![]() ![]() Thermal insulating coating (n): a liquid or semi-liquid, suitable for application to a surface in a thickness of 30 mils (0.75 mm) or less per coat, that dries or cures to simultaneously form a protective finish and provide resistance to heat flow Thermal insulation (n): a material or assembly of materials used to provide resistance to heat flowįurther on in C168 is the following definition for coating:Ĭoating (n): a liquid or semi-liquid that dries or cures to form a protective finish, suitable for application to thermal insulation or other surfaces in thickness of 30 mils (0.76 mm) or less, per coatĬombining these two definitions-allowing that a “thermal insulating coating” does not have to cover thermal insulation but can act as thermal insulation alone-yields a proposed definition for a TIC: While ASTM does not have a definition for “thermal insulating coating,” ASTM C168 (the standard for insulation terminology) includes the following definition for thermal insulation: One typically reliable source for definitions like this is the American Society for Testing and Materials (ASTM). That may be true, but a temperature differential can be produced by almost any a material that has some thickness and thermal conductivity-and not all of those materials would necessarily be considered thermal insulation. One TIC manufacturer defines them as follows: “A true insulating coating is one that produces temperature differentials across its surface, no matter where the coating is placed (i.e., to the hot/cold surface or inside or outside).” I first heard of them about 10 years ago, and they have been commercially available longer than that. If energy costs remain high, or even increase, that interest is likely to grow. In looking for cost efficiencies, there is growing interest in the use of thermal insulating coatings (TICs). Further, facility owners are under pressure to do so in ways that reduce craft labor hours or use lower-cost craft labor. With today’s high energy prices and improving markets for mechanical insulation products, design engineers and facility owners have greater interest in reducing energy consumption by increasing energy efficiency.
