Abstract: Standard weather stripping composed of a backing strip and a pile body projecting from one face of the backing strip is guided into a channel having a pair of spaced apart side walls and a bottom wall. Also guided into that channel and positioned against the side of the pile body is an impervious resilient film barrier which extends from the top of the pile body down to the base thereof and across the adjacent side edge margin of the backing strip. The channel side walls are clinched against the bottom wall thereby capturing the weather stripping between those walls and bending the film barrier adjacent the base of the pile body so that the resiliency of the barrier tends to bias the portion of the barrier projecting out of the channel against the pile body so that it remains in an erect position and prevents moisture and drafts from penetrating into the pile body.

Abstract: Weather-stripping especially for slidable closures such as windows, wherein the weather-stripping comprises a flexible plastic foam substrate provided on at least a part of its outer surface with a tough abrasion resistant skin. The weather-stripping is compressed into a confining channel in one closure member, and is provided with flocked fibers extending away therefrom to engage a second closure member to prevent the infiltration of air and water. The substrate may preferably comprise ionomer plastic foam. The outer skin may be of the same material as is the cellular substrate or it may be a different material, e.g. laminated to at least one side of the cellular substrate to provide a smooth yet abrasion resistant surface. Specific cross-sectional shapes of weather-stripping are disclosed, together with manufacturing methods wherein the weather-stripping is shaped while in sheet form and then is slit into strips for insertion into the channel member.
