All barrier heights are 565mm (22 ¼ inches).


  • Measure between the brickwork as shown in measurement A (overall width of doorframe) For upvc frames exclude the trim at the sides when measuring, as the barrier needs to seal around the flat outside surface of the frame.
  • Choose the flood barrier size which is nearest to Measurement A, but not larger than Measurement A to allow the barrier to clip to and seal against the outside surface of the doorframe.
  • For UPVC frames with no bottom threshold, please choose Floodshield for wooden frames, as this has a bottom seal to seal down onto step. When ordering this PLEASE CHOOSE wooden frame, then later in the order process you must tell us it is a UPVC frame with no bottom threshold in the comments section of ordering.
