Engineering Specification for Thermal Insulation Hot.Method of Specifying Thermal Insulating Materials on Pipes, Ductwork and Equipment BS 5422 (In the temperature range -40 ☌ to +700 ☌)ġ.2.2 Engineering specification - Cold Thermal Insulation Specification. ![]() Code of Practice for Thermal Insulation of Pipe Work and Equipment BS 5970 (In the temperature range –100 ☌ to +870 ☌).Unfaced Preformed Rigid Cellular Polyurethane Thermal Insulation ASTM C 591.– It must be installed without gaps, voids, compressions, and low spotsįor more information about insulation, see the U.S. – The proper insulation must be selected for the appropriate application The higher the R-value per inch, the better the insulating performance. To compare the insulating quality of insulations, look for the “R-value per inch.” The R-value relates to the resistance the material has to the flow of heat. In cold climate, it keeps the heat in your home from leaking out (making your home feel warmer and causing your heating system to run less). However, spun glass, or glassfiber, is a good insulator because it creates millions of tiny air pockets between the tiny pieces of glass that slow the movement of heat. As an example, one of the most common insulating materials, fiberglass, is made from spun glass, and the actual material has very little ability to slow heat transfer. There are many types and forms of insulation, and some are better than others at insulating however, all work by using dead air spaces or cells to slow heat flow. ![]() The result in both climates is energy saved by keeping the air conditioner or the furnace from operating as often. Since heat will always move to a colder source, in cold climates, insulation slows the heat from leaving the house and in hot climates insulation slows down the hot outside air from entering the cool inside. Insulation doesn’t “heat” an area, it simply slows down heat movement through building materials.
