Abstract
A weatherstrip has a backing strip on which is attached two longitudinal rows of pile. An air infiltration membrane is secured near one end to the backing strip and is supported in upright position between the two rows of pile. When the weatherstrip is disposed in sealing engagement with a closure member, such as a window or door, it provides controlled air infiltration therethrough without increased stiffness which would make movement of the closure member, as in opening or closing the window or door, difficult.
