Materials made from copper and copper alloys are regenerative natural products and recycable without any loss of quality.


TECU® products for external cladding and roofing of buildings are manufactured exclusively from copper and copper alloys. Thus, the idea of sustainability is “in their very nature”. Another decisive advantage is the certification as an environmentally friendly building product in accordance with ISO 14025 and EN 15804.

All TECU® Classic, TECU® Oxid and TECU® Patina products are entirely made from 100% recycled material! This substantial material benefit is an important argument for modern architecture, especially for buildings requiring a LEED, BREEAM or DGNB certificate. TECU® Ecological Copper complies in all properties with materials made of new metals and surpasses all requirements of the European standard EN 1172.
