Since temperatures have cooled significantly, it’s a good time for Phoenix homeowners to check their attics and walls to see if adding more insulation would reduce heating and cooling bills. The type of insulation you choose depends on where you’re putting it. Regardless, all kinds can lower heating and cooling bills, and since the Phoenix area has a dry climate, most kinds work well to create a barrier between the temperature extremes of winter and summer.
- Batt insulation — The attic contributes to a good deal of heat gain in the summer and loss in the winter. If you’ve ever ventured into your home’s attic during the summer, you know it’s stifling. Adding batt insulation to the attic cuts your heating and cooling load considerably. Most batt insulation is made from fiberglass, and its effectiveness depends on its thickness. Thicker insulation has a higher R-value, which measures how long it resists temperature change for one hour. An R-value of 19 can resist temperature change for 19 hours.
- Radiant barrier — Another type of insulation to consider in Phoenix for attics is a radiant barrier. It looks like heavy-duty aluminum foil and does a good job of reflecting heat away from your ceiling, which lowers air conditioning costs. In order to use radiant barrier, you need at least 1/2 inch of air space between the roof and the rafters or joists to achieve the most benefit. This type of insulation is typically fast and easy to install.
- Blown-in insulation — Good for insulating existing walls, blown-in insulation is another type of insulation that gives good results for keeping homes more comfortable during winter and summer. Installers or homeowners drill holes in the drywall between studs and use blowers to pump in the insulation. Made almost entirely from fire- and insect-treated recycled paper or loose fiberglass, the insulation increases the R-value of exterior walls, depending on how densely it fills the wall cavities. Blown-in also works well for attic spaces.
