Knauf Soundshield Plus Tapered Edge Plasterboard - 2700mm x 1200mm - 12.5mm

This specific product is 2700mm long, 1200mm wide, and 12.5mm thick with a tapered edge.

The 2700mm length reduces or eliminates horizontal joints in standard-height rooms, leading to faster installation and a more uniform finish.

While it offers good durability, for areas with high moisture like bathrooms and showers, a dedicated moisture-resistant plasterboard (e.g., aquapanel) is recommended. This board is more suited for dry internal partitions and linings.

The tapered edge creates a recess that should be filled with jointing tape and multiple layers of jointing compound, feathered out evenly to blend with the board surface.

The product description indicates it offers reliable fire performance, but specific fire ratings (e.g., Euroclass) should be confirmed with technical data sheets for precise applications.

Yes, the 12.5mm thickness and its acoustic and fire properties make it suitable for suspended ceilings and linings in noise-sensitive environments.

Use drywall screws specifically designed for plasterboard installation, suitable for either timber or metal framing depending on your structure.

Ensure the scoring line is deep enough and the board is snapped cleanly over the edge. Use a sharp blade.

Adjust screw gun depth setting to embed the screw head just below the paper surface without breaking it. Do not over-tighten.

Ensure sufficient jointing compound was used and feathered out properly. Apply an additional thin coat if necessary, ensuring it is well-blended.

Verify that all joints are properly sealed, and there are no gaps around openings (e.g., electrical boxes, windows). Ensure the board is installed correctly to the framing.
