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.
