How big should the edge/expansion joints be?
The total area of laminate flooring elements can change with changes in climate. It is therefore imperative that you allow for edge joints of at least 10 mm or more in accordance with the manufacturer’s/supplier’s specifications and subject to the area involved. There must always be a gap between the total floor unit created out of the individual laminate flooring elements and all fixed building components around it (walls, door frames, supply lines, pillars, etc.), i.e. an edge joint which provides sufficient leeway for the laminate flooring to move without coming into contact with those fixed building components.
