Plasteco’s Half Round Structural Barrel Vault Skylights available in widths eight to sixteen feet with lengths unlimited, provides the designer the opportunity to present an eye-catching exterior to the building and at the same time provide daylight and increase the openness of the building interior. Barrel vault skylights have been used as a means of identifying retail establishments, for building entrances and walkway covers. The hemispherical shape adds height and a refreshing openness to the interior of any building. The feeling of greater space created by barrel vaulted skylights is both aesthetic and psychologically refreshing.

Since skylights are not designed to support body weight, some method of fall protection should be provided.
