Where welded wire mesh is used as the structural shear of a building, it is very important that temporary braces be used to secure the building before the mesh is applied. This is a common practice with conventional construction as well. 2×4 braces are used to support the walls and maintain a plumb line until the plywood is added. In a bale house, the system is a bit harder to deal with.
Consider the placement of the temporary braces. If the braces are placed on the inside of the frame, they will need to be removed when stacking the bales and the structure ends up free of lateral support. If the braces are placed on the exterior of the building, they need to be removed before the exterior mesh is installed. The exterior mesh holds the greatest amount of strength for the structure as it is fastened directly to the vertical framing as well as the top and bottom plates. The interior mesh is only attached to the plates and then sewn to the exterior mesh. Therefore, the mesh with the greatest strength has to be installed for the interior mesh to work at full capacity.
So how to deal with this dilemma? I install my braces on the outside of the frame during construction. The first pieces of mesh are placed on the interior faces of the wall after baling. They are placed as close to directly opposite of the temporary braces as possible. Once all of the interior slices of mesh have been fully installed, move to the exterior. I remove one brace at a time from the exterior and immediately install the mesh. I continue to install the mesh as I move down the wall until I get to the next brace. Only after all the mesh on the outside of the wall has been installed from the last brace do I remove the next brace. I continue down the wall in this fashion, never removing more braces than I can mesh up to. This gives me continued lateral support throughout the meshing process and limits the risk of the walls falling out of plumb.
