Putnam Lumber distributes sheathing by the bundle and by the truckload. Sheathing plywood is an economical choice for use in structural applications, such as a roof, floor, or wall. Rated Sheathing has designated Span Ratings for use in load-carrying applications. Rated Sheathing is graded for strength properties and is not graded for appearance since it is generally not exposed in final use. CDX has the same load-carrying Span Ratings, but calls for a C grade face veneer or better. Sheathing can be ordered both untreated or pressure treated for protection against wood destroying organisms.
