Thermal insulation is the inhibition of heat transfer from one object to another differing in temperature and which is in thermal contact with it.
There are many situations in which it is desirable to reduce heat transfer in a certain direction, the most common case being the insulation of buildings with the aim of minimizing heat losses in winter and gains in summer.
However, other industrial products in which it is necessary to improve the efficiency in its consumption and security should not be overlooked.
Some examples are distribution pipes for hot or cold liquids, heat exchangers or boilers where the efficiency in its consumption is a must. Also, thermal insulation is crucial for specific packaging in the food-industry and food delivery.
With the environmental pressures that blight the world nowadays, insulation is becoming more and more important as it is a linchpin of the reduction of the energy obtained from fossil fuels and, consequently, a downsizing of CO2 emissions to the atmosphere.
