Halcyon Shades

I have Halcyon shades in all windows in my house in Southern California that get sun and I love them. Unlike most products advertised as solar shades, these are transparent allowing undistorted views to the outside while providing some measure of invisibility for those looking from the outside into the house. They reflect sunlight unlike most solar shades which block a part of the sun coming in. The metallization of a plastic film is the same technology used to manage heat on satellites out in space. They mount on the inside of the window and can be raised or lowered the same way any window shade can be adjusted. In some windows, I use them in conjunction with more opaque coverings. The only issue I have is that I'd like to put them in my retirement home and so far, haven't found anyone willing to figure out the Halcyon connection. Still looking though. Finally, because of the technology, they only come in limited "colors", silvery and pale brown; they are not a substitute for standard sun-blocking shades.
