Abstract
Abstract A laminate particularly usable for a greenhouse or as a skylight has a glass sheet to one side of which is bonded a synthetic-resin panel formed by inner and outer synthetic-resin plates that extend parallel to but are spaced from each other by a plurality of transverse synthetic-resin webs that unitarily interconnect and space the plates and form between them a plurality of dead-air spaces. The inner plate is bonded to the face of the glass sheet, and the dead-air spaces are sealed at the periphery of the laminate.
