The term molding is generally used to describe sawed timber that has been dressed or planed on all four sides.
Molding commonly involves adding profile to at least one side of a piece of timber.
In trade however, pieces that do not have any profile, but have been planed on all four sides (S4S) are also classified as moldings.
