Insulation stores the heat produced by the body and lets the body’s mechanism of heat-making maintain the body’s proper temperature. The loss of body heat is due to heat conductance. Heat is always attracted toward the cold to equalize two objects temperature. Insulation stops the heat by getting conducted. The vacuum is the right insulation and close to it is dead air. When air does not move, the heat is not able to pass it. Foam insulation is also very efficient but also there are many different kinds of insulation like Heat Insulation, Home Insulation, Cavity Wall Insulation, Pipe Insulation, Fiberglass Insulation etc.
The vacuum bottle is an example of vacuum that works as an insulator. The beverages are stored in the vacuum bottle, to keep cold things cold and hot things hot. You require it for hot things at the air outside is cooler than coffee, and the coffee heat might leak into the surrounding cool air. You require it for cold things as the air outside are hotter than the lemon squash, and the air heat passes into the lemonade and thus ice cubes melt down. With a vacuum in the vacuum bottle, the heat is kept out for the lemonade and in for the coffee.
Long time back people saw that geese and ducks were able to stay comfortable and were also able to swim in cold water without any suffering. While picking the waterfowl before cooking it, the secret was revealed: goose down and fluffy duck. When they packed this between their clothing layers, they could maintain the body temperature as warm as the geese and ducks’ bodies. Sometimes they discovered how it works. The down is not tightly packed and stays fluffy, and throughout there are air pockets that contain dead air, which, keeps the warmth of the body in and the chilly winter out.
Let us shift from small to big; the next thing to be kept comfortably warm is our home. The applications of vacuum and down are not practical here, but there are different kinds of materials like Cavity Wall Insulation, Pipe Insulation, and Fiberglass Insulation etc. that are used for heat insulation. They function in a similar fashion as the down, with countless dead air pockets. One of the widely used types of insulation is made from fibers of fiberglass. It is generally laid out on the attic floor. As the heat rises up, it goes toward the room ceilings in the rooms and is blocked by the pockets of air in fiberglass. Foam is ideal heat insulation.
