EXTECH’s SKYGARD 3300 commercial skylight system is an aluminum mullion skylight that was designed with ease of installation in mind while being able to endure a wide range of weather systems. It is incredibly easy to install, lightweight, and durable.
The SKYGARD 3300 skylight is a non-structural 'skin' system, designed primarily for polycarbonate glazing, although glass can be used. The system requires continuous structural support and is ideal for over-glazing or retrofit applications where existing structural members will remain in place.
The SKYGARD 3300 is used in a wide range of building types, from airline hangars to industrial factories to recreational facilities.
For self-supporting and long-spanning skylights, see EXTECH's SKYGARD 3700.
Accepts glass, monolithic, or cellular polycarbonate sheets from ¼" (6mm) to 1" (25mm) thick
Deep glazing pockets (rabbet depth) accept thermal movement of thermoplastic glazing
Dry glazed, incorporating low friction gaskets to reduce noise caused by movement of the glazing
Glazing gaskets have a low coefficient of friction surface to allow for thermal movement of glazing
Finish on aluminum framing can be anodized or high-performance factory baked paints
Lightweight components designed to attach to the existing structure
Pressure equalization system
Plastic spacers for thermal improvement of the system as well as positive stops to control gasket pressure
Aluminum framing is overlapped at intersections for superior air and water resistance
Manufactured in the U.S.A.
Air infiltration (ASTM E-283): .03 cfm per square foot at 12 PSF
Water infiltration (ASTM E-331): No leakage at 12 PSF
