Plasteco’s continuous vaulted skylight Model 300 (single glazed) and Model 301 (double glazed) are available in widths ranging from 3 ft. to 7 ft. with unlimited length. They are composed of pre-assembled half-dome or vertical ends and intermediate sections which are shipped K-D. The intermediate sections consist of flat acrylic sheets cold formed over pre-formed aluminum arches.
The curb frame comes with a self-adjusting counter-flashing to reduce the amount of air infiltration (or exfiltration) that occurs between the top of the curb and the skylight curb frame.
These skylights are light in weight and provide an economical solution to daylighting of relatively large rectangular areas. Since the skylight opening is rectangular the construction of the structural framing, curbs, roofing, flashing and the interior finish is simplified resulting in a lower completed cost.
Although the skylights are normally furnished K-D (except for the ends), Plasteco has shipped pre-assembled 20 ft. sections. The pre-assembled 20 ft. sections have special designed ends that can be mulled together with a special EPDM gasket. Projects consisting of 20,000 ft. have been installed using the 20 ft. pre-assembled sections.
Since skylights are not designed to support body weight, some method
of fall protection should be provided. See OSHA
Regulations on fall protection.
