FIELD: civil engineering, erection of new buildings and structures and reconstruction of existing buildings and structures. SUBSTANCE: wall of building or structure encased for warmth-keeping includes partitions, door and window apertures, heat- insulation blocks and fastening members. Blocks, plates or slabs made of wood- mineral or wood-concrete materials demonstrating thermal conductivity coefficient K=0.06-0.15 kcal./m.h.Co, volume weight 300-600 kg/cu m, water absorption coefficient 6- 10% and stiff porous structure are utilized in the capacity of heat-insulation blocks. Heat-insulation blocks are placed on internal or external side of wall. Blocks, plates or slabs are fixed with hardening solution or anchors installed along perimeter in points of match of faces or with hardening solution and anchors at same time. Heat- insulation blocks can have stratified structure comprising two-three plates or slabs made of wood-mineral or wood-concrete materials and interconnected by means of spacers or adhesive. Decorative-lining or finishing layer can be applied to heat- insulation blocks, plates or slabs. EFFECT: reduced usage of metal, simplified technology of warmth-keeping, ecological safety. 3 cl, 3 dwg
