FIELD: building, particularly bridge-building, road building, for erecting roof, floor structures, as well as underground structures including tunnels, etc.

SUBSTANCE: insulation material comprises basic layer and two layers arranged from two sides of the basic layer and formed of bitumen-containing compositions. Web of porous fibrous material is arranged on surface of one bitumen-containing layer. The web is formed of puncture-resistant textile material having barrier, draining, reinforcing, separating and filtering properties. The textile material has surface density of not less than 70 g/m³, tensile strength of not less than 50 kgf/5 cm and thermal conductivity of not more than 0.17 W/m·deg.

EFFECT: increased moisture protection and atmospheric precipitation draining ability, reduced noise, as well as improved protection of water- and noise-insulation layers against mechanical damage.
