On average, American households spend $1,900 on their utility bills. Of this number, heating and cooling take the lion’s share, accounting for 54 percent of the monthly expenditure on bills often due to poor attic insulation.

There are plenty of ways to reduce expenditure on heating and cooling, including turning off lights and appliances when not in use and switching to energy efficient electrical devices.

Another effective way to reduce your energy bills is through insulation, which includes attic insulation.

Your home loses heat due to several reasons. These include poor insulation, using the wrong size of heaters, the presence of holes in the exterior walls, and leaks in the ducts. According to studies, heat loss in the roof and attic account for the total heat loss in a home. Heat loss in walls, windows, doors and floors account for the rest.

Through proper insulation, you can reduce your energy bills by as much as 20 percent while reducing heating and cooling costs by as much as 40 percent. With these savings, your attic insulation will practically pay for itself.

There are several other benefits of attic insulation, apart from cost savings. For one, you will be able to keep your home cooler during the summer by reducing the effects of radiant heat. This also means that your air conditioning unit will not work harder just to attain a suitable temperature.

In the winter, your home can become warmer as cold drafts are prevented from coming into your living space. Plus, your furnace will not be burdened by the entry of additional cold air.

Finally, insulating the attic will help keep molds and bacteria at bay. When heat and moisture are eliminated, the chances of these microorganisms living in your attic will be minimized. Furthermore, the health risks posed by these microorganisms will be substantially reduced.

If you are planning to have your attic insulated, it is best to leave this task up to the professionals. They will know exactly what to insulate. For example, if the attic is only used for storage, these professionals will recommend insulating the whole floor. On the other hand, if the attic is heavily used, these experts will recommend insulating above the finished spaces. They can also identify whether your current insulation is still effective or not.

Finally, experts in the installation of insulation can help you determine which type of insulation is suitable for your home. Among the most commonly used insulation materials are fiber glass batts and cellulose insulation.
