摘要： A fiber mat includes an assembly of fibers including a minority portion including a set of polymer fibers and a majority portion including a set of fibers different than the minority portion, wherein the minority portion is a plane parallel to a plane of the majority portion of the assembly of fibers; and a binder including an organic resin, wherein an air permeability of said fiber mat is not substantially different from an equivalent weight fiber mat containing a homogenous mat structure and wherein the fiber mat provides at least a 5% increase in tear when placed in a bituminous roofing product compared to an equivalent bituminous roofing product made with the equivalent weight fiber mat containing the homogenous mat structure.
