The best thing to happen to windows since, well, ever.

Halio® looks just like natural glass and then the magic happens. Halio magically tints to cool gray shades when the sun gets a little too hot or a little too bright. The first and only smart glass that's responsive and looks natural at the same time. And they're good for the planet.
