Glare? Overheating? Dim Sun with Thermochromic Glazing

Ravenbrick and Suntuitive offer glazing that tints under direct sunlight without electricity.

Another smart glazing product is about to emerge from the lab and into commercial production, giving projects more options in specifying windows that can block the sun’s heat—or let it in, depending on conditions.

RavenBrick, based in Denver, is wrapping up work on its facility and plans to begin production of RavenWindow by late spring 2014. RavenWindow is a filter that can be added to standard insulated glass units (IGUs) and will tint at a certain temperature, reducing glare and solar heat gain coefficient (SHGC)—with projects seeing up to 30% energy savings, according to the company. At the same time, Suntuitive from Pleotint offers another option in thermochromic glazing.
