The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer. Heat energy can be transferred by conduction, convection, radiation or by actual movement of material from one location to another. For the purposes of this discussion only the first three mechanisms need to be considered. Thermal insulation is the method of preventing heat from escaping a container or from entering the container. In other words, thermal insulation can keep an enclosed area such as a building warm, or it can keep the inside of a container cold. Heat is transferred from one material to another by conduction, convection and/or radiation. Insulators are used to minimize that transfer of heat energy. In home insulation, the R-value is an indication of how well a material insulates. The flow of heat can be reduced by addressing one or more of these mechanisms and is dependent on the physical properties of the material employed to do this.

Q. explain how insulation between the outer and inner walls of a home helps to reduce thermal energy transfer.? Asked by bob - Sun May 20 12:18:20 2007 - - 2 Answers - 0 Comments A. ___ Thermal energy (Q) transfer by conduction depends on (i) temperature difference [To -Ti ] across the outer and inner walls. (ii)Distance between the walls 'l' (iii) area of wall 'A' (iv) nature of material [ called thermal conductivity 'K' ]of walls Q = KA[To-Ti] / l An insulator has very poor conductivity, 'K' for insulator is small Hence insulation prevents the transfer of heat across the walls.Insulation reduces heat leakage in a home ___ Answered by ukmudgal - Sun May 20 12:37:08 2007 From Yahoo Answer Search: "thermal insulation"  video.google.com Wed, 18 Jan 2006 15:05:02 PST bale house from start to finish.
