DOOR FRAME HAVING DURABLE WOOD PORTIONS

摘要

A frame for doors, windows, and the like of buildings includes upper and lower portions that are both made of wood. The upper portion of the frame is made of a conventional wood, and at least a portion of the lower portion of the frame is made of a wood that is naturally resistant to weathering, decay, rot, insects, or the like. According to other aspects of the present invention, other building components such as doors, trim, and the like may also be constructed utilizing different wood species for different parts of the component to provide different levels of rot and/or decay resistance for different parts of the component.
