A sealing strip for preventing or reducing gas flow in an unwanted direction through an elongate gap, such as the gap between a door or window and its associated frame, and comprising a lip portion extending along the length of the strip and an attachment portion extending along the length of the strip for securing the strip in position adjacent to one side of such a gap, is characterized by said lip portion being flexible and capable of being deformed into sealing engagement with the opposite side of the gap, at least partly to seal the gap, by gas flow into the gap in the unwanted direction. A method of preventing or reducing gas flow in an unwanted direction through such a gap by using such a strip is also disclosed. |
