Dimensions, location and the work you need.
01 / Understand the construction
Drywall partitioning is a lightweight way to divide internal space using a frame lined with gypsum plasterboard. The partitions discussed here are non-load-bearing: they create rooms rather than support the building above.
A typical wall uses galvanised steel studs and tracks, boards on both sides, and cavity insulation where the design calls for it. Doors, services and the final finish need to be planned with those materials.
The board type, thickness and layers must match the intended wall system.
The framework is selected for the wall height, openings and required performance.
Suitable insulation fits between the studs and forms part of the acoustic or thermal design.
Compatible jointing, perimeter seals and service details complete the construction.
02 / Start with the room
A storeroom, bedroom and confidential meeting room can call for very different wall constructions.
For passages, dressing rooms, storerooms and internal layout changes, begin with the wall height, openings and intended use.
Plan early: door positions, services and the desired finish.
Discuss acoustic expectations before selecting the boards and insulation. Speech privacy needs attention to the entire separation between rooms.
Plan early: cavity fill, board layers, doors and ceiling connections.
Suitable moisture-resistant boards can form part of a specified internal system. Direct water exposure and tiled wet areas require their own detailing.
Plan early: the exposure, board specification and waterproofing requirements.
Use an identified, tested wall construction where a fire rating is required. Board, framing, insulation and service penetrations must match that system.
Plan early: the required rating and complete manufacturer specification.
Tell the installer about tall partitions, large doors, televisions, cupboards and shelving before boarding begins. Stud size, steel gauge, spacing and reinforcement need to suit the job; the same frame will not suit every application.
03 / Build your material enquiry
Start with the specified wall construction. Then confirm the exact products, thicknesses, quantities and supply options.

GYPSUM PLASTERBOARD
Our 3000mm regular gypsum board listing is a starting point for an interior project that specifies this product. Confirm its suitability for your wall construction before ordering.
Check the whole specification. A matching thickness does not make different board types interchangeable in a tested system.
View the 12.5mm board ↗
ISOVER
Glasswool products developed for framed construction and drywall cavities. Discuss batts or cavity rolls according to the wall layout and specified insulation.
Thickness options to discuss: 63mm and 102mm. Isover lists the thicker option as 102mm; match it to the actual cavity and system.
Explore cavity insulation ↗
KNAUF INSULATION
Glass mineral wool designed for internal wall and floor applications. It provides sound absorption within a suitable partition construction.
Thickness options to discuss: 63mm and 100mm. Request Acoustic Roll by name so it is distinguished from the general ceiling roll range.
Explore acoustic rolls ↗Gyproc RhinoBoard
RhinoBoard is a Gyproc plasterboard brand, with standard and specialist board options. We are preparing to add RhinoBoard to our range. If your project specifies it, ask us to confirm the exact product and availability before ordering. Standard RhinoBoard, FireStop and MoistureResistant boards serve different specifications.
Include the specified steel section, gauge, track, anchors and screw requirements in the enquiry. The framing schedule must allow for wall height, openings and connections.
Ask about compatible joint tape, jointing compound, corner treatment, perimeter details and any specified skim finish. Include these in the material schedule from the start.
If Energylite or another specialist product is specified, send the density, thickness and system reference. Higher density alone does not guarantee better sound isolation.
Ask us to confirm availability of framing, specialist boards and finishing accessories. For a tested wall, specify every component by its approved product name.
04 / Plan acoustic privacy
Cavity insulation absorbs sound energy inside the partition. The amount of sound passing between rooms depends on the combined construction and its connections.
A roll’s sound-absorption figure is not the wall’s sound-reduction rating. For a specified acoustic result, work from the tested wall system and consider the building around it.
Compare acoustic insulation optionsBoard mass, layers, stud arrangement and insulation work together. Fit the specified insulation without avoidable gaps or forcing an oversized product into a shallow cavity.
Sound can travel through adjoining construction or over a partition via a ceiling void. Plan the head of the wall and surrounding connections, especially for private offices and boardrooms.
Door gaps, glazing and poorly detailed penetrations can undermine privacy. Coordinate electrical boxes, services and seals before the cavity is closed.
05 / Compare the options
Both can be appropriate. Compare the complete construction, the required performance and the disruption to the building.
| Consideration | Drywall partitioning | Brick or masonry wall |
|---|---|---|
| Weight & construction | Lightweight framed construction with comparatively little wet work. | Heavier construction requiring suitable support and wet trades. |
| Future alterations | Often practical for office changes and adaptable internal layouts. | Alterations generally involve more demolition and making good. |
| Acoustic privacy | Depends on the specified boards, framing, insulation and junctions. | Mass can help, but openings, connections and flanking paths still matter. |
| Services & fixtures | Services can run in the cavity. Heavy fixtures need suitable support and fixings. | Services may need chasing. Fixings must suit the masonry and load. |
| Project cost | Varies with height, layers, insulation, openings and finish. | Include wall construction, plastering, drying, services and finishing. |
A single price per square metre cannot describe every wall. A basic divider and a specified acoustic or fire-rated partition have different material and labour requirements.
Ask whether a rate measures one face of the partition, both boarded faces, or a complete installed wall. Then compare the inclusions on the same basis.
Ask your quotation to identify
06 / A useful starting point
Enter the total length of walls that share the same height. The planner separates partition area from board lining on both sides and insulation within one cavity.
You can still ask for help. Send a few photographs, your location and what you want the partition to achieve.
This is an area estimate, not a board cutting schedule, structural design or installed price. Door reveals, returns and additional surfaces need separate measurement. Board quantities, pack rounding and framing must be checked for the final layout.
From the plan to the finish
A clear sequence helps the installer, other trades and the customer agree on what is included.
Confirm the layout, height, room use, performance requirements and finish. Identify any system reference in the specification.
Set out doors, services and reinforcement with the framing. Confirm fixing provisions for heavy items before the boards go on.
Install the specified cavity insulation, board layers and connection details, with services and openings properly coordinated.
Complete the required joint treatment and trims. Allow the specified drying and preparation before painting or decoration.

Cape Town & surrounding areas

Common questions
Use these answers to prepare your enquiry. Where drawings specify a particular wall system, that specification remains the starting point.
Ask about your project12.5mm plasterboard is used in many internal partition systems, but board thickness alone is not a specification. Confirm the product, frame, layers, wall height and intended use. Thin ceiling boards should not be substituted into a partition simply because they cost less.
RhinoBoard is Gyproc’s plasterboard brand. Gypsum board is the broader material description. Different brands and specialist board types have different specifications; use the exact product required by a tested or specified wall system.
No. It provides sound absorption within the cavity, but privacy depends on the complete partition, doors, openings and surrounding construction. Discuss the required acoustic result before the system is chosen.
Only where the particular product is suitable for the cavity and permitted by the wall specification. Purpose-designed products such as Cavitybatt, Cavitylite and Knauf Acoustic Roll provide clear options to discuss. Check thickness, fit and the system requirements.
A suitable system can be used in appropriate locations. Moisture-resistant plasterboard is not a substitute for a complete wet-area design. Confirm the board, exposure, waterproofing and tile support details, particularly around showers and direct water contact.
No. The required resistance applies to the specified complete assembly, including framing, board layers, joints, openings and penetrations. Use the relevant manufacturer-tested system and its installation details.
Suitable fixings and support can be planned for the load. Provide the position and weight of heavy items before boarding so the installer can include the required reinforcement or fixing provisions.
No. Compare the completed work: materials, labour, access, services, openings and decoration. A high-performance drywall system can cost more than a basic wall. Check that competing quotations describe the same requirements and measurement basis.
It depends on the area, wall height, openings, site access, services and finish. Jointing and decoration also need appropriate drying time. Ask for a programme based on your actual project.
