Can You Use Recycled Materials with Cordwood Construction?

Choosing Recycled Materials

When selecting recycled materials for cordwood construction, it’s essential to focus on items that can withstand the elements and provide the necessary structure for your building. Consider using reclaimed lumber, such as old barn wood, pallets, or fencing, for the cordwood itself. For example, a cordwood wall can be constructed using 3- to 4-inch diameter logs cut into 16- to 24-inch lengths. The logs can be cut from reclaimed wood, such as old tree branches or tree trunks.

Preparing Recycled Materials for Use

Before using recycled materials in your cordwood construction project, it’s crucial to properly prepare them. This involves debarking, cutting, and seasoning the wood to prevent warping or rotting. Debarking can be done using a chainsaw or a debarking tool, while cutting can be achieved using a chainsaw or a miter saw. Seasoning the wood ensures it dries out, reducing the risk of moisture-related issues. For example, seasoning can take anywhere from 6 to 12 months, depending on the wood species and environmental conditions.

Tips for a Successful Cordwood Build

When using recycled materials in your cordwood construction project, it’s essential to maintain a uniform mortar mix and proper insulation. A standard mortar mix consists of 1 part cement, 2 parts sand, and 2 parts water. To ensure proper insulation, consider adding insulation materials, such as recycled denim or cellulose, to the cordwood cavities. This can help maintain a consistent internal temperature and reduce energy costs. For example, a well-insulated cordwood cabin can maintain a temperature of 60°F (15°C) in the winter and 80°F (27°C) in the summer with minimal heating or cooling.
