Thermally responsive SPD products automatically adjust their tint based on ambient temperature changes, offering passive operation without requiring electrical input.

Market Insight: This segment currently represents 22% of the market and is growing at a healthy 9.7% CAGR. It’s particularly popular in skylight and sunroom applications where passive operation is desired.
Trend: Recent developments allow for hybrid thermal-electric operation, enabling both automatic response and manual override capability.

3. Liquid Crystal SPD Glass

LC-SPD variants combine liquid crystal and suspended particle technologies to offer enhanced clarity in the clear state and superior opacity in the tinted state.

Market Insight: With 13% market share, this segment is the fastest-growing, projected to expand at 14.2% CAGR through 2029. Its adoption is being driven by premium automotive and luxury residential applications.
Trend: Automotive manufacturers are increasingly specifying LC-SPD for sunroof applications where perfect clarity is essential when untinted.

4. Smart Laminated SPD Glass

Advanced laminated versions incorporate additional functionalities such as sound dampening, UV blocking, and structural reinforcement.

Market Insight: These premium products command higher margins but represent only 7% of unit sales, primarily serving the high-end architectural market.
Trend: Integration of smart laminated SPD glass with building automation systems is creating new opportunities in commercial construction projects.
