Rigid Board/Foam Board Insulation
Foam Board insulation products are an efficient way to dramatically increase the overall thermal efficiency of your home. These boards are lightweight, noncorrosive, easy to cut and an excellent continuous insulation option.
Because of its resistance to moisture, foam board insulation is a great choice whenever and wherever there is a chance it could get wet, such as: an exterior foundation, inside a basement against the foundation, and on the outside of a house beneath a house wrap. Foam board insulation is more expensive than traditional batt insulation, so use it only when moisture is a factor and it makes sense with your budget.
