FIELD: construction.
SUBSTANCE: building panel, in which on a surface of a basic element there are the following components formed in the specified order: an impregnating coating film, a water-soluble coating film, a colourless coating film based on a dissolvent and an upper colourless coating film, besides, the water-soluble coating film is formed from a synthetic resin and a refractory reagent; the upper colourless coating film is formed from a resin hardened under exposure to ultraviolet radiation, and a refractory reagent; the volume of the refractory reagent in the water-soluble coating film is equal to 10 - 50% by weight relative to solid particles of the specified water-soluble coating film; the volume of the refractory reagent in the upper colourless coating film is equal to 5 - 20% by weight relative to solid particles of the specified upper colourless coating film; and the highest caloric power measured in accordance with ISO 5660 for 20 minutes using a conical calorimeter makes less than 8 MJ/m2.
EFFECT: higher refractory property and designability.
