SKYLIGHT CONSTRUCTION AND METHOD OF MAKING SAME

A skylight construction and method of making same are provided herein. The 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 flat inner sheets each made of a light-transmit-ting material and with the inner sheets being held in spaced relation defining a second air space therebetween, the means consisting solely of a plurality of identical spaced parallel ribs perpendicular to flat sheets, the ribs and flat sheets being an integral single-piece structure. The sheets and the 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.
