Thermochromatic glass is laminate glass able to alter its visual characteristics by varying its opacity and color through the use of a particular interlayer with thermochromatic properties. The membrane becomes autonomously brighter or darker, without any mechanical or other input, following changes in ambient temperature and light conditions. This results in passive solar gains, increased solar control, and natural light transmission.


Ambient conditions change continuously, dictated by seasonal and spontaneous changes in climatic conditions.

That means that a particular glazing designed for high levels of light transmission will perform better in a cloudy day than it would during a sunny day.

Choosing to install tinted special glazing with a low light transmission coefficient would be favorable for a sunny day, however in a cloudy day, would turn the interior of a building dreary. The innovative technology of thermochromatic glass offers the ability to dynamically balance between light transmission and solar gain, adjusting to the ever-changing ambient conditions.

Thermochromatic glazing would gradually darken in the presence of abundant light during a sunny day, brighter hues would develop during the cooler early evening and morning hours, and a more neutral state would be adopted during a cloudy day. The thermochromatic interlayer can play a significant role in reducing energy costs related to temperature control and artificial lighting.

Additionally, thermochromatic special glazing retains all the safety and protection properties of a safety laminate. Finally, thermochromatic glazing allows for unobstructed viewing as it reduces the need for shades and other shading mechanisms.
