Claims (2)

1. A flat building envelope comprising heat-insulating and structural layers made respectively of an insulating material and a mortar based on cement binder as a whole, characterized in that to increase the reliability and heat-shielding properties of the structure, the heat-insulating layer is made of lightweight material with sampling the corner edge along the perimeter with a bevel over the layer thickness inwardly angled 70-80 ^o for anchoring therein mortar structural layer, wherein elichina anchoring depth and width equal to the thickness of the structural layer and is 10-30 mm, and the volume of the heat insulating layer is 70-90% of the total cell volume. 2. A method of manufacturing a flat building envelope, comprising preparing a building mortar of a structural layer, filling the mold with a mixture, installing a prefabricated insulating element in the mold and hardening, characterized in that the installation of the insulating element pre-treated over the entire surface in the zone of contact with the structural layer of water the dispersion of a mixture of latex and liquid glass at a ratio of 1: 1-0.5 and a temperature of 30-35 ^o With subsequent exposure at a temperature of 20 ± 2 ^o C until the moment of film formation, produce in a cement mortar of the structural layer, containing, parts by weight:
Cement - 100
Sand - 100-200
Expanded clay dust - 20-50
Latex - 10-30
Liquid glass - 5-15
Water - To a working consistency
and prepared by successive mixing of cement and expanded clay dust with 50% mixing water, then with a mixture of latex and liquid glass with 50% mixing water, then sand, followed by vibration compaction with a uniformly distributed force of 0.005-0.01 MPa.
