Is rammed earth suitable for the cold Canadian climate?
Absolutely, in fact our insulated rammed earth walls have 50% more R-value (R33) than a typical Canadian home (R22). We use four inches of special rigid insulation in the centre of the wall keeping the heat in and the cold out. One of the most important aspects of a rammed earth wall is the thermal mass; a rammed earth wall 2 feet thick can store heat energy between 24 to 48 hours, which can help stabilize the indoor air temperature during winter.
