FIELD: process engineering.
SUBSTANCE: invention relates to construction material, particularly, to insulation veneers. Proposed method comprises mixing polystyrene with nucleating agent composed of the mix of granulated talc with inorganic additives, i.e. silicon dioxide, titanium oxide, magnesium hydroxide, kaolin, randanite, fusing said mix in extruder, adding cellulating agent to said melt and extruding via T-die to form the board.
EFFECT: better manufacturability.
