Insulation is essential for maintaining a comfortable and energy-efficient home. The attic is one of the most critical areas where proper insulation is crucial. Properly insulating your attic can save you up to 20% on your energy bills.

Various types of insulation are available on the market, each with unique properties and benefits. In this article, we'll discuss the four most common types of attic insulation. Read on to help you make an informed decision for your home.

1. Fiberglass Insulation

Fiberglass insulation is the most common type of attic insulation and has been used for decades. It consists of tiny glass fibers that trap air pockets. You can buy them in rolls, batts, or blown-in form.

Here are some pros:

• affordable

• widely available

• lightweight

• easy to install

• excellent thermal resistance

However, there are some cons:

• can irritate the skin and lungs

• can settle over time

• not the best for tight spaces

• can lose effectiveness when wet

2. Cellulose Insulation

Cellulose insulation is made from recycled materials such as newspapers and cardboard. It's an environmentally friendly option and is often blown in to fill in small gaps and crevices.

Here are some pros:

• eco-friendly

• effective at reducing air infiltration

• good for hard-to-reach areas

• resistant to pests

• can be added on top of existing insulation

However, there are also cons:

• more expensive than fiberglass

• can settle over time

• not fire-resistant

• can mold if wet

• can be a breeding ground for insects

3. Spray Foam Insulation

Spray foam insulation is a newer type of insulation. It's made of polyurethane and is applied as a liquid that expands to fill gaps and cracks. This creates an airtight seal.

Here are some pros:

• excellent at reducing air leakage

• can add structural support

• highly energy-efficient

• water-resistant

However, there are also cons:

• expensive

• can be messy to install

• may emit strong odors during installation

• not environmentally friendly

4. Mineral Wool Insulation

Mineral wool insulation is made from minerals like basalt and rock, making it a non-toxic option. It's commonly used in attics for its fire resistance and soundproofing abilities.

Here are some pros:

• eco-friendly

• excellent at soundproofing

• fire-resistant

• effective at trapping air

However, there are also cons:

• more expensive than fiberglass

• heavier and harder to install

• can have limited availability

• not ideal for DIY installation

Whatever type of insulation you choose, make sure to hire reputable contractors for proper installation. A well-insulated attic can make a significant difference in home energy efficiency and comfort level.

Exploring the Many Types of Attic Insulation
