IB-3™ StormStopper Plus is a self-adhering, 50 mil, mineral surface roofing underlayment for use under shingles, tile, and other types of roofing. It is constructed from a strong layer of mesh bonded to rubberized asphalt and coated with black stone granules. Comes with a non-removable selvedge edge for a secure seal on overlaps and an advanced adhesive system for a tight bond to the roofing substrate.
