FIELD: construction.
SUBSTANCE: window profile with a blanket for obtaining of which the polymeric composition for joint extrusion is subjected to dual extrusion on one surface of the profile, extruded from the main extruder, and the polymeric composition for joint extrusion contains wood fiber, and the polymeric composition for joint extrusion contains the first source material for formation of primary colour, the second source material for formation of gray-scale colour and the third source material for formation of saturated tone colour, and the temperature of melting of the first source material is 160-165°C, the temperatures of melting of the second and third source materials are 175-185°C and the temperature of melting of the first source material is lower, than the temperatures of melting of the second and third source materials.
EFFECT: improvement of quality of the made profile, in particular its appearance due to minimizing of decolouration process.
