To aid in the installation of our header wraps, we have added a thread of our Volcano Fiber 1/4” in from each edge.  This guide-line helps the installer to line up their wrap to get the most efficient use out of it.  The guide-line, using our Volcano  Fiber, is stronger and stands out better than using an offsetting color of fiberglass.
