• a body that is elongated, wherein the body, when viewed in cross-section, comprises a perimeter wall with an interior cavity, wherein the perimeter wall comprises:
• a first wall portion that extends in a first direction, wherein a width of the first wall portion is based on a thickness of exterior insulation installed or to be installed on a wall of a building;
• and
• a second wall portion joined to the first wall portion, wherein the second wall portion extends in a second direction which is generally perpendicular to the first direction, and wherein the second wall portion is configured to overlay ends of cladding or an edge of the exterior insulation when the cladding and the exterior trim are installed on the wall of the building.

A method comprising:

• forming an exterior trim that is configured to be installed along a penetration in a wall of a building to overlay an edge of exterior insulation installed on the wall, wherein the exterior trim comprises a first protrusion extending from a body and a second protrusion extending from the body, and wherein the body is elongated;
• determining a thickness of the exterior insulation;
• determining a desired width of the second protrusion based on the thickness of the exterior insulation;
• and
• forming the second protrusion to the desired width.
