How Smart Glass Works

How Smart Glass Works

Glass Apps® Smart Glass is a laminated glass product consisting of a Polymer Dispersed Liquid Crystal (PDLC) film sandwiched between two layers of glass and two layers of conductive interlayers. The PDLC film is what allows you to change the visual appearance of the glass from opaque to clear on command (or dim anywhere in between).

Our UL approved technology provides unprecedented control over the amount of light, privacy and heat that enters a space and is ideal for Residential, Commercial Interior, Retail Store Front, Healthcare, Higher Education, and Government applications. Glass Apps® Smart Glass can be custom made in a variety of shapes, sizes, and compositions.

PDLC Smart Glass Technology

Glass Apps® Smart Glass is a state of the art laminated glass with a liquid crystal PDLC interlayer sandwiched between two sheets of glass.
Finished Smart Glass

How It Works

Smart Glass in its "off" state has a frosted or opaque appearance because the PDLC (Polymer Dispersed Liquid Crystal) remain in a randomized configuration that refracts the light that enters the mixture.

In the clear, or "on" state, an electrical current is passed through the PDLC (Polymer Dispersed Liquid Crystal) interlayer aligning the microscopic crystals along a number of parallel axes, thus allowing vision through the glass.

UL Listed

Glass Apps® is one of only two UL Listed smart glass products on the market. State laws require that electrical fixtures be tested by a recognized, independent safety-testing agency before they can be legally sold and installed. We offer a UL/CSA listed finished glass option that will speed up approval and reduce the likelihood of code issues when being inspected.
