The installation details for insulating sheathing at foundations are generally the same for all foundation types. The intention is to continue the sheathing past the top edge of the foundation or basement wall to create a shingle lap with the foundation. For walls with brick veneer, this may not be possible. In this situation, a seat should be cast into the top of the foundation wall so that the brick and the insulation sheathing terminate at a level below the bottom plate of the stud wall. This will allow a shingle lap joint to be created.
