What is the maximum floor length I can install without expansion joint?

The maximum floor length you can install without expansion joint mainly depends on two things:

  • the shape of the room in which the floor will be installed 
  • the climate conditions in that room

If the room is more or less square and if there aren’t too many indoor climate changes between weekdays and the weekend or during the day, then you can lay a surface of up to 10 metres long and 8 metres wide without extra expansion joints in the floor surface. With lengths of more than 10 m and widths of more than 8 m, there should be an intermediate expansion joint.

It is also recommended to foresee expansion joints under the doors between rooms to separate the rooms.
