• WALL TYPE IDENTIFICATION

Walls versus Partitions

• Walls

• 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

3
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.

Types of Walls
They are often built in this order.

• Load-Bearing Wall
• Non-Load-Bearing Wall
• Load-Bearing Partition
• Non-Load-Bearing Partition

A close look at the plate intersections will show
these walls are laid out differently.

Conclusions

• Walls are exterior, partitions are interior.
• Each may be load-bearing or non-load-bearing.
• Layout of centerlines and OC studs varies.
