If you’re trying to save money on your home energy bills, you may be using your home’s heating and cooling systems less. But did you know that there’s a much better (and more comfortable) way to save money and keep your home at the ideal temperature?

Believe it or not, installing reliable attic insulation is your ticket to lower bills and more efficient temperature control. Curious to learn more?

Keep reading for more information about the benefits of attic insulation and for a full breakdown of the different insulation types available. Let’s get started!

Why Attic Insulation Matters

Attic insulation plays a huge part in keeping your home warm during the winter and cool during the summer. Think of it this way: heat rises because hot air molecules are less dense, right?

So, when the heat releases from your wood stove, furnace, or boiler, it travels upward in your home. If your attic isn’t insulated, you can say goodbye to all that precious heat and the money you spent on it.

Conversely, attic insulation will also help keep your home cool during the hot summer months. Without the right insulation, hot air will seep through the open cracks of your attic and make its way into the rest of your home.

Properly installed insulation is the only way to ensure that your home’s temperature control systems work efficiently and correctly.

Different Attic Insulation Types

To choose the best insulation for your home, you’ll need to understand the three most common types of attic insulation that are available. Let’s break down each option with pros and cons.


As its name suggests, fiberglass consists of plastic that’s reinforced by many tiny glass fibers. It comes in two forms, blankets and rolls.


  • It’s relatively inexpensive
  • If you have even a little experience, you can install it yourself


  • It only works well in standard, unobstructed spaces
  • Fiberglass particles are dangerous for humans and can cause rashes, eye irritation, throat and nose irritation, and stomach irritation
  • Fiberglass traps dust and moisture particles, creating a hotbed for mold growth
  • To handle fiberglass, you’ll need to wear full safety gear (goggles, gloves, long-sleeved shirt, and long pants)

How to Install

If you’re brave enough to install fiberglass yourself, follow these steps. But keep in mind that only experienced handymen and women should handle this type of task.

  • Put on your safety gear
  • Measure the length and width of your first piece needed, adding an inch on each side to make sure it’s a snug fit
  • Put the insulation down on a piece of junk plywood
  • Mark the measurements on your insulation with an easy-to-see marker
  • Use a straightedge to create a cut line along the first measurement
  • Carefully glide a utility knife along the straightedge (you may need a long blade if the insulation is thick)
  • Put the trimmed insulation inside of the intended cavity
  • If the cavity isn’t full, use another piece of insulation on top of the first
  • Repeat this process until the attic is fully insulated, working toward the exit so as not to become trapped

Spray Foam

Spray foam is a type of floor and wall insulation composed of two different chemicals, polyol and isocyanate. When these chemicals come in contact, they can expand to over twice their size.


  • It doesn’t absorb water, preventing mold growth
  • It’s flexible and can settle into any nook or cranny


  • It’s relatively expensive
  • It involves a complex installation process
  • Some types of spray foam insulation have a bad odor

How to Install

Spray foam installation requires professional help. Don’t attempt this installation process by yourself.


Cellulose is a tried-and-true method of home insulation. Most often, it’s made of recycled materials like denim or newspaper. The insulation is most often blown-in.


  • Cellulose is a sustainable and environmentally-friendly material that you can feel good about having in your home
  • The borate treatment in this insulation makes it resistant to pests, mold, and fire
  • It covers hard-to-reach areas with ease
  • It’s the most affordable option for insulation
  • Installation is simple and doesn’t involve harmful chemicals, irritating components, or greenhouse gases


  • Cellulose is a heavy material compared to fiberglass
  • Homeowners will need to make sure their cellulose insulation stays dry
  • It may need upkeep if settling occurs

How to Install

  • Rent a machine to blow the cellulose insulation into your attic
  • Grab a friend who can help you (installation is difficult alone and can get messy)
  • Get proper safety equipment including breathing masks
  • Put on some clothes that you don’t mind getting dirty
  • Load each bag of cellulose into the machine, turn it on, and blow the insulation evenly over the entire surface of the attic
