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 10mm air gap behind the shell of Basalt slabs. It is a monument to this volcanic material, chosen for its character and resilience. For Basalt Products, tel 020 7407 1157, fax 020 7407 5364, or e-mail info@lavastonedesigns. co. uk
