copper. The Nordic Brown range offers lighter or darker colour shades determined by the thickness of oxide layer. Structural columns are similarly enwrapped

with alternating finish copper bands and the copper detailing is even continued into elements of bespoke furniture. The internal copper cladding had a post-lacquer finish applied to arrest further oxidisation, so

retaining the three colours and protecting the surface. This creates a reflective surface, mirroring and enhancing the lightness of the atrium space. The same horizontal copper panel composition of three surfaces continues past the external glazing to the outside. Here, the building’s entrance has been transformed with new copper-clad canopies to create a strong, easily recognised identity, with minimal work to the existing building envelope.

Externally, the copper has not received a

lacquer finish, as AWW explain: “We consider copper’s natural surface development outside, reflecting the local environment, to be one of the material’s key attributes. An attractive, gradual weathering and softening of the differentiation between the three Nordic Copper surfaces on the canopies has already begun – and will continue over time – as we anticipated.” Fabrication and installation of the Nordic Copper panels was carried out by specialists CGL Facades. In addition to Nordic Standard and Nordic

Brown, extensive Nordic Green, Nordic Blue and Nordic Turquoise ranges have been

developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world. A wide choice of Nordic Decor mechanically applied surface treatments is also available. Nordic Copper alloys include Nordic Brass

– which can also be supplied pre-weathered – and Nordic Bronze, an alloy of copper and tin initially with a similar colour to Nordic Standard, which gradually changes to a stable, dark chocolate brown. The innovative Nordic Royal, an alloy of copper with aluminium and zinc, enjoys a rich golden through-colour which remains very stable.

Profile 22 Flush Tilt & Turn Windows were chosen for a £24 million project to build new accommodation for 735 students at Sheffield Hallam University. While aluminium windows were specified for the building’s street facing elevations

in order to meet planning requirements, Profile 22’s high performance Flush Tilt & Turn Windows in Smooth Anthracite Grey were specified for the internal courtyard. Purposely designed for medium and high rise buildings, the sash on the Flush Tilt & Turn Window is neatly positioned inside the frame of the window to create an elegant and sleek ‘flush’ appearance that means it is a cost-effective alternative to aluminium.
