Abstract: A weather stripping apparatus for use around doors or windows. The apparatus comprises a flexible elongate tubular member which is generally flat and has a plurality of openings along the front edge. Self-adhesive tape is provided for attachment of the apparatus to the area to be insulated. The openings are exposed to the air whose flow is to be inhibited. Any movement of the air caused by wind or the like will cause the air to enter the openings and inflate the weather stripping apparatus, sealing gaps between the door or window and its frame through which air would normally flow.
