Mendiger Basalt Lava was used to build Ortner & Ortner's Ludwig Museum of Modern Art in Vienna, for the facade, the curved roof and the inside walls.
The outer wall is 500mm thick, with a 10mm air gap behind the shell of Basalt slabs. It is a homage to this volcanic material, chosen for its beauty and resilience. For Basalt Products, tel 020 7407 1157, fax 020 7407 5364 or e-mail info@lavastonedesigns. co. uk
