Development and Application of Near Infrared Reflective Pigments in 1 Part Cementious Decking Materials
Alvin Sherman Library 1054
New Techniques in the preparation of certain pigments used in the colorant industry have revealed a natural Near Infrared, NIR, reflectivity. The use of these pigments as colorants increases the reflection of radiation in the NIR that dramatically decreases the surface temperature of the materials when exposed to solar radiation. Traditionally, colored decking materials usually resulted in the deck reaching feet burning temperatures in the southern tier of the United States, (Florida to California). While white decks are cooler, the reflectivity in the visible region results in glare and creates a stark appearance to the pool deck. The reduction in absorbance of NIR radiation using these pigments is presented. Applications of these pigments in other construction materials and the energy reduction that result are also discussed.
