19mm Knauf Coreboard Square Edge Plasterboard 3000mm x 600mm

High-density gypsum coreboard, measuring 3000 × 600mm, developed as the core layer for Knauf Shaftwall and other multi-board fire-rated systems.The square edge design ensures precise, close-fitting joints, maintaining the integrity of complex wall build-ups.Each sheet covers 1.8m² and weighs 29.52kg, providing a durable and dimensionally stable solution for demanding shaftwall and service riser applications.Faced with an ivory paper liner, the board is intended for concealed use within layered systems, where its density enhances both fire performance and acoustic separation.A thermal conductivity of 0.19 W/mK enables its inclusion within system U-value calculations, supporting regulatory compliance.
