Outside Corners
Corner with Sheet Metal Backer
Overlap the panels past the corner by the thickness of the panel (i.e. 2½” for EXe 2.5) creating an overlapping butt joint. Leave a ¼” gap at the butt joint for foam sealant. Corner posts can be attached with a 4” screws directly back to the framing when an InSoFast stud is not located near enough to the corner for siding attachment. Sheet metal flashing may be added behind the corner post for siding fastening at the corner post.
