Insulation r-value is a grade that shows how well the insulant will curb heat-transfer. This is how much heat can pass through a home’s ceiling. The higher the r-value per inch an insulant has, the more it will help to regulate your home’s internal climate. As you raise the r-value of your home’s attic and walls you will see a drop in your utility bills.
To put it simply insulants create a wall between your home’s internal climate and the climate of the space around your home. When the heat is high and the air is humid, the right insulation system will keep the moisture from coming into your home and it will keep the heat at bay as well. This means that your AC will not have to run for as long or as often to keep your home pleasant. When it is at its coldest outside, you can trust your insulation to keep the heat your furnace has produced from leaking out of your home.
This grade can be used to find out what kind of insulant to use in your attic, as well as how much of it you need. In the state of Michigan, it is advised that your attic have enough insulant to produce an r-value of 49-60 and your exterior walls have an r-value of 21.
