The wood species used in half log siding significantly impacts its look and performance. Pine is popular for affordability and workability, while cedar offers natural resistance to insects and rot. Douglas fir adds strength and a warm tone, and cypress is prized for durability in humid climates. Each species has unique grain patterns and finishes well with stains. Consider your region’s climate and your siding’s exposure to the elements before choosing. Steel versions can mimic any of these woods while reducing maintenance. Selecting the right species ensures your half log siding project remains beautiful, strong, and long-lasting.
