Insulation of an interior foundation wall

Nuitari | Posted in Green Building Techniques on

The home I’m living in had an extension built with a full foundation, which also provides a heated room in the basement. I’ve noticed that no insulation was boot on the old foundation wall.
Should it be insulated or is it not needed?

Both rooms around that cement (foundation) wall are heated, but only one has AC (too complicated to pass a forced air duct to the new room).

    Stephane,
    What is your location or climate zone? If you live in the U.S., the 2012 International Residential Code requires basement insulation for all homes in Climate Zone 3, or anywhere colder.
