Thermochromic window

RavenBrick announced that the development of RavenWindow version 2.1 is complete and will be available from its manufacturing facility in May Industry products 2013. Company officials say 2.1 offers significant improvements over the previous version, including an increase in visual light transmission of 15 percent and the ability to re-size at the fabricator level. RavenWindow is a filter installed inside an insulating glass unit. It is customized at the time of manufacture to remain in the clear state, allowing solar heat into the building when desired, and then transition into the tinted state, blocking solar heat, without the view to the outside being compromised, according to a release.
