We use copper products by two of the world’s leading manufacturers for our copper roofing works: KME and Aurubis.
KME’s TECU® range of copper, and copper-alloy, materials and systems offers a combination of high quality, durability, diversity and stunning aesthetics. TECU® can be used for the whole façade or roof, or to pick out feature areas and trims. Surfaces available include traditional copper red (Classic), dark brown pre-oxidised (Oxid), green pre-patinated (Patina), matt grey tinned (Zinn), superior reddish golden (Brass), reddish brown (Bronze) and copper/aluminium (Gold).
Aurubis works closely with architects to develop tailored surfaces and techniques, and its range of copper, and copper-alloy, materials and systems provides a rich copper palette for contemporary architecture. Surfaces available include traditional bright copper (Nordic Standard), brown pre-oxidised (Nordic Brown), pre-patinated (Nordic Green), blue pre-patinated (Nordic Blue), gold copper alloy (Nordic Royal) and golden yellow copper alloy (Nordic Brass).
Copper can be worked at any temperature and does not become brittle in cold weather. It is available in sheets or strips, and is generally regarded as a lightweight covering requiring a supporting substrate (such as 25mm boarding). Thicker, self-supporting copper panels are used for cladding. Copper is also available in prefabricated rolled profiles, flashings, shingles, gutters and down pipes.
Fully supported, sheet roofing copper is easily formed mechanically or by hand, on site or in the factory, to suit virtually any three dimensional shape including complex curves and details. Pitches from 5° to 90° can be accommodated, as well as negative pitches such as soffits.
The thin nature of copper sheet and the ability to produce slim joints between sheets - particularly when using the ‘long strip’ method to avoid horizontal joints - allow large, geometric shaped roofs and cladding to be finished with a visually continuous covering of quality.
Copper can satisfy the most exacting demands of modern architecture, providing both function and aesthetics, giving the designer real freedom with almost no limitations on roof form.
Copper can be 100% recycled. When a building reaches the end of its life span, the copper can be recovered, recycled and refined, and does not deteriorate during the recycling process. Any bits of copper which are not suitable for recycling can be sold as scrap metal to a dealer where they will be resold for reuse.
TECU® copper contains 40-80% recycled copper and KME now offers TECU® made from 100% recyled copper. Over the last few years, 97% of copper produced for Aurubis’ Nordic range has come from recycled material, which includes 50-60% internal processing scrap.
