<p>The compound thermal insulation system is used, in particular, for fixing on a building wall having a light-absorbing wall outer surface. It comprises an at least partially transparent thermal insulating material and on the outside a largely transparent plaster-like coating. The total optical transparency of the system is lowered to light transmission values of less than 0.2 in the summer period in conjunction with high xenith angles of the sun (from 60 DEG relative to the normal to the wall) by the addition of pulverulent substances having a particle size of less than 5 mu m and a refractive index of between 1.45 and 1.65.</p> |
