Energy Glazed Systems > PRODUCT > Structural Polycarbonate - SP-7000

Single slope, shed, pyramids, polygons, ridge and custom type skylights in all pitches. Free spans possible up to 40' rafter lengths depending on geometry and design loads.

Complete plans, details and specifications for all of EGSI's Skylight system are available on request.

Skylights, atria, solaria, greenhouse. lobby enclosures, malls and pool areas. Design possibilities are unlimited. EGSI's integral condensation gutter and weeping system carry all moisture to the outside. This system is concealed within the top of the rafter/purlin.

Electrostatic Powder coat finishes available from Dupont, Morton and Tiger Drylac.

All flush tubular extruded aluminum sections have concealed condensation channels with no projecting troughs to detract from slim-line silhouette. All structural members are extruded aluminum.

EGSI's glazing systems are designed to receive structural polycarbonate panels in thicknesses from 6mm to 25mm. EGSI's years of experience in developing quality glazing systems have been incorporated into high-tech, leak free, insulated and economical structural polycarbonate/fiberglass panel system. 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.


Multiwall polycarbonate is a lightweight material that is used in the construction industry to reduce building costs while guaranteeing compliance with loading requirements.

A key feature of polycarbonate is its transparency. Multiwall polycarbonate enhances daylighting when integrated into roofing systems, walls, and skylights. It creates a more comfortable ambience while also ensuring good thermal insulation. Polycarbonate can be suitably tinted to modulate light transmission, optimize shading and thus reduce overheating inside the building. Colored pigments are used to achieve pleasant color effects to satisfy the most demanding aesthetic and architectural requirements.

We supply an extensive range of products for use in the construction of translucent roofing and walls, skylights, fixed and operable insulated windows. Our continuous research has led to the development of a series of steel and aluminum accessories to complete the range. Our polycarbonate systems are designed to make installation simple and safe, and ensure compliance with most building codes. Our products are all tested and certified for fire rating, loading and thermal performance.


Gallina multiwall polycarbonate is tested to ASTM standards for hail impact to ensure against the most inclement weather conditions. Gallina co-extrudes a high-performance U.V. coating to our exterior surface to ensure optimal performance under prolonged exposure to the harshest sunlight. Our products are also third-party tested and certified by ASTM standards for accelerated weathering.

Multiwall polycarbonate has a particularly high impact strength. Our products meet the requirements and safety standards for translucent glazing in public and private work environments.

The process of extruding multiwall polycarbonate involves very low energy consumption and has a minimal impact on the environment. Polycarbonate is an energy-efficient solution and is 100% recyclable at the end of its life.
