Our Story
Formerly known as GSI, or Glazed Structures, Inc., with over 40 years of experience in the industry, E-GSI continues to lead the industry with our commitment to excellence in the development, production, and installation of virtually any skylight system, pre-engineered or custom. We have recently expanded our capabilities and product line to include shading systems and retractable roof systems, putting us in the forefront in the glass and glazing industry.
Our team of highly experienced engineers, craftsmen, and installers has initiated the development and refinement of twelve of the most versatile, comprehensive, quality engineered overhead glazing systems available on the market.
E-GSI's years of experience in developing quality glazing systems have been incorporated into high-tech, leak-free insulated and economical structural polycarbonate panel systems. Panel sections (6' wide up to 22' long) are pre-glazed and designed to lock together with the patented lock seal design. No field fabrication is required.
E-GSI's integral condensation gutter and weeping system carries all moisture to the outside. Filling the demand for high-quality factory-glazed skylight systems, we have pushed the envelope of excellence offering custom or standard skylight systems that are 100% factory assembled and shipped to the field completed. Without proper condensation control, skylights not only become unsightly, but they can lead to interior leakage, staining, and thousands of dollars worth of damages.
