Answer | Clay for building has simillar insulation property to
rammed earth as it is the same material just applied in a
different way. As you have mentioned it really performs
best where thermal mass is needed. Straw bales have
insulation value twice that of the building regulations
reguirement. When you mix the two together, depending on
what proportions you mix you get somewhere in between the
two. The best straw clay walls for this type of climate are
ones where you mix as much straw with the clay as possible,
to obtain as high an insulation value as possible, then
apply thick internal earthen plaster and south-facing
windows for the earthen plaster to act as thermal mass
inside.  |
