Insulation is one of the best ways you can save money on your energy bills. Insulation’s main purpose is to stop heat loss and keep the cold air outside. One of the main factors of how low your energy bills will be is in direct relation to how much heat you can keep in your house. The R-value is how this is measured.

What is R-value?

When anyone talks about insulation, weather it is blown in or rolled insulation everyone refers to the R-value. The R-value is the amount of heat that can pass through the layer of insulation. How resistant to heat is the insulation? The higher the R-value or thicker the insulation, the harder it is for heat to get through it or escape your home. To recap; the more insulation you have, the greater R-value you will have causing more heat to stay in your home and your furnace will not be running all the time, saving you more money.

What are the different types of Insulation?

Fiberglass insulation is one type. There are two types of fiberglass insulation: fiberglass loose-fill insulation, which is blown in, and fiberglass rolled insulation, which comes in pieces or rolls and in different thicknesses. Fiberglass is made up of sand and glass.

Cellulose is another type of insulation. It’s mostly made of paper, which makes it combustible. Although cellulose insulation is treated with fire retardant, it isn’t fireproof. Cellulose insulation takes 3 times as much as fiberglass insulation to do the same job. Cellulose settles quicker and at a faster rate than other types of insulation. For insulation to work properly it must be light and fluffy. If insulation is moist and matted down, then it will not be as effective.
