When building a barn today, most farmers choose to build a barn with plastic (PVC or PE) curtain sidewalls as opposed to a solid wall.  The swine, turkey, dairy/beef are contained to a barn and may require natural ventilation.  Building a barn with curtain sidewalls allows for this.  The natural ventilation not only removes heat and moisture from the building but also odors and gasses.  Utilizing the Agri-Barrier livestock curtain system can allow the farmer to regulate the temperature and moisture in the barn by raising or lowering the curtain as conditions require.
