There are several types of basement wall insulation, including sprayed foam, bubble foil, foam board and fiberglass.

Sprayed foam insulation is a viable choice for a homeowner who is looking for a do-it-yourself option for a finished basement. The foam is applied in exactly the manner as it sounds — with spray cans. It is important to wear a mask when applying this material in order to avoid inhaling the strong chemicals it gives off.

Bubble foil is sold in rolls at hardware stores, making it easy to roll out and attach to a wall with an adhesive. This material is not only a cinch to install, but durable and effective for more many years.

Foam board insulation is often made from a polystyrene or polyurethane material. These insulation panels are useful for adding structural stability to a home, as well as temperature control. While it is possible for a homeowner to install the panels, foam boards often require the help of a professional.

Fiberglass insulation is coated in a vapor barrier that is ideal for locking out the moisture that is common in a basement space. This material — which is known for its ability to last for years — can be easily installed with nails or an adhesive.
