GlassBuild America is underway this week in Las Vegas, where exhibitors are showcasing the latest products, technologies and equipment for doors, windows and glass. Vitro is getting in on the action with smart glass, while H.B. Fuller is rebranding its Ködispace 4SG line of thermoplastic spacers. Meanwhile, one machinery company is making it easier for manufacturers to produce standard double- and triple-pane insulating glass units (IGUs), along with thin triples and quads—all on the same line.
