Premium Gypmaster 12mm Taper Edge Premium Gypsum Drywall Board

Gypmaster 12mm Taper Edge Premium Gypsum Drywall Board

The Gypmaster 12mm taper edge gypsum drywall board is a premium imported plasterboard built for internal drywall partition systems. It is the standard board thickness for drywall walling in South African residential and commercial construction, providing the rigidity, surface quality, and edge profile that drywall contractors and installers require.

This board is available in two lengths — 2700mm and 3000mm — both at a standard 1200mm width, so you can choose the size that best suits your partition height and minimises offcuts. Use the dropdown above to select your required length.

What Is the 12mm Taper Edge Gypsum Drywall Board Used For?

This 12mm board is designed for drywall partition walls and internal wall linings — the lightweight, steel-framed walling system widely used across South African homes, offices, retail spaces, and commercial interiors.

Drywall partitions built with 12mm gypsum board offer a fast, cost-effective alternative to conventional brick or block walls. They can be installed quickly, finished smoothly, and adapted easily to any interior layout.

The tapered edges along the long sides allow joint tape and compound to be applied flush with the board surface, resulting in a seamless, flat wall finish that is ready for painting or decorative plaster.

Typical applications include:

• Internal partition walls in residential homes
• Office and commercial interior partitioning
• Wall linings to existing masonry walls
• Retail, hospitality, and educational facility interiors
• Renovation and fit-out projects requiring fast, clean partition walls

Why Choose Gypmaster?

Gypmaster is FB Buildmart’s own premium imported gypsum board range, manufactured to international gypsum board standards. The 12mm board delivers greater thickness and impact resistance compared to thinner boards, making it well suited to high-traffic commercial areas and general residential drywall applications. Each sheet features a smooth ivory face paper that accepts paint and finishing plasters cleanly.

Because Gypmaster is imported under FB Buildmart’s own brand, we maintain consistent stock availability and quality control across batches — important when ordering boards for a full partition run where every sheet needs to match for a uniform finish. Offering both 2700mm and 3000mm lengths means contractors can select the option that best suits standard ceiling heights and minimises waste on larger commercial fit-outs.

12mm Taper Edge Gypsum Drywall Board: Available Sizes and Coverage

This board is available in two lengths. Coverage per sheet (single face) varies by length:

Length	Width	Coverage per Sheet
2700mm	1200mm	3.24m²
3000mm	1200mm	3.6m²

For a standard drywall partition, boards are fixed to both faces of the steel stud frame, so calculate your total wall area per face when ordering. Choosing the length closest to your partition height reduces offcuts and horizontal joints.

Practical Installation Notes

• Fix boards to steel stud and track framing using drywall screws at recommended centres
• Tapered edges must face outward at board joints — the recess accepts joint tape and compound for a flush finish
• For standard single-skin partitions, boards are fixed to 76mm or 89mm steel stud and track systems
• Stagger vertical board joints on opposite faces of the partition for improved rigidity
• For door openings, use appropriate steel or aluminium door frame kits
• Store boards flat, dry, and off the ground on level bearers — keep away from moisture at all times
• This is a standard board and is not moisture resistant — not suitable for wet areas or exterior use

For general installation guidance on drywall partition systems, the South African Building Interior Systems Association (SABISA) publishes industry guidelines worth consulting alongside manufacturer instructions.

Who Should Buy This Drywall Board?

This board suits:

• Drywall contractors and installers fitting out residential and commercial interiors
• Builders and main contractors on new residential and commercial builds
• Interior fit-out contractors working on offices, retail spaces, or hospitality projects
• Hardware stores and resellers supplying drywall partition materials
• Project managers and quantity surveyors specifying standard drywall board

If you’re quoting a partition wall run, it’s worth confirming your floor-to-ceiling height before ordering so you can select the length that minimises horizontal joints — 2700mm suits most standard residential ceiling heights, while 3000mm is often better suited to commercial spaces with higher ceilings. Our team can help you work out exact sheet quantities for double-sided partition runs.
