Why expanded clay?

Expanded clay masonry is used for external walls with expanded clay hollow blocks with thermal insulation inside with U-value 0,18 W/(m²K) to guarantee a very high thermal insulation in 425 mm thick (0,08 thermal conductivity). Party and internal walls are made of solid expanded clay blocks for good sound reduction. Thin joints of 1-2 mm allow a short construction time. The expanded clay blocks deliver a high fire resistance.
