One of the main benefit of a thermal insulation coating is to lessen the amount of heat in a building or house. We have been talking about thermal insulation in our previous posts but a lot of people is still not familiar with this concept. So let’s dig deeper for us to get a better understanding on how this helps any structure coated with thermal solution blocks sunlight and lower energy consumption. A thermal insulator is something that prevents heat from moving from one place to another which can travel in three ways: conduction, convection, and radiation. Typically the phrase thermal insulator refers to a material that blocks conduction.
Conduction is what happens when something hot physically touches something cold. Heat molecules moves from the hot to the cold surface making it warm. Using a thermal insulator or a material where heat molecules cannot easily travel into can significantly lessen the amount of heat. Glass, plastic, rubber, porcelain, and wood are common insulators you’ll see around the household.
The important thing to remember to reduce thermal conduction is to minimize the movement of thermal energy. One of the most obvious thermal conductors are metals like our roof that is why most structures have ceilings that also help in lowering the room temperature. Thermal conductivity is air is low, but they are prone to thermal convection which means big currents of flowing material like dusts and vapor carry the heat around. Blankets made up of cloth fibers can partially stop convection.
Understanding insulation helps you identify poor energy performance. An in-depth knowledge about thermal insulation will also help you understand what makes it malfunction and contribute to saving energy in your workplace or home. Slowing the transfer of heat is just as important in hot weather as it is during cold weather. So just like how a jacket keep you warm during the winter, the same principles apply when it’s hot outside and you want to save money on air conditioning and refrigeration.
