FIELD: physics. n SUBSTANCE: element is characterised by at least one combination of substrate material selected from polymer, a lacquer coated substrate, fibre material, a substrate with hydraulically bound mass and/or non-woven material, containing components consisting of inorganic and/or organic light filler, hollow spaces formed in the substrate material by gases, dyes, organic pigments, inorganic pigments, inorganic and/or organic nanomaterials. The combination has thermal conductivity of not less than 0.4 [W/m·K], apparent density low of less than 1.4 g/cm 3 , average reflection in the 400-700 nm wavelength range of visible light less than 50% and average reflection in the 700-1000 nm wavelength range of near-infrared radiation greater than 50%. n EFFECT: low heating in the sun, lower heat output compared to conventional dark surfaces, heat insulating effect. n 26 cl, 10 ex, 11 dwg |
