FIELD: building, particularly to erect roofs. ^ SUBSTANCE: vented roof comprises roof panels serially laid on roof base, heat insulation, concrete and waterproofing layers and a number of vent channels connected one to another by main - collecting channels or channel with discharge pipe. Heat insulation layer is formed of polystyrene-concrete units with through longitudinal channels, which are laid between end faces and spaced apart to create main - collecting channels or channel. Longitudinal through channels extending transversely to end faces create vent channel system. Additional layer formed of porous polystyrene-concrete is located between roof base, namely roof panels, and above polystyrene-concrete units. Vapor sealing layer is arranged between polystyrene-concrete units and concrete layer. Polystyrene-concrete units include connecting inserts made of foam plastics and having widths less than that of through channels. ^ EFFECT: improved heat and waterproof properties. ^ 5 cl, 3 dwg |
