What is a Timber Stud Wall?

A timber stud wall is a lightweight internal wall built using vertical wooden studs and horizontal supports, usually covered with plasterboard. These walls are commonly used for dividing rooms, supporting fixtures, or concealing wiring and pipework. Unlike brick or block walls, stud walls are quicker to build, easier to modify, and more cost-effective.

Materials Needed to Build a Stud Wall

Before you begin, you’ll need the following materials and tools:

• Timber studs (typically 38mm x 63mm or 38mm x 89mm)

• Plasterboard (12.5mm thick is standard)

• Wood screws or nails

• Wall fixings (if attaching to masonry)

• Insulation (optional, for soundproofing)

• Tape measure and pencil

• Spirit level

• Saw (hand saw or circular saw)

• Drill and screwdriver

Stud Wall Spacing in the UK

Proper stud spacing is essential for structural integrity and ease of plasterboarding. In the UK, the standard spacing for vertical studs is 400mm or 600mm centre-to-centre (from the centre of one stud to the centre of the next). The choice between 400mm and 600mm spacing depends on:

• Plasterboard size – 1200mm wide plasterboard aligns well with 400mm spacing.

• Wall strength – 400mm spacing provides more rigidity and support.

• Insulation requirements – 600mm spacing can allow for larger insulation panels.

How to Build a Stud Wall

1. Plan and Mark Out the Wall

Decide where your wall will go and mark the positions on the floor, walls, and ceiling using a pencil and a spirit level.

2. Install the Top and Bottom Plates

Secure horizontal timber (top plate to the ceiling and bottom plate to the floor) using screws or masonry fixings.

3. Fix the Vertical Studs

Measure and cut the vertical studs to fit between the plates, spacing them at either 400mm or 600mm centres.

4. Add Noggins for Extra Support

Noggins (horizontal braces) help strengthen the structure and provide fixing points for plasterboard.

5. Attach Plasterboard

Fix plasterboard sheets to the frame using drywall screws, ensuring the joints land on the centre of a stud.

6. Finish and Decorate

Tape and plaster over joints, sand down any rough patches, then paint or decorate as desired.

Conclusion

Timber stud walls are a versatile and straightforward way to transform a space. By following proper spacing guidelines and construction methods, you can create a durable partition wall that meets UK building standards.
