What Is Smart Glass?

Smart glass, also known as switchable or dynamic glass, is a type of glazing that can change its optical properties in response to electricity or light. Different smart glass technologies are designed for different purposes, including privacy, solar control and glare reduction.

Main Types of Smart Glass

1. EC Smart Glass

Electrochromic (EC) smart glass uses a functional coating integrated into the glass unit. It gradually changes its tint level to control sunlight, glare and solar heat while maintaining outward visibility. EC glass is commonly used in architectural IGU systems.

2. Laminated Smart Glass

PDLC, PNLC, DLC and SPD technologies use a functional film laminated between glass substrates.

• PDLC / PNLC: Instant visual privacy

• DLC: Privacy with darker solar shading

• SPD: Dynamic light and solar control

The functional film can be incorporated into laminated or insulated glazing systems depending on the technology and project requirements.

Where Is Smart Glass Used?

Smart glass can be used for:

• Office partitions and meeting rooms

• Doors and bathroom glass

• Hotel and residential interiors

• Curtain walls and exterior glazing

• Skylights and other daylight-control applications

For exterior projects, the complete glass structure should be designed according to safety, structural, thermal, weather and local building-code requirements.

Which Smart Glass Should You Choose?

In short, smart glass is not a single technology. 

The right solution depends on whether your project needs privacy, solar control, glare reduction, or a combination of functions.
