Fire Performance of Finger-Joints
finger-jointed lumberOne type of connection used in the manufacture of wood structural building components is the glued finger-joint. The relative newness of structural building components, and of the finger-joints which are used in them, has raised questions about their performance from the perspective of fire safety. This page provides documents and resources which address these questions.
