To fill the demand for quality pre-glazed
skylights, GSI has developed a wide range of modular skylight systems
that are factory assembled and glazed. These units are designed to reduce
field labor cost and provide a quality installation at a fraction of the cost of
field assembled and glazed design. |

Glazing:
The Pre-glazed or Modular Systems are
available in acrylic, polycarbonate, and safety glass in single glazed or
insulated designs. |

Thermoformed Capabilities:
We have the largest skylight thermoforming
ovens in the Midwest. Thermoforming plastics into dome, pyramid,
polygons, extended ridge, and circular units can be produced from one sheet
of plastic in our 13'x16' production ovens. |

Custom Shapes:
Special shapes and sizes are not a problem

and frame finishing can all be produced by our in-house design and
manufacturing services. |

This skylight had a
perimeter curb and center beams made of cedar. GSI
manufactured the skylight system to sit over the existing curb and
