Basement insulation can be added to interior and exterior walls, in addition to the ceiling. Insulation options include bubble foil, fiberglass, foam board and sprayed foam. The best option for a homeowner will depend on the nature of the basement — finished or unfinished — and budget.

While exterior insulation requires the use of fewer materials than interior insulation, it can end up being a costly option because of the precautions that are needed to install it outside, such as a drainage system. It is, however, effective for reducing the loss of heat that can occur through a foundation and it also protects the foundation from suffering stability issues as a result of temperature changes.

A basement's ceiling is another spot where insulation can be installed to provide a warmer environment or temperature control when an air conditioning system is in use.
