摘要

The wall has a recreation room to keep animals i.e. pigs, where the wall is made of plastic. A buffer area separates a lounge to conduct air, and air ducts allow flow of air from a buffer space in the lounge, where the lounge is located above or below a main lounge area. A stretching air duct is provided between wall surfaces for providing a communicating connection of the buffer space in the lounge. Vents extend between two opposite plate-like walls, respectively, and have an inlet in a plate-shaped wall. A connecting wall is provided between two bodies. An independent claim is also included for a method for manufacturing a boundary wall.
