Insulating Your Attic: 4 Types of Insulation Explained

When it comes to insulating your attic, there are a few different options to choose from. The most common types of attic insulation are fiberglass block, blown fiberglass, cellulose, and spray foam. Each type of insulation has its own advantages and disadvantages, so it's important to understand the differences before making a decision.

Fiberglass Block Insulation

Fiberglass block insulation is the most common type of attic insulation.

It is made from small pieces of glass that are held together with a binder. The advantages of this type of insulation include its affordability and ease of installation. However, it can be difficult to install in tight spaces and can be prone to settling over time.

Blown Fiberglass Insulation

Blown fiberglass insulation is another popular option for attics.

This type of insulation is made from small pieces of glass that are blown into the attic space using a machine. The benefits of blown fiberglass include its ability to fill in any gaps or cracks in the attic, as well as its resistance to settling over time. However, it can be more expensive than other types of insulation and requires two people to install it properly.

Cellulose Insulation

Cellulose insulation is made from recycled paper products and is often used in attics.

It is usually blown into the attic space using a machine and can be used to fill in any gaps or cracks in the attic. The advantages of cellulose insulation include its affordability and ease of installation. However, it can be more difficult to install in tight spaces and can be prone to settling over time.

Spray Foam Insulation

The last type of attic insulation is spray foam insulation.

This is becoming increasingly popular as time goes on, probably because of its extensive benefits. Unlike all other types of attic insulation, spray foam insulation is the only one that comes in liquid form. It is sprayed into the attic space using a machine and can be used to fill in any gaps or cracks in the attic. The advantages of spray foam include its ability to fill in any gaps or cracks in the attic, as well as its resistance to settling over time.

Making the Right Choice

When deciding which type of attic insulation is right for you, it's important to consider your budget, the space you have in the attic, and whether you plan to insulate the attic yourself or hire a professional. Adding certain types of insulation to the attic is also a cost-effective home improvement, offering an average return on investment of 117% in the form of an increase in home value. Sufficient and properly installed attic insulation can help the roof last longer (because it helps prevent ice accumulations from accumulating) and even reduce excess outside noise that helps you sleep. You can save an average of 15% on your heating and cooling costs by simply sealing your home with air and adding insulation to strategic areas like your attic.

In conclusion, there are four main types of attic insulation: fiberglass block, blown fiberglass, cellulose, and spray foam. Each type has its own advantages and disadvantages, so it's important to consider your budget, the space you have in the attic, and whether you plan to insulate the attic yourself or hire a professional before making a decision.
