Insulation

To understand however insulation works it helps to grasp heat flow, that involves 3 basic mechanisms conductivity, convection, and radiation. conductivity is that the means heat moves through materials, like once a spoon placed in an exceedingly hot cup of occasional conducts heat through its handle to your hand. Convection is that the means heat circulates through liquids and gases, and is why lighter, hotter air rises, and cooler, denser air sinks in your home. refulgent heat travels in an exceedingly line and heats something solid in its path that absorbs its energy.

Most common insulation materials work by fastness conductive heat flow and–to a lesser extent–convective heat flow.refulgent barriers and reflective insulation systems work by reducing refulgent heat gain. To be effective, the reflective surface should face associate degree air house.

Regardless of the mechanism, heat flows from hotter to cooler till there’s not a temperature distinction. In your home, this suggests that in winter, heat flows directly from all heated living areas to adjacent cold attics, garages, basements, and even to the outside. Heat flow may move indirectly through interior ceilings, walls, and floors–wherever there’s a distinction in temperature. throughout the cooling season, heat flows from the outside to the inside of a house.

To maintain comfort, the warmth lost within the winter should get replaced by your heating and therefore the heat gained within the summer should be removed by your cooling system. Properly insulating your home can decrease this heat flow by providing an efficient resistance to the flow of warmth.
