ABSTRACT:
A light transmitting building panel comprising a flat central sheet and upper and lower corrugated sheets secured to the opposite faces of the flat central sheet, thereby to provide a set of upper cells and a set of lower cells. The upper corrugated sheet is laterally offset relative to the lower corrugated sheet whereby each upper cell is positioned intermediate of adjacent ones of the lower cells and whereby heat conduction between the internal and external surfaces of the panel is minimized. The flat central sheet and the upper and lower corrugated sheets are formed from a light transmitting glass fiber reinforced plastic. The present building panel is particularly useful in greenhouses as roof panels and wall panels. The long span capability, the light transmitting characteristic and the unique cell arrangement of the present building panel are advantageously employed in greenhouses.
