20 minute addition to the lineup
Pilkington has expanded its Fire Protection Glass product range to include a 20 minute Pilkington Pyrodur product. Pyrodur 20-104 is UL-listed and available in a thickness of approximately 1¼4''. Pyrodur blocks around 90 percent of radiant heat and can be used for interior applications including windows and doors. Pilkington also offers Pyrodur 20-200 in a thickness of .39'' and a complete product range of Pyrodur products for 45, 60, 90, and 120 minute fire resistance.

Passes the test
Aluflam has completed the UL fire testing of its 60-minute extruded aluminum curtain-wall system. The system can be specified for interior or exterior applications, and is designed to maximize light and vision while blending in with standard nonrated aluminum products. The system’s aluminum framing is combined with clear, safety-, and fire-rated glass by Vetrotech Saint-Gobain.

Floating glass fastening system
A corrosion-free glass fastening system has been developed by Novum Structures, formerly Mero Structures. The new Edge Clamped Glass (ECG) System is engineered to provide a clean, transparent way to fasten glazing directly to the supporting structure without the use of a standard aluminum-mullion support system. By eliminating the aluminum mullion, the glazing “floats” on top of the structure. This system, sealed around the glass panel’s perimeter by a wet silicone and silicone-gasket technology, creates a transparent glass envelope. ECG can be used to support monolithic, laminated, and insulated glazing systems. Novum Structures, Menomonee Falls, Wis. www.novumstructures.com [ Reader Service July 2006 # 220 ]

Controlling light and heat
In addition to various energy-efficiency upgrades, facility managers at The University of Colorado applied 8,800 square feet of V-Kool window film to prevent campus buildings from overheating. The V-Kool 40 product blocks 65 percent of solar heat while transmitting 42.8 percent of visible light, a condition that is ideal for the environment. The product’s colorless transparency and non-mirrorlike reflectance allowed managers to apply it selectively to windows in buildings where heat gain was an issue, while maintaining a uniform design.
