What Is the Best Attic Insulation?

When it comes to insulating your home, the attic is the jackpot. Why? It’s one of the biggest sources of air leaks in a typical house. There are so many different types of insulation, though, so which one should you use to insulate this space? What is the best attic insulation?

Blown-in Insulation

Loose-fill Fiberglass

For attics, blown-in, or loose-fill, insulation is often used. This includes fiberglass and cellulose. This thermal insulation can be installed in the floors and walls. Blown-in attic insulation offers a number of benefits. It can help:

  • Lower your energy bills
  • Reduce noises between different levels of your home (ideal if you use your attic as a bedroom)
  • Make your home more comfortable
  • Improve the efficiency of your HVAC systems
  • Contribute to a healthier environment

Radiant Barrier Insulation

Radiant barrier, or foil insulation, works a little differently. It’s installed in the attic ceiling, right below your roofing. Radiant barriers work by helping your home reflect, rather than absorb, heat from the sun. However, they are more cost-effective in hotter climates, such as Florida and Southern California.

In addition to fiberglass, spray foam insulation can also be installed in attics.
