SPD SmartGlass is a dynamically variable, instantly reactive glazing technology that changes from soft blue to a dark blue tint to give you the ability to "tune" the amount of light and sunglare streaming through a window or skylight. The tint level is infinitely adjustable - as opposed to simply ON/OFF - and it has a very wide dynamic light transmission range (can block out over 99.5% of Light Transmission in its off state). This allows you to instantly control the heat gain and view quickly and effectively.
