CETRIS® PDB is a grinded cement-bonded particleboard with tongue and groove and smooth surface.
The cement-bonded particleboard of 1 250 x 625 mm (including the tongue) is calibrated by sanding and it is designed for dry flooring technology. The adjustment reduces thickness tolerance to +/- 0.3 mm. The following thicknesses are offered as standard: 16, 18, 20, 22, 24, 26, 28 mm. Upon the customer's request other thicknesses are available. There is a tongue and groove on the perimeter of the boards and they are to be laid over beams or used in restoration of floors.
