WALL TYPE IDENTIFICATION Presentation 16: WALL TYPE IDENTIFICATION
Walls versus Partitions A general term for a vertical building component used to support loads and divide up living spaces Also a term used exclusively to describe exterior vertical surfaces Partitions Interior walls
Types of Walls Partitions and walls may each be load-bearing (LB) or non-load-bearing (NLB). With these combinations, there are four possible types of walls and partitions.

Virtual Construction A portion of a typically framed house.
Virtual Construction Construction begins on a floor system.

Virtual Construction These are exterior, thus they are walls.
Virtual Construction They are also load-bearing. LBW LBW

Virtual Construction This wall is exterior, but is not load-bearing. LBW LBW NLBW
Virtual Construction This is an interior wall (partition) and can be load-bearing. LBW LBP LBW NLBW
Virtual Construction The others are interior and non-load-bearing. NLBP LBW LBP LBW NLBW

Sole Plates A close look at the plate intersections will show these walls are laid out differently. (4) NLBP (3) LBP (2) NLBW (1) LBW
(1) LBW Plate Note that end of plate is also where the dimensions begin. OC Dimension to Centerline LBW NLBW
(2) NLBW Plate Note that end of plate is NOT where the dimensions begin. OC Dimension to Centerline LBW NLBW
(3) LBP Plate Note that end of plate is NOT where the dimensions begin. OC Dimension to Centerline LBP NLBW
(4) NLBP Plate Note that centerlines are not from end of plate, but OC may be. LBW OC Dimension to Centerline NLBP
Conclusions Walls are exterior, partitions are interior. Each may be load-bearing or non-load-bearing. Layout of centerlines and OC studs varies.
