When you look at your home’s energy bill, 50% – 70% of your total comes from heating and cooling your home. That’s because the greater the difference between the indoor and the outdoor temperature, the more energy it takes to maintain a comfortable temperature inside. You can take active steps to reduce your energy bill by making your home more energy efficient. Add weather stripping, caulk, or foam to your home’s doors, windows, roof, and anywhere outside air may be able to enter your home. Next, make sure your home is properly insulated.

Types of Insulation

Insulation is made from a variety of materials, and generally comes in four types:

  • Rolls and Batts: are flexible products made from mineral fibers. Rolls are available in pre-cut widths and continuous lengths (ranging from 20 to 40 linear feet) to fit between studs and joists. This type of insulation is ideal for areas where longer runs are needed such as attics and floors. Batts are designed for easy handling and are available with or without paper or aluminum foil facing. They can be used in floors, walls, attics, and ceilings.
  • Blown-in/Loose-fill: loose fibers are blown or sprayed into spaces using special pneumatic equipment. The material then conforms to odd-sized cavities and hard to reach areas such as attics with wires, ducts, and pipes.
  • Foam Board: Rigid panels of insulation that are very effective in interior sheathing for basement walls, exterior wall sheathing, and attic hatches.
  • Spray Foam: Latex or polyurethane spray foam insulation is sprayed into place with a can or specially designed equipment. It can be blown into walls, on attic surfaces, or under floors to fill small gaps, holes, and cracks.


The type of insulation you should choose depends on your home design, your budget, and what R-value you want to achieve. Your R-value is dependent on your climate, your home’s heating and cooling system, and the part of the house you plan to insulate. For most of the state of GA (excluding the northern border), the U.S. Department of Energy recommends adding R30 to R60 insulation to an uninsulated attic, R25 to R38 to an existing 3–4 inches of insulation, and R19 to R25 for floors.

Your HVAC system

Your HVAC system needs twice yearly maintenance in order to run properly and efficiently. If your home still feels cold and drafty after sealing and insulating, your heating or air conditioning system may not be functioning properly. Call the professionals at Atlanta Air Care to evaluate your HVAC system and perform any necessary maintenance so you and your family will stay warm and toasty all winter long.
