Thermal insulation is the reduction of the heat transfer between objects in thermal contact area. The act of insulation
is accomplished by encasing an object in material with low thermal conductivity. Thermal insulation provides a region of
insulation in which thermal conduction is reduced. Low thermal conductivity is equivalent to high insulating capability. Thermal
insulation is mainly used in where the heat transfer rate is high. Thermal industries generally use cotton ropes, mineral wool,
glass wool, polyethylene, saw dust as insulators etc
