SPD Smart Glass (Dynamic Solar Control)
Dynamic regulation of daylight, glare, and solar heat for architectural facades, luxury yachts, and transportation.
DYNAMIC SOLAR & THERMAL CONTROL ON DEMAND
ADPI's SPD (Suspended Particle Device) Smart Glass revolutionizes glazed building envelopes. It modulates solar radiation and thermal heat transfer in real time, eliminating glare while preserving clear, unobstructed panoramic views of the outside world.
Solar & Thermal Heat Control
Blocks up to 99.5% of solar radiation and visible light, drastically reducing interior solar heat gain and HVAC cooling expenses.
Continuous Variable Shading (Dimming)
Smooth transition and tunable shading. Not restricted to a binary ON/OFF state: fine-tune any intermediate tinting level to match changing sunlight intensity.
Total UV & Infrared Protection
Continuous blockage of over 99% of harmful ultraviolet and infrared rays in every state, protecting occupants and preventing fabric and furniture fading.
Sunglasses Effect (Preserved Views)
Unlike PDLC which switches to frosted white for privacy, SPD darkens with a sophisticated deep blue tint while preserving crisp, clear outward views.
Energy Efficiency & Sustainability
Lowers building thermal cooling load by up to 40%, slashing air-conditioning consumption and supporting LEED, BREEAM, and WELL building certifications.
Engineered Durability & Longevity
High molecular stability nanoparticle film tested to withstand over 100,000 hours of continuous direct solar exposure and severe thermal cycling.
HOW SPD SMART GLASS WORKS
Suspended Particle Device (SPD) technology enables custom, on-demand glass tinting. In its natural unpowered state (0V), microscopic particles absorb light, blocking up to 99.5% of visible radiation. When voltage is applied, particles align to let light through, providing crystal-clear outward views while substantially reducing HVAC cooling costs.
- Natural Unpowered State (0V): In the absence of applied voltage, microscopic suspended particles disperse randomly via spontaneous Brownian thermal motion.
- Solar Radiation & Light Absorption: In their chaotic orientation, suspended particles intercept and absorb photons, achieving up to 99.5% blockage of visible light and solar heat.
- Thermal Comfort Without Mechanical Blinds: Keeps interiors cool and protected from harsh glare, performing like high-performance polarized architectural sunglasses.
- Dipolar Alignment via Electric Field: The applied AC electrical field forces suspended nanoparticles to immediately align perpendicularly in parallel with light rays.
- Clear Vision & Natural Daylight: Daylight passes directly through the glass with up to 50% visible light transmission (VLT), providing crystal-clear outward views.
- Variable Shading (Continuous Dimming): By modulating the applied AC voltage up to 100V, the exact level of daylight tinting is tuned in real time with absolute precision.

SPD SOLAR CONTROL GLASS SPECIFICATIONS
Certified parameters verified under European and international building energy efficiency, automotive, and marine standards.
Light & Solar Heat Blockage
Blocks up to 99.5% of visible light, eliminating exterior glare and drastically reducing solar heat gain (SHGC) to maintain indoor comfort without blinds.
Transmission Range (VLT)
Controlled continuous dimming that enables light transmission ranging from under 0.5% in deep dark tint to 50% in clear transparent state.
UV & Infrared Radiation Blockage
Continuous filtration of damaging ultraviolet radiation and infrared thermal heat across all tint levels, preventing upholstery and interior fading.
Certified Applications
Architectural facades, skylights, luxury superyachts, high-speed rail transit, and automotive panoramic roofs.
Energy Consumption
Maximum consumption of <5 W/m² exclusively in active clear mode. In unpowered rest state (protective dark tint), energy consumption is 0 W.
Modulated Operating Voltage
Powered via specialized ADPI electronic controllers operating at 100V AC square wave for smooth, silent, and reliable dimming.
Operating Temperature Range
Engineered specifically for exterior building envelopes subjected to intense solar radiation, frost, and extreme thermal swings.
Certified Operational Lifespan
Accelerated weathering tests demonstrate over 25 years of uninterrupted architectural performance with zero tonal degradation.
