Cordwood

Cordwood refers to a method of building with short, debarked logs laid crosswise like a cord of firewood. These logs are typically 16 to 24 inches long and are laid in a mortar bed. The ends of the logs are exposed on both the interior and exterior walls, creating a distinctive aesthetic.

The history of cordwood construction can be traced back to Native American practices in North America and later to early European settlers. It was a practical building technique, especially in forested areas where wood was abundant and labor was readily available. The method allows for the efficient use of smaller diameter logs and irregular lengths that might otherwise be discarded.

Modern cordwood construction often incorporates principles of insulation and sustainability. Insulation is typically placed in the mortar joint between the logs, or a cavity is left in the center of the wall and filled with insulation. This helps to improve the thermal performance of the building. Various types of mortar can be used, including cement-based mortars, lime mortars, or even cob mixtures.

The appearance of a cordwood home is unique, with the pattern of the log ends and mortar joints creating a visually interesting texture. The exposed wood can be left natural or treated with sealants and stains. The structural integrity of cordwood walls relies on the interlocking nature of the logs and the strength of the mortar. It is considered a durable and low-maintenance building material when constructed properly.
