If you’re looking for ways to save energy in your Phoenix-area home, take a look at your home insulation. In addition to keeping more energy dollars in your pocketbook, upgrading your home’s insulation enhances comfort in all seasons and reduces the load on your A/C and furnace or heat pump. Use this guide to discover where your home may use an insulation booster.

Unfinished Attics

Insulate between and over floor joists in unfinished attics. If the air ducts are located in your attic, you may consider insulating the rafters to bring your attic space into the conditioned spaces of your home. Alternatively, insulate air ducts with rigid-foam insulation or fiberglass rolls. Fiberglass rolls or loose fill are also good choices of insulation for floor joists.

Additional insulation materials used for floor joists are loose-fill cellulose and foam-in-place insulation.

Finished Attics

If you’re retrofitting an unfinished attic for an additional bedroom or other purpose, insulate between the studs of knee walls and the rafters of the roof and exterior walls. Fiberglass batts are a practical insulation for these applications.

Exterior Walls

If you’ve discovered that your exterior walls are lacking insulation, using foam-in-place insulation is the most practical solution. Foam-in-place insulation is pumped inside exterior walls through small holes. You don’t need to rip down drywall to insulate.

Insulate solid foundation walls located above ground level with rigid foam insulation. Wall cavities may be insulated with foam-in-place insulation. Rigid foam insulation also works well for the walls of heated basements.

Unconditioned Spaces

The floors above unconditioned spaces, such as crawl spaces and garages, may be insulated with foam-in-place insulation or rigid foam insulation that is resistant to moisture. Avoid using fiberglass rolls or batts to fend off mold problems in these areas.

Cover dirt floors of crawl spaces with polypropylene sheeting to help prevent mold and pests. Polypropylene also seals your home against radon exposure. Radon is an odorless and invisible cancer-causing radioactive gas that is naturally emitted from the ground.
