The short boards are already prepared for herringbone laying (77° angle) and are therefore delivered with 50% tongue on the left side and 50% tongue on the right side. The herringbone floorboards are only available with fix dimensions.
Oak plank in 3-layer construction with small bevel on long side and approx. 4 mm top layer, with approx. 4 mm backing in the same wood and middle layer conifer. Tongue and groove on all sides for easy installation. The planks are free from knots and sapwood but have curled spots. Small knots and slight stress cracks are possible.
