| 摘要 |
<p>The invention relates to a plastic body consisting of a base moulded body which is produced from a transparent, thermoplastic base material, and which consists of at least two opposing flat layers (1a, 1b) which are interconnected by means of vertical or diagonal connecting elements (2). One of the flat layers (1a) is provided with an additional layer (3) consisting of a plastic matrix in a transparent, plastic base material. The invention is characterised in that the additional layer (3) is an IR-absorbent layer containing at least one IR-absorber which does not impair the transparency of the plastic body and has an average transmission of less than 80 % in the region of the near-infrared radiation (780 nm to 1100 nm). The plastic body has a light transmission (D65) of between 15 % and 86 %, a maximum heat transition coefficient of 4 W/m2K and a minimum Sk value of 1.15. The invention also relates to the use of said plastic body as a glazing element, a roofing element or a heat insulating element.</p> |
