FIELD: construction.
SUBSTANCE: objects of this invention are multilayer heat insulation construction panel (100) and method of its production. This panel comprises: main layer (1) of heat-insulating material containing first surface (10) and opposite second surface (20); first protective layer (2) of main layer attached to main layer at said first surface (10); second protective layer (5) of main layer attached to main layer at said second surface (20). At least one of said first (2) and second (5) protective layers comprises: reinforcing layer (3) of fibrous material; fire-resistant (4) and heat-insulating layer; lining layer (6) of reinforcing layer (3); binding layer (7) located on surface (8) of fire-resistant layer (4), so, that said fire-resistant layer lies between lining layer (6) and binding layer. Binding layer (7) is made by spraying water solution of sodium silicates on surface (8) of fire-resistant layer (4).
EFFECT: invention increases fire resistance and heat resistance of panel.
