PONT DE BATEAU

Strip made of foamed PVC with closed cells to absorb natural movements in the hardwood floor, see fig. 1.

The strip measures 3x8 mm (1/8" x 5/16") for 22 mm (7/8") floors and 3x4 mm (1/8" x 5/32") for 14 mm (9/16") floors and installed it provides a 2 mm (5/64'') wide joint, which varies over the year according to changes in the relative humidity.
We do not recommend shipsdecking for Glue Down System.

TWIN HERRINGBONE

Junckers' 14 mm (9/16") and 22 mm (7/8'') 2-strip floors are also available as patterned flooring. These floorboards are cut to a length of 516.6 mm (+/- 1.0 mm) (20 5/16") and are delivered in a right- and left-handed version. This enables installation in different patterns, e.g. herringbone. Each floorboard consists of two rows of staves. One row with a full length stave and one row with two half staves, see Fig. 2.

The Twin Herringbone flooring is delivered surface treated from the factory.
