solarsmartPALRAM'S SOLARSMART™ TECHNOLOGY defies standard transmission of solar energy in transparent sheets and allows more versatile color and solar transmission specification per project. Unlike regular tints, SolarSmart sheets and panels admit more natural daylight while reflecting outwards Infrared radiation that creates heat. This characteristic breaks the traditional link between shading coefficient and light transmission, allowing a different perspective on the specification of natural light in architectural design.

Near-Infrared Selectivity

The efficiency of SolarSmart products is measured by their ability to better differentiate between visible light and Near-Infrared energy transmission. Near-Infrared Selectivity values are is calculated by dividing the levels of visible light (400 to 750nm) and Near-Infrared radiation (750 to 1400 nm). Example values of Near-Infrared selectivity appear in each SolarSmart™ group page.

Efficiency Comparison

The attached graph demonstrates the efficiency of SolarSmart products in comparison with clear and standard colored sheets. The graph shows how SolarSmart tints enable higher light transmission specification while maintaining or decreasing shading coefficient values.
