Astragal is a term used for the seal that seals the central join between two swinging doors, the join being known as the 'meeting stiles'.

A number of extra problems have to be faced when sealing a meeting stile. These include whether or not the seal will interfere with the centre latch, door closers, flush bolts and bottom threshold seals.
