Any butt joints or seams create a ballistic weakness. To insure ballistic integrity, we recommend that you incorporate 4" overlap strips (battens). These strips insure a 2" ballistic overlap on the back of each side of the seam. Conformity to curved surfaces can be handled by placing 12" to 18" vertical strips following the inside curvature of the surface to be protected. The same 4" overlap strips should be employed at each joint.
