Yes. Following an evaluation of issues like point loads, bearing walls, and frost protection, a window or door can be added to an existing Superior Walls foundation. See your SW rep for guidance when considering adding a door or window. As with other procedures that involve revising the existing foundation wall, an engineer or other person competent in applying the structural design principals involved should be consulted. Additional information can be obtained through the "tech resources" link found on the right side of the superiorwalls.com home page.
