To choose the best type of insulation, you should first determine the following: The recommended R-values for areas you want to insulate. The maximum thermal performance or R-value of insulation is very dependent on proper installation.
Insulation decreases the amount of heat entering from outside when its hot and traps warmth inside when its cold. Insulation is rated by its R-value. R-value measures how resistant types of insulation is based on the type, thickness and density of the insulation material.

Insulation is any material that can reduce heat transfer. Options for home and commercial buildings include recycled denim, cork, fiberglass, cellulose, foam, mineral wool, cotton, straw, and sheep's wool.
