DAYLIGHTING ROOF MATERIAL

PURPOSE:To manufacture a daylighting roof material being light in the weight at a low cost by attaching both the side parts of an intermediate lighting roof material consisting of a transparent synthetic resin film on the bottom plate of a side part roof material consisting of the metal plates having a meshed joint part. CONSTITUTION:The vertical plates 8 and 9 which project upwardly are continuously installed in bending at the outside edge parts of the bottom plates 5 and 6 of the side part roof materials 3 and 4 consisting of metal plates, and the meshed joint parts 1 and 2 the part of which is cut are installed at the upper edge part. Then, two side part roof materials 3 and 4 consisting of metal plates are arranged in parallel, keeping an interval. Then, both the side parts in the width direction of an intermediate daylighting roof material 7 consisting of light transmissive synthetic resin film are fixed on the reverse surfaces of the bottom plate 5 and 6 parts of the side part roof materials 3 and 4 by an adhesive.
