Do I really need expansion joints between every room?
Quick-Step Laminate floors expand and contract in function of changing relative humidity conditions in the room. The HDF core board is isotropic and works, equal in both length and width. This means it is extremely important to have expansion gaps of 8 to 10 mm along all walls, around radiator pipes, etc.
It is also recommended to foresee expansion gaps under the doors between rooms to separate them. Room humidity can vary according to the season, so it is vital that the floor is able to expand and contract. For this reason, make sure you leave an expansion gap on all sides of the floor, around pipes, thresholds and under doors.
This might occur when one room is heated and the other is not or when there is for example a piece of heavy furniture in one of the rooms. We therefore recommend separating some of the rooms from the rest by creating expansion gaps under the doors between rooms.
