How the cellulose insulation will affect heating and cooling?

Explanation:

The use of cellulose insulation slows the transmission of cold and heat. It is more efficient than batt insulation at preventing thermal transfer. It fills holes and prevents them from forming. It keeps an even temperature in your home by preventing thermal transfer by surrounding joints and beams.

Answer :

Insulation reduces the exchange of heat through a surface such as a wall, attic, duct or roof. In a well-insulated home, less warm air escapes from the house during the winter, and less cool air escapes during the summer, reducing the amount of energy needed for heating and cooling.

Insulation means creating a barrier between the hot and the cold object that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one object to the other. Depending on the material of the barrier, the insulation will be more or less effective.
