NanoEC™ SPU™ is an integrated smart glass technology that allow passengers to shade their windows on-demand from 50% down to 3% light transmission.

Developed by Heliotrope Technologies, the NanoEC™ SPU™ product can be easily integrated in a standard IGU as either the outboard or inboard lite depending on desired solar/thermal performance. As a result, the need for manual shades/blinds is removed along with providing an enhanced experience for the passenger through comfort and unobscured views of the exterior landscape. Operators benefit from potential reductions in maintenance, operation, and installation costs with a weight neutral solution. NanoEC™ SPU™ can also be easily integrated into the growing trend of information systems for on-board and off-board applications, real time passenger information, entertainment and commercial advertisements.
