Certified tests done on stuccoed straw-bale test panels showed a far greater resistance to fire than a conventional wood frame wall with sheet rock, exceeding recommended building standards. These natural materials do not emit the toxic fumes, released by traditional building materials, in fire situations. The natural elements of cement stucco, plaster and straw breathe to allow any toxins to escape. Straw used as wall insulation reduces the need for the toxin producing manufacturing of fiberglass insulation. In addition, it does not pose the health hazards associated with working with fiberglass insulation.
Straw is renewed annually and is the natural waste of grain harvest.
Substituting bales for lumber products will help alleviate pressures to log old-growth forests. Unskilled homeowners, friends and family can help stack bales and apply stucco saving on labor costs. It lends itself to the community spirit of old-fashioned barn raising parties.
