Glass Walls Provide Transparency in Commercial Buildings

Technical Glass Products (TGP) has introduced a butt-glazed, fire-rated framing system for glass walls that eliminates the need for colored internal spacers or vertical mullions between adjoining pieces of glass. With a 5 millimeter vertical butt joint and available in nearly 10-foot heights, the Fireframes ClearView System allows design professionals to create fire-rated glazed walls with nearly colorless transitions between glass panels, allowing for transparency through hallways in commercial buildings.

Comprised of butt-glazed Pilkington Pyrostop, a fire-rated and impact safety-rated glass, with a heat resistive perimeter frame, the Fireframes ClearView System won an honorable mention in the 2016 “Best of Products” Awards from The Architects Newspaper. Pilkington Pyrostop glass is comprised of layers of Pilkington Optiwhite float glass and intumescent interlayers (multi-laminate, not a polymer gel). The perimeter of each butt-glazed elevation is held in place by the designer’s choice of TGP’s Fireframes fire-rated frames or L-angle steel from local steel fabricators.

The Fireframes ClearView System is fire-rated for up to 60 minutes, passes the required hose stream test and protects against radiant and conductive heat transfer per ASTM E-119. The system is impact safety rated, meeting CPSC 16CFR1201 (Cat. II). Classified and Labeled by Underwriters Laboratories, Inc., it is also approved for use in New York City and in Los Angeles.
