SPD Variable Tint Glass

The SPD (Suspended Particle Devices) Variable Tint Glass regulates the light, heat and glare that passes through it.

Powered by 110VAC but uses a low DC current, the SPD glass varies from light to dark blue tint. When turned OFF, the SPD glass returns to a dark blue tint.

Aside from shielding 99% of UV rays which are harmful to furniture and artwork, the SPD Variable tint also rejects solar heat creating a cooler temperature inside the room.

Benefits of Using SPD glass

Sustainable Architectural Design – increase the energy efficiency of buildings, improve the well-being of occupants, and lower the environmental impact of buildings and structures.

Daylight harvesting – reduce the need for artificial lighting by creating designs that use natural light for illumination. A reduction in internal electrical lighting needs show a potential annual savings of 35% - 60% on lighting energy.

Eliminate window coverings and maintenance costs – SPD provides partial privacy (depending on its tint level) while constantly providing you with the "View".

Block UV Rays - SPD smart glass blocks almost 99% of UV rays thus help in the preservation of artwork and furniture.

Energy Saving– SPD glass panels provide excellent control over solar heat (see SHGC table), reducing internal lighting needs which translate to lower HVAC sizing and energy bills.

Provide the WOW factor.
