FIELD: construction.
SUBSTANCE: invention relates to construction, in particular, to building roof panels. Flame-treated heat insulation panel for roofs of buildings is presented, consisting of a layer of a heat-insulating material made of rigid polyurethane foam (PUF) or another equivalent material and, in particular, preferably from polyisocyanurate. Panel consists of an intermediate insulating layer, preferably in the form of a parallelepiped with flat surfaces, moreover, the above-mentioned intermediate insulating layer on at least two opposite surfaces, characterized by a larger surface area, provides a multilayer coating consisting of at least the following layers: a) one layer of metallized polyester film; b) one layer of plastic film; c) one layer of waterproof paper; d) one film layer based on a bitumen compound; e) one layer of non-woven polypropylene fabric.
EFFECT: technical result consists in heat loss reduction of a building.
