Channel glass and IGU vision lites are installed in the same frame, achieving minimal tie-ins, in a curtain wall designed collaboratively by the architects and Bendheim. Photo by Alex Fradkin. CHANNEL GLASS’ TEXTURED SURFACES HIDE WATER STAINS & DIRT Bendheim channel glass is easy to maintain. The textured glass surfaces mask the appearance of water stains and dirt, making it easier to care for than conventional flat glass. When cleaning the channel glass is required, we suggest rinsing with water or a cleaning solution. Nonabrasive glass cleaners may also be used.
