Abstract
An arrangement in doors including a door leaf of a first material provided with an insert of a second material having properties differing from those of the first material. The first and second materials are sufficiently flexible to allow opening and closing of the door leaf by winding the door leaf respectively on and off a roller. The insert is replaceable and is attached to the door leaf by at least one row of loops secured to the door leaf and the insert. The loops are interdigitated and interlocked by a pintle wire inserted through the interdigitated loops to establish a pin seam so that the insert may be detached and re-attached to the door leaf. Further disclosed is a covering fabric which covers the insert and is attached to the door leaf by hoop-and-loop fasteners.
