Understanding Heat Insulation

Winter is like an enemy. We require warmth to keep our limbs working. Our physical body generates a great amount of heat, but if the winter is too cold, the heat-making power of our body cannot fight the cold’s attack; the water of our body freezes, and so our body can also die. An active heat source like fire can prevent this cold. And if this source is not available, the best option for of defense is insulation or passive heat.

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.
