Gauzy LCG® (Light Control Glass) smart glass is switchable glass, providing instant transparency or privacy at the touch of a button and revolutionizing the way people interact with glass, light and the surrounding environment.


In the simplest definition, smart glass LCG® technologies alter the amount of light transmitted through typically transparent materials, allowing these materials to appear as transparent, translucent, or opaque. The technologies behind smart glass help resolve the conflicting design and functional demands for balancing the benefits of natural light, views, and open floor plans with the need for energy conservation and privacy.


LCG® is available in various colors and custom dynamic patterns.

Switchable glass windows, doors, and partitions are beginning to appear in the residential sector. To make homes more energy efficient, solar control PDLC can be used to reduce IR light which creates heat, and SPD can be used to shade, both keeping spaces cool and lowering HVAC costs.

High Temp LCG® glass can be used on LC based switchable glass for outdoor applications and exterior windows that face the street or neighbors, so privacy can be achieved without the need for curtains or blinds.

Electrically switchable glass partitions and walls add adaptability and give a “WOW” effect to interior office designs. Switchable glass can easily transform a space from open and shared, to private and intimate, and anywhere in between with dimming features.

This is especially helpful in agile work environments based on flexible open floor plans. An ideal solution to support minimalist interior design while maintaining privacy and maximizing the space of a modern hotel suite.

Elegance and efficiency are hallmarks of PDLC smart glass in hotel guest rooms as this technology offers an ideal solution for including a cozy lounging and sleeping space, clean and relaxing bathroom, and privacy for intimate moments in a way that feels spacious within limited square footage.

Smart glass is eliminating the need for traditional drapery and curtains, a valuable feature for hospitals and medical facilities. Research shows that patient-privacy curtains harbor bacteria responsible for spreading disease. Moreover, glass hospital room partitions better isolate sound, creating an extra layer of confidentiality.

With PDLC partitions, hospital staff can check on patients without entering a room, reducing disturbances and chances of contamination and improving the overall patient recovery process.

Smart visual merchandising allows retailers to take full advantage of their store’s most valuable real estate, the storefront. Smart glass technology allows 100% utilization of storefront windows for advertising or can be made completely transparent to allow views into a store. A retailer’s windows can become rear-projection screens promoting retail branding and products without permanently blocking windows with traditional signage or tv screens.

What is
Made of?

Polymer Dispersed Liquid Crystal (PDLC) Film


The technology behind PDLC films used to create smart glass contain liquid crystals, a material that shares characteristics of both liquid and solid compounds, which are dispersed into a polymer.

PDLC switches glass from dimmable degrees of opaque to clear in milliseconds. When opaque, PDLC is ideal for privacy, projection, and whiteboard use.

Solar reflective PDLC, such as the one developed by the material science company Gauzy, allows for IR light (which creates heat) to be reflected.

How LCG® Works.

Active smart glass technology allows for the control of various forms of light (visible, IR, UV) with electricity. With electricity, glass is switched from opaque to transparent, allowing for dynamic light control.

When off, particles are scattered creating opacity for privacy, shading, solar control, or projection.

When on, particles align, allowing light to pass through creating transparency for an open atmosphere and natural light.
