A skylight construction and method of making same are provided wherein such construction comprises, a support, an outer sheet made of a light-transmitting material and having a peripheral portion adjoining the support, and an inner structure made of a light-transmitting material and having a peripheral edge portion attached to the support defining a first air space between the outer sheet and the structure with the inner structure comprising a pair of inner sheets each made of a light-transmitting material and with the inner sheets being held in spaced relation defining a second air space therebetween such that the sheets and first and second air spaces enable provision of the skylight construction having minimum weight yet providing minimum heat loss in winter and minimum heat gain in summer.

In a method of making a skylight construction comprising the steps of; providing a support; providing an outer sheet made of a light-transmitting material and having a peripheral portion adjoining said support; disposing an inner structure made of a light-transmitting material and having a peripheral edge portion against said support; and attaching said peripheral edge portion to said support defining a first air space between said outer sheet and said structure; the improvement comprising the method steps of, constructing said inner structure of a pair of flat sheets each made of a synthetic plastic light-transmitting material, fixing said flat sheets in spaced parallel relation solely using a plurality of spaced parallel sheets to define a second air space therebetween, said ribs and flat sheets being made as a single-piece structure by extrusion process and of the same synthetic plastic material with said making and fixing steps being simultaneously achieved during said extrusion process, said sheets and first and second air spaces enabling provision of said skylight construction having minimum weight yet providing minimum heat loss in winter and minimum heat gain in summer.
