Composite Fir Lumber

A composite lumber made from a combination of wood and plastic.

Notes

Composite Fir Lumber is a tier 5 building block crafted from a mix of wood and plastic at a Composite Lumber station. It is a softwood lumber product used in high-end construction and advanced recipes, including the Computer Lab, Modern Upgrade 3, and various composite furniture items. Because it is a high-tier material, stocking it in town stores helps residents build better rooms for improved housing value and faster skill progression.
