SmartGlass 60 is an optional high performance double pane glass (replacing our old Smart Glass) for use in vertical glazing areas, such as windows, doors, kickpanels and transoms. It provides your clients with 60% less solar heat gain per s.f./hr than clear double pane glass, and 28% lower transmission of damaging and harmful UV radiation than our former high performance “Smart Glass”. The solar shading performance of this glass is so remarkable that your clients can actually pull a chair up next to a south-facing window, and sit down and read a book without experiencing that “radiator effect” that one normally feels sitting next to a sunlit window.
