Unlike “electrochromic” glass, SPD-SmartGlass tints instantaneously, no matter the size of your glass panel. Change the tint of your glass at the push of a button, or automatically with sensors.
Enjoy precise control over the transparency of your glass
Control your electronically dimmable glass from fully clear to extremely dark, and to any level of tint in between. Enjoy the views without squinting at the sun.
Blocks heat even when your glass is clear
SPD-SmartGlass blocks 95% of heat in its tinted state. But it also significantly blocks heat in its clear state. Improve the energy efficiency of your space by installing

FAQ
Frequently Asked Questions
Is SPD-SmartGlass offered on any substrates besides glass?

Our technology is film-based, which enables maximum design flexibility. The film can be laminated into glass, any type of plastic, thin chemically strengthened glass (e.g. Gorilla Glass), hurricane or security glass, or a combination of substrates.

Does SPD-SmartGlass also block harmful ultraviolet light?

Yes – SPD-SmartGlass blocks 99%+ of harmful UV light at all times, providing protection for people and light-sensitive furniture, carpets, artwork and artifacts. SPD-SmartGlass fabrications that block UV light up to 400 nm are also available.

How does SPD-SmartGlass work?

SPD-SmartGlass uses patented SPD technology with a light-control film laminated between glass or plastic substrates. The SPD film, a ‘light valve,’ contains microscopic particles that align when voltage is applied, allowing light to pass through. Adjusting the voltage controls the level of tint.

How much does SPD-SmartGlass cost?

Research Frontiers does not sell SPD-SmartGlass products but connects you with licensed partners who fabricate and sell the finished end-product.

How do I control SPD-SmartGlass products?

SPD-SmartGlass products can be controlled via simple switches (similar to dimmers), push buttons, motion detection, smart device apps or home automation systems.
