Structural Barrel Vault Skylights - Low Rise
Plasteco's Structural Barrel Vault Skylights provide an economical and practical means of presenting daylight and spaciousness to a lobby, atrium or the interior of a building. They have also been used as entrance canopies, walkway canopies and as a cover between adjacent buildings.
They are available in widths from 8 ft. to 24 ft. with lengths unlimited, single or double glazed. The curved aluminum rafters and acrylic glazing combination results in a lightweight economical skylight.
Since the skylight opening is rectangular the construction of the structural framing, curbs, roofing, flashing and the interior finishing is simplified resulting in a lower completed cost. Since skylights are not designed to support body weight, some method of fall protection should be provided.
