Palram SolarSmart™ Technology

Efficient Daylighting with High light transmission and Heat Blocking

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.

Promoting Energetic Efficiency and Well Being

SolarSmart tints allow better use of natural lighting without
sacrificing the interiors. More natural light results in a
healthier and more productive ambience. Energy saving is
also promoted through reduction of both illumination and
air conditioning requirements.

Promoting Energetic Efficiency and Well Being

The Solar Spectrum

250nm – 400nm 400nm – 750nm 750nm – 1,450nm
Ultra-Violet
Harmful to living tissue and may causes skin cancer. All Palram polycarbonate products block 99.9% of UV radiation.
Visible Light
Visible light enables eyesight, whereas natural daylight also promotes well-being. Palram offers tailoring of specific light transmission and diffusion for any given project.
Near-Infrared
Converts to heat when absorbed by objects, resulting in heat buildup. SolarSmart products block a portion of the Infrared radiation and transmit “cool light”, thus improving well being while reducing AC costs.

SOLARSMART EFFICIENCY COMPARISON

The graph on the right 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.

NEAR-INFRARED SELECTIVITY

From a materials perspective, SolarSmart™ sheets are measured by their ability to differentiate between visible light and near-infrared energy. This is calculated by dividing the levels of visible light (400 to 700nm) and near-infrared radiation (750 to 1400 nm). Example values of near-infrared sensitivity appear in each SolarSmart™ group page. Higher value is better.
