There is more to architectural copper than meets the eye, particularly in terms of recyclability, sustainability and long-term performance with an unrivalled lifespan and no maintenance. And, with a melting point of 1083˚C and ‘A1 (non-combustible material)’ fire classification to EN 13501-1, copper is suitable for cladding tall buildings, using appropriate constructions.
Copper’s unique visual qualities are defined by its natural patina, developing gradually in the environment – which cannot be replicated successfully using other materials with surface coatings – but the Nordic Copper range provides all these surfaces straightaway. The processes involved are generally similar to those taking place over time in the environment, utilising copper mineral compounds, not alien chemical processes. All these surfaces form an integral part of the copper, generally continuing to change over time in the environment, and are not lifeless coatings or paint.
The range includes Nordic Standard ‘mill finish’ and Nordic Brown pre-oxidised copper offering lighter or darker shades of brown determined by the thickness of the oxide layer. The extensive Nordic Blue, Nordic Green 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. As well as the solid patina colours, ‘Living’ surfaces are available for each with other intensities of patina flecks revealing some of the dark oxidised background material.
Copper alloys include Nordic Bronze and Nordic Brass, which can also be supplied pre-weathered. And the innovative Nordic Royal is an alloy of copper with aluminium and zinc, retaining its golden colour.
Copper is also the metal of choice for interior design, being non-toxic and with inherent antimicrobial qualities making it ideal for touch surfaces. Nordic Décor takes interior design opportunities with copper to a new level, with eight embossings for rich surface textures and seven grindings for distinctive matt surfaces – each with its own warm natural colour tone. Nordic Décor products are well-suited to a wide range of internal applications, such as wall and ceiling cladding – including elevators – highlight surfaces, bars and counters, as well as external facades. The material can be shaped, edged, milled, lasered, cut and bent.
Nordic Décor Embossings are available in Nordic Brass Weathered or Nordic Royal alloys, Nordic Brown and Nordic Brown Light pre-oxidised copper, and Nordic Green pre-patinated copper. They provide regular patterns of raised or recessed forms, some abraded to reveal highlights of the base material colour for additional design effects. Nordic Décor Grindings are available in Nordic Brass Weathered or Nordic Brown. They are abraded with linear, cross-hatched or curved-swirl hairlines to give distinctive matt surfaces.
