Special parquet feathers in X-shape of 18mm are placed between the (floating) floor and the wall.
They keep the floor under tension so that seam formation is minimized. The parquet feathers are usually placed on the long side every 30 to 40 cm. In this case, the end faces of the floor parts have to be glued.
