Blown Insulation vs. Radiant Barrier for Attics

Do you need to insulate your attic? Now that it’s getting even hotter, it is a good time to start. You have a couple different options when it comes to attic insulation: blown-in or radiant barrier. What’s the difference and which one should you install?

Blown-in Insulation

Blown-in (loose-fill) insulation can be either cellulose or fiberglass.


This insulation can be installed in attic floors and walls and is an effective solution for stopping heat transfer. Blown insulation or a blown-in blanket system can be installed. Blown-in solutions offer a number of benefits. They 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 overall efficiency of your AC
  • Help protect against water infiltration and moisture issues

Radiant Barrier Insulation

Radiant barriers are typically installed in attics, right under the roof, to help your home reflect sunlight. This reflective insulation can keep your home a lot cooler and more comfortable—and help you save on your energy bills.

Radiant barriers are ideal for any attic and for any homeowner who wants to maximize their home’s energy efficiency—but they are particularly beneficial for homes with:

  • Little or no shading from trees
  • Asphalt shingle roofing (which easily absorbs heat from the sun)
  • An unusually hot and stuffy second story
  • Air ducts in the attic
