At their simplest, mouldings hide and help weather seal natural joints produced in the framing process of building a structure. As decorative elements, they are a means of applying light- and dark-shaded stripes to a structural object without having to change the material or apply pigments

. Depending on their function they may be primarily a means of hiding or weather-sealing a joint, purely decorative, or some combination of the three.

Classical Mouldings
