# Bamboo Plywood

Bamboo plywood is a wood-based material. It has a moderately high ductility and a moderately high thermal conductivity among wood-based materials. The graph bars on the material properties cards below compare bamboo plywood to other wood-based materials (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
