When it comes to insulating your home or business, it’s important to choose the right material. Two popular options are cellulose and fiberglass insulation. While both have their pros and cons, one may be better for your specific needs. In this article, we’ll explore the differences between cellulose and fiberglass insulation to help you make an informed decision.

What is Cellulose Insulation?

Cellulose insulation is made from recycled paper products, such as newspapers, that have been treated with chemicals to make them fire-resistant. It’s an eco-friendly option that’s safe for humans and animals. Cellulose insulation is blown into walls, attics, and other areas using a special machine.

Pros of Cellulose Insulation

One of the biggest advantages of cellulose insulation is its high R-value, which measures how well it resists heat flow. This means that cellulose insulation is very effective at keeping your home warm in the winter and cool in the summer. Additionally, cellulose insulation is more resistant to air leaks than fiberglass insulation, which can help reduce your energy bills.

Cons of Cellulose Insulation

One potential drawback of cellulose insulation is that it can settle over time, which may reduce its effectiveness. Additionally, cellulose insulation can be more expensive than fiberglass insulation, especially if you need to hire a professional to install it.

What is Fiberglass Insulation?

Fiberglass insulation is made from tiny glass fibers that are spun into a material resembling wool. It’s widely used in homes and businesses because it’s affordable and easy to install. Fiberglass insulation can be installed as loose fill or batts, which are pre-cut pieces that fit between wall studs and ceiling joists.

Pros of Fiberglass Insulation

One of the biggest advantages of fiberglass insulation is its low cost. It’s also easy to install, which means you can do it yourself and save even more money. Additionally, fiberglass insulation doesn’t settle over time, which means it will maintain its effectiveness for years to come.

Cons of Fiberglass Insulation

One potential drawback of fiberglass insulation is that it can be irritating to the skin, eyes, and lungs if it’s not installed properly. Additionally, fiberglass insulation is not as effective at reducing air leaks as cellulose insulation, which can lead to higher energy bills.


When deciding between cellulose and fiberglass insulation, it’s important to consider your specific needs and budget. If you’re looking for an eco-friendly option that’s effective at reducing air leaks, cellulose insulation may be the way to go. However, if you’re on a tight budget and want an easy-to-install option, fiberglass insulation may be the better choice. Ultimately, the decision is up to you.
