ABSTRACT:
This invention relates to an improvement in a weather seal between a sash and an adjacent side of a window frame and more particularly relates to a weather seal which increases in sealing effect under the impact of wind pressure and consists of a jamb strip having a portion projecting outwardly of the side of a window frame alongside the adjacent side rail of a sash and a flexible weather strip is carried by said projection angled across the juncture of the side of the window frame and sash rail, the strip being positioned to be drawn against the jamb and sash rail, and the strip being pressed further thereagainst for increased sealing effect under the impact of wind pressure. The strip permits free movement of the sash without lessening its sealing effect.
