FIELD: construction.
SUBSTANCE: invention relates to construction. Energy-efficient fire-resistant multilayer insulating panel consists of a constructive-forming layer of foam-aluminium closed-cell or open-cellular structure and subsequent deposited on at least one side of bulk-forming, heat-insulating and a binder layer of a rigid foamed polymer of a closed cellular structure, a fire-resistant foam-mineral rigid closed-cellular layer in the form of plates joined into the lock, and a finishing layer from generally applicable non-combustible and low-combustible construction materials.
EFFECT: invention provides high structural strength of the panel, low heat conductivity and high sound absorption and environmental friendliness of the panel.
