What Is the Best Attic Insulation?

Summer will be in full swing here in Tampa soon, which means your AC will be working hard. Don’t let that cold air go to waste by slipping through the cracks of your attic. Make sure you’re prepared by maximizing your home’s energy efficiency to save money and stay comfortable. One way to do this is to install insulation!

As a major source of energy loss, the attic is an important place to insulate. But which type of home insulation should you install? There’s no single answer that fits all situations—it depends on a couple things, such as where you live and the type of attic you have.

What Is the Best Insulation for the Attic?

The biggest factor that will determine which type of insulation you need for the attic is the climate you live in. But in general, there are two types of insulation that are typically installed in attics.


Made of tiny glass fibers and thermally efficient, fiberglass has been used to insulate homes for many years and comes in batt and blown-in (loose-fill) form.

Fiberglass insulation can help:

  • Reduce your utility bills and maximize the energy efficiency of your home or building
  • Make your home or building more comfortable year round
  • Reduce noises from outside and also from inside your home or building between different rooms and levels
  • Improve the performance of your HVAC systems
  • Contribute to a healthier environment

Radiant Barrier

In warm climates like ours, it can be more cost-effective to install a radiant barrier in combination with fiberglass insulation. Radiant barriers are installed in the attic ceiling, right under the roofline, to help your roof reflect (rather than absorb) heat from the sun. This helps your keep your home cooler and more comfortable (and more energy-efficient). Although most homes in our area can benefit from a radiant barrier, this type of insulation is particularly helpful for homes with:

  • Little or no shading from trees
  • Asphalt roofing (which more easily absorbs heat from the sun)
  • Air ducts in the attic
