Attic Insulation in San Diego & Los Angeles, CA

The attic is the first place you should look when it comes to maximizing energy efficiency and saving money with insulation. 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 residential insulation in California, OJ Insulation can handle all your needs. We can install any insulation in your attic, including:

Our Southern CA home insulation experts typically recommend radiant barrier insulation for attics. 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.

Never ask, “Where can I find the best attic insulation near me?” again! If you need home insulation in the L.A. or San Diego area, OJ Insulation is the only name you need to know.

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 insulation. Many types of insulation are good at stopping heat transfer.

  • Fiberglass insulation effectively stops heat transfer into a colder area (heat leaking out of your warm house into the cold winter air!).
  • 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.
  • Spray foam insulation is extremely energy-efficient because of its high R-value and is great for insulating hard-to-reach places because of the liquid spray application.

OJ Insulation even offers environmentally friendly insulation options for your project!

Insulating (or replacing existing insulation in) your attic helps:

  • Reduce your utility bills and maximize the energy efficiency of your home
  • Make your home a more comfortable space with more consistent temperature throughout
  • Improve the efficiency of your heater and air conditioner since they likely won’t have to work so hard to regulate your home’s temperature
  • Reduce noises on different levels inside, which is especially useful if your attic is used as a living space
  • Contribute to a healthier air quality environment inside your home

The Pros and Cons of Using Spray Foam in an Attic

Spray foam insulation can be an excellent way to seal and insulate an attic, as long as it is done correctly. With R-values of 6.0 per inch for closed-cell forms and about 3.6 per inch for open-cell versions, spray foam offers excellent insulating performance. Because it expands to fill any gaps or voids in the framing, it also provides impressive air sealing performance. This can significantly reduce your heating and cooling costs and can make your home more comfortable.

On the other hand, spray foam is a bit more costly than other types of insulation, and there can be problems if installed improperly, such as mold and moisture issues. If closed-cell spray foam is installed on the underside of the roof deck, it may shorten the life of your roof, though open-cell foam can breathe enough to be used successfully. A professional installer, like our experts at OJ Insulation, can avoid these pitfalls by providing a proper, energy-efficient installation.

Where to Use Spray Foam in an Attic

Open-cell spray foam can be used on the underside of the roof deck, in knee walls, in eaves and in the attic floor. Closed-cell spray foam should only be used in the attic floor and knee walls. Using it on the roof deck will prevent the attic from venting properly and could harm the roof unless airspace is added between the roof and the insulation.

If you are insulating the attic floor with spray foam, any existing insulation should be removed to avoid condensation and air quality issues. Airspace should also be maintained around hot surfaces like appliance flues, chimneys or non-contact-rated recessed lighting.

Frequently Asked Questions

Should I install radiant barrier insulation even if I already have attic insulation?

Yes, you may want to install radiant barrier insulation under your roof, even if you already have insulation in the attic. Here in Southern California and other warm climates, installing both a radiant barrier and thermal insulation in your attic can be cost-effective.

How much insulation do I need to install?

Well, that depends on a few different factors, the biggest two being the age of your home and the climate zone you live in. The amount of insulation you need to install will also depend on the type of heating and cooling system you have, the areas of your home you need to insulate, etc.

What does R-value mean?

You may have heard the term R-value before concerning insulation. The R-value of a type of insulation measures how well it stops heat transfer; the higher the R-value, the better! However, it depends on the insulation’s material, thickness and density.
