ABSTRACT:
A pile weatherstripping has a continuous length of a resin anchorage base with even lengths of filaments secured to opposite sides of the base along the length of the base and extending away from the base in the same general direction on each side of the base. The filaments are long enough and dense enough to form insulating pile rows extending out of a retainer slot in which the anchorage base has an interference fit. A sheet resin fin preferably extends continuously outward from the base between the filaments on the opposite sides of the base, and such a weatherstripping is preferably made by wrapping a multifilament yarn around a plurality of bases, securing the yarn to opposite sides of the bases, and then slitting to separate each individual weatherstrip.
