Introduced to the North American market last June at the AIA show in Miami, the GlassX glazing system incorporates a salt-hydrate phase change material (PCM) that stores energy from the exterior temperature and reuses it to either heat or cool the building as needed, putting less pressure on the mechanical HVAC systems. Achieving U-values up to 0.08, GlassX is a quadruple-glazed sealed unit that is made up of three separate insulating glass units (IGUs), a prismatic solar filter that deflects high-angle sunlight, two low-E coatings, and a PCM core. “GlassX would have a similar R-value to something like concrete, which is pretty much unheard of in the glassfacade arena,” says Ryan Dennett, president and C.E.O. of Greenlite Glass Systems, the exclusive distributor of GlassX in North America.
