ABSTRACT Weatherstrip is composed of a substrate having a pile strip upstanding from one surface thereof. In one embodiment the substrate is made of two different materials, one of which is a thermoplastic material that is heat sealed by being passed over a heated bar to prevent the edges of the weatherstrip from fraying. The other material maintains the structural integrity of the substrate during heat-seal- ing. Essentially the whole of the undersurface of the sub- strate including the portion immediately beneath the pile strip contains the aforementioned thermoplastic material, making it possible for the substrate to be surface mounted on a component such as a door or window fabricated of a material compatible to the thermoplastic material. In another embodiment the substrate may be composed entirely or partly of the thermoplastic material, and the same thermo- plastic material is extruded onto the back of the substrate.
