Insulation is a barrier that minimizes the transfer of heat energy from one material to another by reducing the conduction, convection and/or radiation effects, Derived by application of Heat transfer between objects of differing temperature. This means to stem the heat Flow by specially engineered methods or processes. Heat flow is an inevitable consequence of contact between objects of differing temperature. Thermal insulation provides a means to maintain a gradient of temperature, by providing a region of insulation in which heat flow is reduced or thermal radiation is reflected rather than absorbed.In building construction, insulating materials are assigned a quantitative measure of the insulating capability, called the R-value. In thermal engineering of insulating systems for ovens, reactors, and furnaces, thermal conductivity (K), product density and specific heat (C ) are the key product characteristics, which influence insulating efficiency, such as accolade insulating. Flow thermal conductivity (K) is analogous to high insulating capability (R).Thermal insulation is a versatile term but principally covers the subject of control the loss of heat energy. This energy loss can be controlled with the help of naturally available minerals processed to suit a particular application. The minerals are Glass, Ceramic and Silica. Various forms of above materials are manipulated / processed and treated with synthetic /organic additives or coating helps the materials to perform in most critical applications.
