PHOENIX -- With the summer heat just around the corner, now is the time to insulate the attic to help save energy and money.

The proper type of insulation combined with the proper amount can help lower your electric bill by up to 20 percent.

Here in Arizona, attics need an R30 to R60 Insulation in the attic to be the most efficient.

Liquid foil is also an option. It blocks 80 percent of radiant heat entering your home, lowering your attic temperature by as much as 20 degrees and your energy bill by up to 15 percent.

Liquid foil comes in a 5-gallon bucket for approximately $250. It is silver in color and sprayed through a paint sprayer.

Each home is different, so here's how to determine the right insulation for yours:

1. Measure the attic (width times length).

2. Measure the height of the existing insulation to determine how much more you will need to protect your hom's  efficiently.

3. Determine if you prefer rolled or blown-in insulation.

4. For blown-in, it can be a do-it-yourself project. You can rent the machine from Home Depot's tool rental department. The rental is free with the purchase of 10 insulation bags. To have the service done for you, call 1-800-Home Depot for a free estimate. The cost is about $1 per foot.

5. For rolled insulation, determine the proper insulation and, wearing gloves and protective eyewear, roll out the insulation in between the joists and rafters in your attic. You can also staple it down if desired. There are insulation supports available for unsturdy ceilings.
