SPECTURALLY SELECTIVE
IQue™ Spectrally Selective films are the perfect way to match light visibility and heat control to the unique configuration of your home or workspace. Spectrally Selective films offer options for greater flexibility in addressing your need to control solar heat, glare and transmission of visible light .
The IQue™ 73FG film, originally developed for the US space and military program and now adapted for commercial use, features a 94% rejection of infra-red and a 99% rejection of ultra-violet spectrum while allowing 70% of visible light transmission. This makes it ideal for areas that require a high amount of clarity while preventing the least amount of heat to penetrate the interior.
Among the many commercial applications of 73FG are retail outlets, penthouses, atria and air control towers, essentially places where optimal heat rejection and maximum clarity is required.

The IQue 78FG film is a full-fledged Spectrally Selective coating with good solar heat rejection properties and yet still offers an amazingly clear view. The key advantage that 78FG offers is its high visible/ natural light transmission which most architects prefer for architectural applications. Applications for 78FG include windows for retail shop fronts, restaurants, art galleries and residential units where very high light transmission is required.
