As a significant source of energy loss in homes, the attic is a good place to insulate. Whether you’re a builder working on new home construction or you need to re-insulate the attic of your 20-year-old house, we recommend starting with the attic!
But what kind of insulation should you use? While your best bet is talking to insulation professionals, it’s helpful to have a little background information about insulation for attics, as there are a few different options.
Types of Attic Insulation: Thermal & Foil
In general, there are two main types of attic insulation: thermal (fiberglass and cellulose) and foil (radiant barrier). It’s not an either/or situation—in warm climates, like here in Southern California, an attic should have both types.
Blown & Batt Insulation
Blown-in cellulose and fiberglass can also be cost-effective attic insulation solutions, even with a radiant barrier.
Cellulose insulation can be installed in various parts of the attic. Not only is cellulose one of the most environmentally friendly types of insulation, but it also offers superior soundproofing abilities.
Blown-in fiberglass insulation can also be used for attics, and it offers the same benefits as cellulose. Fiberglass helps keep your home more energy-efficient and comfortable all year round. Batts can also be used.
Thermal attic insulation can help:
- Lower your energy bills
- Make your home a lot cooler and more comfortable
- Improve the performance of your HVAC systems
- Contribute to a healthier environment (decreased energy consumption leads to fewer greenhouse gas emissions)
Radiant Barrier Insulation
Installed under the roof, radiant barriers work differently than other types of insulation. One of the best types of insulation for attics—especially in warm climates—radiant barrier is foil insulation that is installed to keep your home cooler and more comfortable. It does this by helping the roof reflect, rather than absorb, heat from the sun.
Radiant barrier attic insulation helps:
- Lower your energy bills
- Make your home a lot cooler and more comfortable
- Improve the performance of your AC
- Contribute to a healthier environment (decreased energy consumption leads to fewer greenhouse gas emissions)
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
