An animal husbandry tunnel door with adjoining extrusions for closing a tunnel ventilation opening typically in a broiler house has opposing faces with top, bottom and side edges. The faces sandwich an insulation layer. The adjoining extrusions have a first door top, bottom and side extrusion, along with a second door side edge extrusion. The first door top, bottom and side edge extrusions each have parallel inner prongs with barbs and adjacent parallel outer flanges forming two slots therebetween for receiving the top, bottom and side edges of the opposing door faces as the inner prongs with barbs pass into the insulation and are held thereat. The second door side edge extrusion has parallel inner prongs adjacent parallel outer flanges forming two slots therebetween for receiving the other side face edges as the inner prongs with barbs pass into the insulation and are held thereat. The second extrusion has second opposing parallel skirt flanges with inward distal barbs adapted to impinge upon, securely capture and hold the outer flanges of one of the first extrusions of a second adjacent tunnel door.
