Attic Insulation in San Diego & Los Angeles


When it comes to maximizing energy efficiency and saving money with insulation, the attic is the first place you should look. Insulating your attic (including knee walls) is one of the easiest ways to make your home more energy efficient. As you probably know, hot air rises, making attics one of the biggest sources of heat loss in your home—but you don’t have anything to worry about if your attic is properly insulated!

If you’re looking for attic insulators in California, OJ Insulation can handle all your needs. We can install any type of insulation in your attic, including:

  • Radiant barrier insulation (or foil insulation)
  • Fiberglass insulation
  • Cellulose insulation

Our CA home insulation experts typically recommend radiant barrier. Radiant barrier insulation (or foil insulation) is a good option for attics because it increases your home’s ability to reflect, rather than absorb, the sun’s energy.

Benefits of Insulating Your Attic

Although you may not go up in your attic every day, it doesn’t mean you should overlook the space when it comes to insulating your home! In fact, if you fail to install attic or loft insulation, your home—particularly the second story—will be much hotter and more uncomfortable in the summer.

Although foil insulation is recommended, there is no “right” type of attic insulation. The most cost-effective option would be to combine a radiant barrier with blown-in insulation. Many types of insulation are good at stopping heat transfer. Fiberglass insulation is very effective at stopping heat transfer into a colder area (heat leaking out of your warm house into the cold winter air!). And last but not least, cellulose insulation has similar qualities to fiberglass and is great for re-insulating all areas in your home, including the attic. Radiant barrier insulation, as mentioned, helps your home reflect heat from the sun, keeping your home significantly cooler. OJ Insulation even offers environmentally friendly insulation options for your project.

Insulating (or re-insulating) your attic ensures:

  • Lower energy bills
  • More comfortable space
  • Uniform temperature throughout your house
  • Reduced outside noises

Our team installs retrofit insulation and also insulates new attics.
