How to fit Weather Bars on an Exterior Door - DIY Tip 16
Advice on fitting a weather bar varies depending on the type of bar or drip chosen, so make sure you carefully read any manufacturer's instructions and/or directions.
Start by measuring the width of the door and cut any top drip (timber or otherwise) to the width between the door frame stops, this is the area on the external face that is narrowest in width between the frame, not the jamb, if using a bry dry (as described below) the part that sits on the floor or sill should be cut between the door jamb. Cut a slight angle to any of the weather bar top drips as this is required at the end where the door meets the frame on the lock side, this will prevent the bar jamming when the door is swung open or closed.
It is better (in our opinion) to use the Bry dry (or Weatherten bar - shown above) rather than the timber weather drips (shown below) which are very traditional and are normally fitted to the face of the door at the bottom rail. The bottom of the bry dry type bar is fitted between the door and the door step or sill and incorporates a drip which when fitted to the door interlocks as the door is closed.
When fitting a timber weather bar to the door, use screws and a waterproof adhesive, remember to fill the screw holes after fixing, to prevent water seeping in. Make sure you have also sealed the join between the weather bar top drip and the door to prevent dampness."
