What Are The Different Kinds of Attic Insulation?

If you’re considering attic insulation installation or replacement, it can be an overwhelming process. You want to make sure you have the right amount of insulation to keep your home efficient, but first you need to decide on the right kind of insulation material.


Go Green Heating and Cooling wants you to be as informed and educated on your attic insulation options before you make a decision. This material will be protecting your home for many years after all! Read on to learn more about the main kinds of insulation used in attics and their pros and cons.

Types of Attic Insulation

Our team knows that every home is different, and that’s why we can’t recommend one kind of insulation material as the best for all situations. Your home deserves a specific evaluation to determine which material is best for your circumstances and will help regulate your heat the best. The following are the most widely used insulation materials to consider: 


Fiberglass may not be the fanciest insulation material, but it is the most popular of your options, by far. This inexpensive and widely available material is used in many homes across the nation. The material is fantastic for resisting moisture in high humidity areas and can resist fire as well. Also, it doesn’t shrink over time and insects don’t eat it, allowing your investment to remain intact for years. 


Cellulose is even cheaper than fiberglass insulation, making it the most inexpensive option for insulation installation. However, this material is made with high levels of wood and paper, making it a fire hazard. The material can be treated with anti flammable chemicals to lower the risk, but you should be aware of it. Cellulose also absorbs more moisture than other materials, making the risk of sagging and mold growth increase as time goes on.

Mineral Wool

Mineral wool is made up of melted stone and recycled steel. It is a pricier option than fiberglass, but there are more advantages to using this material as well. Mineral wool is extremely fire and water resistant, protecting your home from unexpected fire and severe leaks. It also has the unique ability to muffle outside noise and prevent it from entering your home.


One of the safest options available to you is cotton insulation, often made out of recycled blue jeans. The cotton in this material traps heat just as well as your other options. Plus, it poses no threat to your health when you are handling, installing or around it. It’s also an inexpensive option that could work for your budget.


Foam insulation is primarily used in commercial projects, but it tops the rankings as far as performance goes. The expanding foam material creates a seal preventing any air from escaping or invading your home. It’s impermeable to water, which means no leaks or mold will ever affect its ability to protect your home. It also never wears down, no matter how hot your attic gets in the summer.

Need Attic Insulation Installation?

The key thing to remember when considering adding insulation to your attic is that most materials need professional experience to be installed. Don’t risk future problems or air leaks that could have been prevented. Contact the team at Go Green Heating and Cooling to feel confident that the job is done the right way!

Betsy W.

Professional and Honest

After receiving a ridiculously high quote from the HVAC company sent out by our home warranty, my husband wanted a second opinion. Our technician Mike was thorough and honest about what needed repair. Not only was the diagnosis much simpler, so was the price. Mike got the repair done quickly and was very professional. We’ll definitely be calling Go Green again.
