Cuzi Particle Board Tubular Hollow Core Particle Board is produced via continuous horizontal extrusion presses. Precision longitudinal tubular voids reduce core weight by up to 60% compared to solid timber, while providing superior compressive resistance (up to 2.0 MPa) and sound transmission reduction (Rw 28 to 34 dB) for interior commercial flush doors.
