Protecting bottom edge of exterior foam insulation board
Which would be better to protect the bottom edge of 1-1/2″ exterior foam insulation board: using a piece of 1-1/2″ x 1-1/2″ treated wood around the perimeter of the house between the foundation and sheathing or using a piece of aluminum flashing bent in an L shape like a big drip cap? The foam insulation board would sit on top of either the treated wood or the L shaped flashing protecting it from insects and mice as wells as keeping it dry. Thanks.
