Technology That Makes All the Difference

RavenWindow transitioning technology is at the heart of our smart windows. It’s simple: the RavenWindow thermochromic filter is applied to the inside surface of the exterior glass pane of a double pane window. An air chamber separates the filter from both the interior glass pane and the standard Low-E coating. Together, it’s an unbeatable combination to keep buildings energy efficient year round.

The filter activates when the exterior glass temperature rises above the transition temperature point. The window then transitions to its tinted state, blocking solar heat from entering, minimizing glare, UV degradation and reducing the load on mechanical systems. During cooler months when solar gain is desired to help heat the building, the filter remains clear to let warming rays and light in.


It all happens automatically, with no manual adjustments or controls, additional wires or electricity. Once RavenWindows are installed, they’re ready to work. Whether you need a custom design for a new structure or retrofitting for existing windows, RavenWindow technology is the sustainable solution you’ve been looking for.

Make the transition...Intuitive. Logical. Smart.

The top dynamic window for new construction or retrofits, RavenWindow is ideal for both commercial and residential construction.

RavenWindow uses a patented thermochromic filter directly incorporated into the windows during manufacturing. The filter automatically transitions to a tinted state during hot conditions to manage solar heat flow, glare and UV degradation and clears during cold conditions, therefore harvesting solar heat flow and light.

No controls, no adjustments–the technology does all the work, for years to come.

Every RavenWindow is Smart

Smart is built right in to every RavenWindow, along with high performance. The thermochromic filter applied inside the glass unit during manufacturing is ready to perform as soon as your windows are installed. Because the filter responds directly to solar heat, your windows start saving energy from the first day of installation. As soon as the exterior temperature reaches the transition temperature, the window changes to a tinted state and remains tinted until the temperature drops to the clear state threshold. RavenWindow requires no programming or control settings – That’s the beauty of solar-intuitive technology.

Blocking solar gain in summer, allowing in the sunlight you crave in winter – how smart is that?
