<p>PCT No. PCT/CH95/00041 Sec. 371 Date Aug. 16, 1996 Sec. 102(e) Date Aug. 16, 1996 PCT Filed Feb. 24, 1995 PCT Pub. No. WO95/22886 PCT Pub. Date Aug. 31, 1995The web plate consists of two panes (1) and a plurality of webs (2) interconnecting the panes (1). The width of the webs is substantially greater than the spacing between the webs. The longitudinal extension of the webs (2) is horizontal. The webs (2) form an acute angle ( alpha ) with the panes (1). The cross section on the lower side of some of the webs (2) is saw-tooth shaped. This ensures that, when the sun is high in the sky, most of the sunlight is deflected outwards. The narrow horizontal cavities (3) between the webs (2) keep heat losses by convection to a minimum, thus ensuring a very good thermal insulation.</p> |
