Traditional windows serve one primary purpose - to allow light and air to enter buildings while providing some barrier against the elements. However, windows are quickly evolving to become much more than passive openings in walls and roofs. Emerging Smart glass technologies are enabling dynamic control over light transmission, thermal insulation, and more - paving the way for next-generation energy efficiency and user comfort.

The Science Behind Smart Window

Most Smart Window glass technologies leverage properties of liquid crystals and electrochromic materials. Liquid crystals are substances that flow like a liquid but whose molecules align in an ordered way similar to a solid crystal. When an electric current is applied, it alters the orientation of liquid crystal molecules and controls how much light can pass through. Meanwhile, electrochromic materials change color and opacity in response to small voltage differences, allowing dynamic tinting.

By incorporating these light-modulating components into window glazings, users gain the ability to adjust transparency on demand. Other emerging approaches involve integrating thermochromic materials that change properties in response to temperature, as well as integrating motorized blinds, shades and insulating panels. Combined, these various Smart glass technologies open up exciting new possibilities.

Light and View Control

One of the most basic yet useful Smart glass functions is adjustable light and view transmission. By activating electrochromic glazings, users can precisely tune how much natural light enters a space and the external view clarity. This allows balancing light levels and glare with maintaining visual connections to the outdoors.
