Over on Straw Bale Construction at Cardinal Bluff, there is a post entitled “Straw Bales Comin’ Atcha…Some Flat Side Up, Some Edges Up“. The discussion revolves around the direction to lay the straw bales in the walls. Should they be placed ‘flat’ side up with the stems showing or ‘edge’ side up with the cut ends showing?
Flat is easier to place, especially with post and beam process because the strings go with the line up without necessitating a clumsy cut. The edge side requires the strings to be cut when working around the posts and the beams. That means the straw bale must be re-tied to hold it together tightly.
However, the edge side does present a slightly more narrow wall, leaving a few more inches of floor space. That little bit can be important on a small footprint.
Research, measuring, thinking and more thinking are required to make the decision about flat or edge. Under a load bearing building process, the walls will be 14 inches thick with the edge presentation as compared to the 18 inch thickness with flat straw bales. For a shorter wall, that isn’t an issue, but if a two storey or storey and a half is chosen, then, more thought needs to be put into the choice. Will 14 inches satisfy you? Will you have a back-up measure to further strengthen the wall?
Edgy or Flat, that is the Question, but there are many sub-questions.
Thanks for stopping by to read my thoughts on the matter. Richard.
