To accommodate substantial variations in the dimensions of door openings, a skinned or panel door (fig. 5) has a frame 4 defining recesses 5 for receiving a pair of door panels 1,2 of variable size. The recesses also define a projection wall 7 surrounding the free edges 8 of each panel 1,2 to protect the exposed free edge of particularly GRP panels from the ingress of water and the action of sunlight. In a further embodiment (fig. 3), a flange 9 may overlie the margin of the exterior face of each panel.
