When it comes to insulation, there are a lot of different types to choose from; you may be wondering which type is the best for your home (you’re not alone!). Today, you’re going to learn about all the different types as well as the pros and cons of each so that you can make an informed decision.
Fiberglass
The most common type of insulation is fiberglass. It’s made from, you guessed it, glass fibers that are spun into a fluffy material. It’s then used to fill spaces in between walls, ceilings, and floors. Fiberglass is an excellent insulator because it does not conduct heat very well.
Pros:
- Fiberglass is an excellent insulator
- It’s very affordable
- It’s easy to install
Cons:
- It can be itchy to work with
- Some people are allergic to fiberglass
Cellulose
Cellulose insulation is made from recycled paper products that have been treated with fire retardants. It’s then blown into attics and walls using a special machine. Cellulose is an effective insulator because it has a lot of small air pockets that trap heat.
Pros:
- Cellulose is an effective insulator
- It’s made from recycled materials
- It’s treated with fire retardants
Cons:
- It can be difficult to install
- It’s not as durable as some other types of insulation
Spray Foam
Spray foam insulation is made from a mixture of chemicals that are sprayed onto walls and ceilings. When the spray foam expands, it creates a barrier that helps to keep heat in and cold out (perfect for insulation!).
Pros:
- Spray foam insulation is very effective
- It creates an airtight seal
- It’s made from recycled materials
Cons:
- It can be expensive to install
- It’s not as durable as some other types of insulation
Installation Methods
However, it’s not just the materials that differ when it comes to insulation. The way the insulation is installed also makes a big difference in its performance. Here are some of the most common installation methods:
Blown-In Insulation: This type of insulation is usually made from fiberglass or cellulose. It’s installed using a machine that blows the insulation into your attic.
Pros:
- It’s easy to install
- It can be added to existing insulation
- It’s made from recycled materials
Cons:
- It can settle over time, leaving gaps in your insulation
- It’s not as effective as some other types of insulation
Spray Foam Insulation: This type of insulation is sprayed onto your attic floor. It expands and hardens to create a seal that prevents air leakage.
Pros:
- It’s effective at sealing air leaks
- It doesn’t settle over time
- It has a high R-value, meaning it’s a very effective insulator
Cons:
- It’s more expensive than other types of insulation
- It’s difficult to install if you don’t have the right equipment
Blanket Insulation: This is the most common type of attic insulation. It comes in batts or rolls, and you simply lay it down on your attic floor.
Pros:
- It’s relatively inexpensive
- It’s easy to install
- It comes in a variety of R-values, so you can choose the level of insulation you need
Cons:
- It can settle over time, which reduces its effectiveness
- It’s not as effective at sealing air leaks as other types of insulation
Foam Board Insulation: This type of insulation is made from rigid panels of foam, and it’s often used to insulate the walls of your attic.
Pros:
- It’s very effective at sealing air leaks
- It doesn’t settle over time, so it maintains its R-value
- It’s easy to cut and install
Cons:
- It’s more expensive than fiberglass insulation
- It can be difficult to find the right R-value for your needs
