Abstract: A quonset type arched roof shelter construction is disclosed. In one embodiment, the shelter is constructed of corrugated laminated fiberglass panels, each of which has a corrugated construction throughout the main central portion of the length thereof and a molded end portion at each end. The corrugations of each panel have a maximum amplitude midway between the respective end portions and with the amplitude being reduced as the corrugations taper into a generally flat configuration adjacent the end portions. The panels may have a length such as about two feet, with a structure of any desired length being obtained by joining overlapping end portions of successive panels. The number of plies in the laminated panels may be varied throughout the height of the structure and various reinforcing materials may be employed between laminations of fiberglass.
