  Insulating the walls of a basement will help warm the entire house and lower electric bills. According to Energy Savers.gov, up to $390 a year can be saved on the electric bill by simply insulating the basement. Basement wall insulation can be installed during construction of a home or added to an existing basement.
  
  

Fiberglass

• Fiberglass is an effective insulation material that can be quickly installed in the basement. Fiberglass insulation can be purchased in rolls, safely coated in a foil vapor barrier for easy handling and to protect the insulation from moisture. Fiberglass can be applied to basement walls using nails, glue or other adhesives. Once installed the wall can be finished with drywall or left unfinished, providing the same level of insulation for up to 50 years.
  
  

Spray Foam

• Spray foam creates a porous insulation barrier and can easily be installed by the amateur. It is available in spray cans from building supply stores. A wooden frame must be installed before applying the spray foam, as it must be sectional. Wooden posts every 3 feet are sufficient. A protective breath mask must be worn during application as the product has a heavy chemical smell. The foam can be left unfinished, providing insulation for up to 20 years.
  
  

Foil

• Rolls of bubble foil insulation can be purchased from specialty stores. Often accompanied by an adhesive back, the bubble foil is very easy to install. The foil can be rolled out using the adhesive to attach it to any wall surface. Once installed, drywall or concrete can be added to finish; if left unfinished, it will provide effective insulation for up to 25 years.
