FIELD: building units, particularly combined elements and building envelopes.
SUBSTANCE: unit is made as parallelepiped frame having slot and extension of equal shapes and dimensions. Slot and extension are created on two parallel side walls. Side surfaces with slot and extension form masonry joint with interlock. Two other parallel side surfaces are outer and inner envelope surfaces. Closed heat insulation layers are arranged along frame height in central part and on peripheral parts thereof from inner side surfaces. Heat insulation layers are offset in opposite directions relative each other, extend towards lock beyond masonry joint and from ribs of equal thickness together with frame. Degree of heat insulation layers offset is selected in dependence of lock and heat insulation layer dimensions and is not more than 2/3 of lock height.
EFFECT: simplified structure and improved heat insulation properties, increased manufacturability and operational reliability, reduced labor inputs of wall unit mounting and decreased cost.
