摘要

The architectural building element (1) comprises at least one outer layer (2) consisting of an inorganic sand material embedded in a hardened bonding agent, and a foam insulation layer (3) which is directly foamed onto the outer layer. An Independent claim is also included for a method for producing such a building element. It involves infiltration of a compacted sand material with a hardenable bonding agent.
