ABSTRACT:
The invention provides a light transmitting roofing or cladding panel comprising a translucent rigid plastic sheet formed into a corrugated structural panel wherein parallel slopes of the corrugated panel are provided with a reflecting and opacifying material to form alternate light transmitting and light reflecting zones of a fixed ratio whereby said panels are adapted upon proper positioning relative to the sun's apparent passage to allow natural sunlight to pass therethrough while at the same time minimizing penetration of the sun's heat radiation. The invention also provides a method of providing natural sunlight for buildings, workshops and warehouses while minimizing penetration of the sun's heat rays comprising positioning said panel in a structure with the translucent light transmitting zones thereof substantially facing north.
