Series 350, 500, 700, 850 and 1050

Series 350, 500, 700, 850 and 1050 are essentially the same skylight systems with interchangeable rafter sections. The rafters are 3-½” on the 350, 5” on the 500, and 7” on the 700. The rafters on the 850 are 8-½” and on the 1050 10-½.”

The interchangeable rafters allow for efficient use of frames for increasingly longer spans. The various mullions, perimeters, headers, etc, are used as appropriate in each condition.

Our engineers will assist in selecting the correct rafter and spacing for the job, taking into consideration such variables as loading and codes for the specifications and job site locations.

We have, on numerous occasions, bent the 350 rafter for glazing with bent glass. The photos above demonstrate a pair of 10′ wide x 225′ long skylights installed in the new Orlando Airport, North Terminal Expansion. They are aluminum framed skylights using our Series 350 frame which was custom bent for this job. The finish is clear anodized and the custom bent glass is clear 9/16″ Lami with a ceramic frit pattern furnished by Dlubak Corp. Custom Skylight Photos courtesy of PCL Construction.

Skin System

Our Skin System is a great solution for customers that would like to add glass panels or a skylight to an existing structural framework.

This product has most of the features of our 350/500/700/850/1050 series except the main rafter is not structural (it needs to be supported by the existing structural framework – most often steel or wood).

Since structural load calculations may not need to be done this can provide a very cost effective solution to adding a skylight to your project. This product seamlessly integrates into new or existing projects and can be a real asset to changes made late in the construction schedule.

The photos above feature the curved frame Series 500, glazed with bent 9/16″ HS Lami. It is supported on two sides against the walls, and at the columns which support the Walkway Cover Canopy. The Walkway Canopy is our Skin System applied to the existing support beams.

S50

The S50 is a glazing system designed by Gammans for large spanning projects with extremely heavy loads.

Walkable Skylights

With over 50 years of expertise in the skylight industry, our walkable skylights combine innovative design with unmatched durability. Engineered to handle foot traffic, these systems feature custom structural members that support a wide range of glazing configurations—ensuring both strength and visual harmony.

Each custom frame is precision-welded and shipped ready for installation
directly into the prepared opening. Once in place, flooring is installed around the skylight for a seamless, flush finish. Designed for impact resistance and long-term performance, our walkable skylights are more than just a functional feature—they’re a statement of quality and craftsmanship.

Custom Skylight Designs

Westin Peachtree Tower

This monumental landmark skylight was completely renovated using a Gammans Series 350 skylight framing system and GSS 518 mullions. Our system was selected for it’s flexibility of design, and performance. The re-glaze was done with a 9/16″ thick HS Lami. About 2 years following this renovation Atlanta, and this hotel suffered terrific damages from a tornado. Consulting engineers were called in to assess the damages; they were amazed at how well the skylight portion of the building had performed! Although 70 floors of curtain wall glass rained down on the skylight and cracked almost all of the skylight glass, nothing penetrated the PVB Inner-layer of the safety glass or damaged the internal framing. New caps and covers were furnished by GSS for the remedial work. In addition, Gammans was selected to provide design engineering and custom extrusions to rebuild the 10th floor swimming pool barrel vault skylight which had lost most of it’s original glazing. This unique skylight is operable over the pool.

Man in the Moon 

 The “Man in the Moon” was developed to be a functioning weather vane and stunning custom skylight. The skylight portion is an oculus that sits at the peak of a conical slate roof and self flashes. Due to construction conditions, it was required to be installed by crane and attached from the inside. A weather proof venting system was incorporated into the flashing flange.

 The moon sculpture is comprised of an aluminum face featuring 3-D gold anodized eyes and lips. Permanently sealed bearings and stainless steel shafts allow this work of art to pivot facing with the breeze. Gammans Skylight Systems is pleased to have been selected as the skylight manufacturer of this truly unique custom skylight.

Sciport Sundial

This custom built sundial skylight is installed at the Shreveport Science Museum (SciPort). The framing is a combination of Lite-Rail and a tapered steel sub-frame to support the center hub. The center hub was also designed and built by Gammans. The Gnomon is designed to be adjustable for proper alignment with the North Star and casts its shadow around the 180 degree arc of white translucent glass. Numbers have been set inside along the short vertical wall of the skylight curb that match the time of day to the sweep of the shadow. Architect: Alliance AE.

We create custom skylight systems for any project. Contact us for additional information.
