Abstract (en)
[origin: EP0933489A1] An extruded alveolar panel (1) is described, comprising two parallel flat sheets (2, 3) spaced apart from each other and connected by a plurality of ribs (4i) which are parallel to each other and incident with respect to the said two sheets, in which the said two sheets are made of transparent material, and the said ribs are made of opaque material suitable for reflecting and/or diffusing to a pre-determined extent the rays of light incident thereon, increasing dimensional stability and load-bearing capacity. <IMAGE>
