Weatherbar E seal draught excluder is a very close cell rubber compound with an adhesive backing.  The elastic properties of the rubber seal ensure it has an excellent shape “memory” meaning it can withstand many thousands of door or window openings and closings without fatiguing.  The self adhesive backing provides a strong bond with the frame ensuring the profile stays in position.  A fibrous backing to the adhesive tape helps the profile to maintain it’s shape under stress. EPDM rubber seal is a great solution to draughts caused by ill fitting or warped doors and windows.  The three fins on the E shaped profile provide a triple seal when in contact with the door or window.
