Knauf Drywall Plasterboard - Tapered Edge - 2400 x 1200 x 15mm

The metallised polyester foil acts as a vapour control layer, preventing moisture from migrating from the warm interior side into the building structure, which helps to avoid condensation and damp.

No, this product is designed for internal applications only. It provides vapour control from the interior side of external walls, not protection against external weather.

No, the plasterboard is designed to be easily scored and snapped using a standard Stanley knife and a straight edge. No specialized cutting tools are required.

It is ideal for loft conversions, the internal faces of external walls, and pitched roof installations where effective moisture and vapour control are critical.

The tapered edge is designed to create a slight recess when boards are placed edge-to-edge, allowing for seamless jointing with jointing compounds and tape, leading to a professional, smooth finish.

Yes, it complies with BS1230 Part 1 1985 standards, ensuring it meets requirements for quality and safety in building applications.

The dimensions are 2400 x 1200 x 15mm.

Ensure your utility knife blade is sharp. Make a deep score line on the front face and snap with firm, even pressure. For thicker boards, a second pass may be required.

Minor nicks can be repaired with appropriate vapour-permeable tape. Significant damage may require the board to be replaced in that section to maintain vapour control.

Ensure tapered edges are clean and free of debris before applying jointing compound. Use appropriate jointing tape and multiple thin coats of compound for a smooth finish.

Verify that all joints, edges, and penetrations (e.g., around pipes, cables, light fittings) have been effectively sealed to maintain the integrity of the vapour barrier. Check ventilation in the room.
