A multi-part foundation ventilator. The ventilator has a first frame member with a first exterior peripheral edge flange, and, extending inwardly therefrom, a protruding wall portion of preselected width X.sub.1(A). The first inwardly protruding wall portion has an outer surface portion with a first receiving ledge portion and a protruding, first joining flange portion. A second frame member has a second inwardly protruding wall portion of preselected width X.sub.2(A). The second inwardly protruding wall portion further includes an outer surface portion, with a second receiving ledge portion and a second joining flange portion. The first joining flange portion of the first frame member is sized and shaped to fit in close fitting, overlying engagement with the second receiving ledge portion of the second frame member. The second joining flange portion of the second frame member is sized and shaped to fit in close fitting, overlying engagement with the first receiving ledge of the first frame member, so that the first frame member and the second frame member are securely joined in mating engagement at a sealed, substantially leafless joint therebetween.
