Product Information

Full details

This guide is for builders and DIY enthusiasts working on projects requiring wall and ceiling linings, particularly in spaces where maneuverability is key. The primary benefit is its compact size, which aids handling and fixing in confined areas, while maintaining the dependable performance of standard plasterboard. A key consideration is that it is typically sold in bulk (e.g., a pallet of 80 boards), which is cost-effective but requires sufficient storage space and planning. This 12.5mm thick plasterboard features a tapered edge for seamless joint finishing, making it ideal for general drylining applications.

Extended Product Information

FAQs

What is the main advantage of the 1800mm x 900mm size?

The primary advantage is improved maneuverability and ease of handling, especially in confined spaces or during transportation to difficult-to-access areas.

What is a tapered edge used for?

The tapered edge creates a shallow recess at the board joints, which is designed to accommodate jointing tape and compound, allowing for a smooth, seamless finish once completed.

Is this board suitable for exterior use?

No, this is designed for internal drylining applications. It is not suitable for use in wet areas or exterior environments unless specifically treated or part of a system designed for such conditions.

What are the benefits of buying a pallet of 80 boards?

Buying in bulk significantly reduces the cost per unit, lowers transportation emissions, minimizes the risk of transit damage, and ensures a consistent supply of materials for larger projects, improving overall efficiency and profitability.

How thick is the plasterboard?

The plasterboard is 12.5mm thick, which is a standard industry thickness providing good strength and stability for general drylining.

Can I use this for soundproofing?

While plasterboard offers some inherent sound insulation properties, for enhanced soundproofing, consider using thicker boards, acoustic insulation within the wall cavity, or specialized soundproofing systems.

What is the best way to store these boards?

Store boards flat on a level surface, raised off the ground, in a dry, indoor environment. Avoid leaning them against walls for extended periods, as this can cause them to warp.

Troubleshooting

Board is difficult to cut cleanly

Ensure you are using a sharp scoring knife or a fine-tooth saw suitable for plasterboard. Score deeply and firmly before snapping.

Joints are not becoming seamless

Verify that the tapered edges are properly cleaned and free of debris. Ensure sufficient jointing compound is applied to fill the recess and feather out. Use a quality jointing tape and compound.

Surface cracking appears after finishing

Check that boards are adequately supported by framing and screws are correctly spaced and driven. Ensure adequate drying time between jointing compound applications and avoid rapid temperature changes.

Board feels unstable or flexes

Confirm that the framing is rigid and appropriately spaced for the board thickness. Ensure boards are securely fastened to the framing with the correct screw type and spacing.

Pros and Cons

Pros

Improved handling and maneuverability due to smaller size.
Cost-effective when purchased in bulk (pallet quantities).
Tapered edge facilitates easy and professional joint finishing.
Standard 12.5mm thickness offers good strength and durability.
Reduces CO2 emissions from transportation when bought in bulk.
Minimizes potential damage during transit when ordered as a pallet.

Cons

Requires significant storage space for bulk purchases.
May not be suitable for very large, uninterrupted wall sections where full-size boards could be faster to install.
Tapered edge finishing requires specific jointing techniques.
Bulk purchasing may involve a higher upfront cost compared to smaller quantities.

Setup, Compatibility & Care

Setup:

Ensure framing (timber or metal studs) is correctly spaced to support the 900mm width of the board.
Fix boards to the framing using appropriate drywall screws, spaced according to manufacturer guidelines (typically every 150-230mm along edges and 300-600mm in the field).
Cut boards to size using a scoring knife or fine-tooth saw. For precise cuts, a jigsaw may be used.
Apply jointing tape (paper or fiberglass mesh) to the tapered edges after the first layer of jointing compound.

Compatibility:

This plasterboard is compatible with standard timber and metal framing systems for walls and ceilings.

It is designed for use with Knauf jointing compounds and tapes for optimal performance.

Ensure all fixings and accessories are suitable for drywall applications.
