How are utilities installed on a foundation wall with interior rigid foam?
How are electrical and other utilities installed on a basement foundation wall (8″ poured concrete) that has 2″-3″ of rigid foam insulation installed on the interior side? We have some sections of the basement walls we plan to finish right away and others where we only want to insulate and add electrical for now. Are the utilities installed over the foam or does the foam typically get notched out? We are planning to build the stud walls against the foam and insulate the cavities with dense pack cellulose for both the walls we finish right away and the walls we finish later.
Thanks in advance for your feedback.
