SHIPSDECKING
Strip made of foamed PVC with closed cells to absorb natural movements in the hardwood floor, see fig. 1.
The strip measures 3x8 mm and installed it provides a 2 mm wide joint, which varies over the year according to changes in the relative humidity.
We do not recommend shipsdecking for Glue Down System.

WHALEBONE / HERRINGBONE PLANKS
Junckers plank floors are also available as patterned floors. This means that the floorboards are cut to fixed lengths and are delivered in a right- and left-handed version. This enables installation in different patterns, e.g. herringbone. Whalebone is delivered surface treated from the factory.
