FIELD: civil engineering. SUBSTANCE: wall includes stones which are square on stone facade sides with through slots which are parallel to the stone facade sides. The stones are laid on mortar without binding. Each following stone in each masonry line is revolved through 90 degrees with regard to the previous stone. As this takes place, the mortar is applied to lateral sides of the stones. Face sides of the latter are joined dry to lateral sides of adjoining stones covered with mortar. With dimensions of the stone 250 mm by 250 mm on the facade side and 210 mm stone thickness the wall may have 1.75 degrees of Centigrade per square meter per Watt thermal resistivity; 0.12 Watt per meter per degree of Centigrade heat conductivity coefficient; 255 kg weight per square meter. EFFECT: high performance. 7 dwg
