Cob: Thermal Mass

[Dorothy Bothne]

It's true that the thermal mass from the plaster alone is negligible, but the cumulative affect of everything in the house (walls, floors, ceiling, furniture) would contribute to the thermal mass.  Chandra's strategy is a good routine to follow, Cob or not.

The plaster on lath would not have sufficent thermal mass to do much at
all during a diurnal period, let alone do anything close to a month,
three, or six month lag.

Thermal mass of a thin plaster on lath is nearly negligible.

For structures with a lot of thermal mass this strategy is recommended,
but NOT, just plaster on lath.

Another hint for coping with temps using thermal mass: I let the house
 cool down to 60 or a bit cooler in the spring (April) and allow it to get
 over 90 in the fall (Sept) to give myself a bit of extra wiggle room in the
 extreme seasons.
