1 The Technology behind ‘Cool’ Roofs

2 specialized pigments Pigments are colored powders Incorporated into paint, plastics, concrete, ceramics… Applied on or formed into various materials Imparting a wide range of colored effects…

3 Providing Lasting Color for Premium Products

4 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

5 Ceramic chemistry = ‘Tough’ This chemical structure provides the ultimate resistance to sunlight, chemicals, and heat as demonstrated by…

6 Three Decades of Proven performance in South Florida

7 How do Arctic Pigments make possible Cool Roofing materials? well, it all starts with the Sun…

8 Roof Sunlight is dissipated in four ways when encountering the surface of a roof

9 Roof Conduction: Heat transferred into building Sunlight Reflection 1. Reflection 2. Conduction 3. Emission 4. Convection Convection : Heat transferred to air in and around building Emission : Heat radiated as long wavelength IR

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

11 Roof Sunlight Conduction and Convection draw heat from the Sun into the building or home, increasing cooling costs. pigments minimize conduction and convection, by Increasing Reflection! Conduction Reflection Convection

12 Roof Sunlight Conduction Reflection Convection Conduction and Convection draw heat from the Sun into the building or home, increasing cooling costs. pigments minimize conduction and convection, by Increasing Reflection!

13 How do Arctic Pigments increase reflection without sacrificing color? By selectively reflecting infrared light!

14 Of the Sunlight that reaches the Earth… VisibleVisible nm Infrared nm UV < 400nm 4% 46%50% …only 46% is Visible to the human eye. Color This 46% is responsible for a Roof’s Color. Solar Spectrum

15 UV 4% Visible 46% IR 50% Sunlight nm Roof Conventional pigments, used to make dark colors, reflect little energy in the invisible Infrared region.

16 Sunlight UV Visible IR Dark Color Low IR Reflectance High Heat Build-up Roof Hot Roof !!! Conventional pigments, used to make dark colors, reflect little energy in the invisible Infrared region.

17 Sunlight Roof Dark Colors, which absorb the sun’s energy in the visible region, can be cool… UV Visible IR

18 Sunlight Roof Dark Colors, which absorb the sun’s energy in the visible region, can be cool… …IF they reflect the sun’s energy in the infrared region. UV Visible IR

19 Sunlight Dark Color High IR Reflectance Low Heat Build-up Roof Dark Colors, which absorb the sun’s energy in the visible region, can be cool… Cooler Roof !!! …IF they reflect the sun’s energy in the infrared region. UV Visible IR

20 The same visible color: The Arctic formulation reflects the infrared light, which makes the surface (and interior spaces) cooler. Can look very different to an infrared camera: StandardArctic By using

21 Energy avings!! The Net Result? $ $ $ $ $ $ $ $ $ $

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

23 Our cities are growing hotter, as seen in these satellite photos. Atlanta from space (darker is hotter) This phenomenon is known as Urban Heat Island

24 Roof Sunlight Convection and Emission warm the surrounding air, day and night, from heat stored in the roof. Reflection Convection Emission

25 Roof Sunlight Convection and Emission warm the surrounding air, day and night, from heat stored in the roof. pigments minimize convection and emission by Increasing Reflection! Reflection Convection Emission

26 Roof Sunlight Reflection Convection Convection and Emission warm the surrounding air, day and night, from heat stored in the roof. pigments minimize convection and emission by Increasing Reflection! Emission

27 The Net Result? Clean Air & Quality of Life!!
