What are Angle Fillets and Firrings?

An Angle Fillet is a piece of wood that has a triangular cross-section that is designed to fit into the corner where two pieces meet. A Firring is a piece of wood that has been cut along the fill length diagonally.

They serve two purposes: The first is to prevent the sharp corner from damaging the felt or membrane. The second purpose is to allow water to run-off easily.
