The Technology behind

‘Cool’ Roofs

specialized pigmentsPigments are

colored powdersIncorporated into paint,

plastics, concrete, ceramics…

Applied on or formed into

various materials

Imparting a wide range of colored

Providing Lasting Color for Premium Products

Ceramic chemistry = ‘Tough’

Kiln-fired at temperatures exceeding 1000 ºC, Arctic pigments are essentially

synthetic minerals

Oxide raw materials are fused into a single crystalline color

Ceramic chemistry = ‘Tough’

This chemical structure provides the ultimate resistance to sunlight, chemicals, and heat

How do Arctic Pigments make possible Cool Roofing materials?

well, it all starts with the Sun…

Roof

Sunlight is dissipated in four ways when encountering the

surface of a roof

Roof

Conduction: Heat transferred

into building

Sunlight

Reflection1. Reflection2. Conduction3. Emission4. Convection

Convection: Heat transferred to air in and around building

Emission: Heat radiated

as long wavelength IR

Roof

Sunlight

Conduction and Convection draw heat from the Sun into the building or home, increasing cooling costs.

How do Arctic Pigments increase reflection without sacrificing color?

By selectively reflecting infrared light!

Arctic Pigments help reflect the sun’s energy away from our cities!

Our cities are growing hotter, as seen in these satellite photos.
