Copper Composite Material – Rainscreen Cladding

Blend the natural beauty of copper with the flatness and formability of composite panels

Featured Project

Sotech were engaged by BAM to produce over 1100 square meters (9700 individual parts) of Copper Shingles in the refurb of The NIA. Now renamed the Barclaycard Arena, this is one of the busiest, large scale indoor sporting and entertainment venues in Europe. Work on the £26m redevelopment of Birmingham’s National Indoor Arena (NIA) commenced in June 2013 with full backing by Birmingham City Council as part of their ‘Big City’ Plan.

The modernisation of the NIA took advantage of its unique location on the city’s canal side: the most dramatic element is the new glass-fronted façade offset by the Sotech’s striking copper shingles which created a dynamic arrival for visitors and adding 5,926 m² of pre/post show space into the 13,437 m² of the redevelopment. Iconic ‘Sky Needles’ on top of the NIA also added to the skyline of Birmingham and light up at night.

Provides design flexibility, as the material can be moulded into complex shapes

Lighter weight than heavy gauge copper.

Composites are less likely than metals (such as aluminium) to break up completely under stress.

CCM forms a natural green patina, transforming its bright natural finish to a distinguished, classic look.
