| Building with
bales of straw was a forgotten art until a few decades ago. Renewed interest
in natural materials has caused a revival for this ancient technique. Straw's insulating properties of
between R-35 and R-45 make it a popular choice when choosing green building
techniques, and it doesn't require a lot of building skill if you're a
do-it-yourselfer. Bales of straw are stacked inside a wooden framework, then
covered with plaster to achieve a look similar to adobe. Strawbales can also
be blended with cob for interesting effects.
