A Guide to Home Insulation Basics in Mobile AL

Published on: June 8, 2012

The U.S. Department of Energy estimates that 44% of the energy used in homes is used to heat or cool the home. Because the energy that is used to heat and cool homes is non-renewable energy, home insulation is becoming more of a priority now than ever before.

Home insulation keeps conditioned air inside the home. For homes in Mobile AL, where the summers are long and hot, keeping cooled air inside the home is a necessity for homeowners, so adequate insulation is of utmost importance. In homes with insufficient attic insulation, a substantial amount of conditioned air is lost through the attic. Attic insulation is an excellent way to lower heating and cooling costs for your home.

Attic Insulation Lowers Energy Costs
A well-insulated home, particularly one with attic insulation, will lower energy bills and keep the home cooler in the summer months and warmer in the winter. For homes in Mobile AL, attic insulation, as well as properly insulated walls and floors, will save the homeowner money in lower utility bills. Attic insulation will likely provide the most return on investment in terms of lowering high energy costs.

In addition to lowered energy costs, insulation acts as a sound barrier. Well insulated walls and ceilings will tend to block outside noise and provide a sound absorber between rooms. Attic insulation may be installed by an AC maintenance or service company.

Types of Insulation
Various types of material are used to insulate homes, including:

– Fiberglass
– Foam
– Cellulose
– Mineral Wool
– Cotton

An AC maintenance professional will advise you with regards to the optimal type of insulation for your application.

What Does R-Value of Insulation Mean?
The R-Value of insulation is the value that measures resistance to heat flow. The higher the R-Value for the insulation material, the greater resistance the material will be to the flow of heat through walls and ceilings. The R-Value of the insulation material is posted on the packaging of the material. Your AC maintenance professional will be able to tell you the minimum requirement for the R-Value of insulation for your home. For homes in Mobile AL, the R-Value will be different than homes in the northern United States. This is because the R-Value varies between different climate zones. The R-Value is cumulative. This means that if two layers of insulation with an R-Value of 18 are installed, one on top of the other, the insulation will have a cumulative R-Value of 36.

For more information about the R-Value for the insulation that is recommended or required for your home, consult with an AC maintenance company. R-Value recommendations vary depending on the area of the country. A qualified AC maintenance service that is familiar with insulating homes in your area will know the most effective R-Value for your application. Proper insulation will ensure that the conditioned air stays inside your home and will make your home more sound proof. Save money and improve the comfort level of your home by making sure insulation is installed and maintained.
