FIELD: civil engineering, in particular, external guards of buildings; may be used in construction of residential and public buildings. SUBSTANCE: exterior guard has exterior brick wall carrying loggias and provided with pilasters and made with periodically located in height from internal side of wall, projections of header bricks extending up to stop of middle wall with end faces coated with antifriction material; interior wall connected with exterior wall by braces. Interior wall has rows extended to stop of middle wall made of heat-efficient material and is located in air gap between interior and exterior walls. Braces are made in the form of bars with cross-section multiple to brick sizes of structural heat-insulating material and located at the level of structures between ceilings and floors. Brickwork of middle wall in places of passage of braces has holes filled round braces with heat-insulating material. EFFECT: improved heat-insulating properties of guard and excluded reciprocal influence of walls with different deformation characteristics. 2 cl, 3 dwg
