Do we really need expansion joints between every room?

A Quick-Step^® floor expands and contracts. The HDF core board is isotopic and expands and contracts in both the length and the width. This means it is extremely important to have expansion joints of 8 to 10 mm along all walls.

It is also recommended to put expansion joints under the doors between rooms and as such separate the rooms. If the Quick-Step^® floor is laid with a length of more than 10 running metres, from one room to another, across the corridor, etc., then this may lead to tension and possible distortion (upward warping) of the floor. This may occur when one room is heated and the other is not. Another possibility is to put a piece of heavy furniture in one of the rooms, etc. It is also recommended to separate some of the rooms from the rest by putting expansion joints under the doors between rooms.
