Types of Insulation

As insulation contractors in the Twin Cities, we are often asked about the types of insulation we install. Here is a rundown of three of them so you can learn the advantages and benefits of each one.


Fiberglass insulation is made of sand and recycled glass, and it is one of the most popular types of material used by insulation contractors today. Because it’s non-combustible, non-absorbent and non-corrosive, it is a great choice for a wide variety of homes. It can be installed in a variety of rooms too: from crawl spaces to garages. It is an excellent sound barrier, and it only settles slightly. This type of insulation helps maximize your home’s energy efficiency, plus it can help to reduce unwanted noise and improve your home’s indoor air quality.

Spray Foam

Spray foam insulation is a great long-term investment. Insulation contractors like it because it will help homeowners save up to 50% on heating and cooling savings, which is a pretty significant amount! Your furnace and air conditioner will thank you because this type of insulation means your HVAC equipment will not need to work as hard to heat and cool your home. Spray foam insulation also can reduce the amount of pollutants and allergens that can enter your home and can protect against mold and animals that like to nest and live in your home.


This is the most eco-friendly option insulation contractors can use since it’s made up of about 75% recycled material. Cellulose can help prevent the upward movement of air that is caused by differences in temperature. It is also non-corrosive to steel, aluminum and copper, and it will not mildew, rot or decay, nor will it allow mold or other fungus to grow.
