ADDITIONAL HEAT INSULATION OF BUILDING WALLS Russian patent published in 2000 - IPC

FIELD: heat insulation of building outside walls with controlled thermal condition, mainly additional heat insulation from the outside of the walls of buildings being erected or in service. SUBSTANCE: heat insulation of building walls comprises a heat-insulating lattice of convex-shaped volumetric members rigidly tied together in correct order, arranged with formation of intervals between them providing for vapor permeability in the direction perpendicular to the wall surface, protecting coating, ventilating ducts of a great number of alternating expansions and reductions and bracings passing through the cross intervals between the volumetric members of the lattice, and enveloped by a layer of cement-containing compound. EFFECT: enhanced heat- insulating efficiency, rigidity of bracings, enhanced reliability especially in seismic conditions, enhanced hygiene of heat insulation. 4 cl, 3 dwg
