The best way to insulate a basement wall on the interior is with foam insulation that is adhered or attached directly to the concrete. Any of the following insulation materials are acceptable for this purpose: closed-cell spray polyurethane foam, XPS, EPS, or polyisocyanurate.
Extend the outside insulation around the rest of the basement by at least 610 mm (24 in.) beyond the inside wall junction to minimize heat loss at these points. (For information about insulating a cold cellar, see Section 6.2, Insulating the basement from the inside).
