Finite element method is mainly applied in continuous mechanics, thermal conducting, electromagnetism field and so on. Its basic thought is that consider district as limited and conterminous units with certain rule, then combine system square and solve it. The fly ash-foam heat insulating material is a kind of inorganic -organic compound, containing more micron and sub-micron class pore structure and a great deal of hollow tiny bead. The mechanism of heat transmission is very complicated. Therefore, finding the mechanism of heat transmission will contribute to understanding the material how to keep temperature. It is instructive to enhance the performance of the material. In this paper, the thermal module of Finite element analysis is used to simulate the course of heat transmission of the fly ash-foam material. It shows that the result of simulation and measured value are accordant.
