Timber Partitions – Meaning of nogging in framed wooden partitions In a common framed wooden partition, what does the term “nogging” refer to?

Introduction / Context:
Timber partitions are built as frames of studs and rails with infill sheathing. Correctly naming members helps in detailing, communicating on site, and preparing accurate bills of quantities.

Given Data / Assumptions:

• Conventional stud-and-rail timber partition construction.
• Members include head, sill, studs, noggings (or blocking), and sometimes diagonal bracing.

Concept / Approach:
“Nogging” (also called blocking) is short, intermediate horizontal timber fixed between vertical studs. It stiffens the frame, supports fixings for services or sheathing, and prevents stud buckling. It is distinct from head and sill rails, which are continuous members at the top and bottom of the partition.

Step-by-Step Solution:
Identify the location: between studs, mid-height or at multiple levels.Identify the function: stiffening, fixing support, buckling restraint.Map the term “nogging” to these intermediate horizontals.

Verification / Alternative check:
Standard timber framing guides specify minimum spacing and fixing of noggings to meet service and fire-stopping requirements.

Why Other Options Are Wrong:

• Head and sill rails are continuous horizontals at the top and bottom respectively.
• Studs are the verticals; diagonal bracing is a different member used to resist racking.

Common Pitfalls:
Omitting noggings can lead to panel drumming and poor fixability for sockets or cabinets; placement should consider service routes.

Final Answer:
Intermediate horizontal member between studs
