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.

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. 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.
Insulating (or replacing existing insulation in) your attic helps:
Our southern California 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. The most cost-effective option would be to combine a radiant barrier with blown insulation.
However, there is no “right” type of attic insulation. We install a variety of insulation in attics:
OJ Insulation even offers environmentally friendly insulation options.
Spray foam insulation can be an excellent way to seal and insulate an attic, as long as it’s 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 and provides impressive air-sealing performance. This can significantly reduce your heating and cooling costs and make your home more comfortable.
On the other hand, spray foam is a bit more costly than other types, 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.

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’re 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.

Yes, you may want to install radiant barrier insulation under your roof, even if you already have insulation in the attic. In southern California and other warm climates, installing both a radiant barrier and thermal insulation in your attic can be cost-effective.
That depends on a few 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 HVAC system you have, the areas of your home you need to insulate, etc.
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.
