Wood floors need to be left in their packaging in the room in which they are going to be installed in order for the timber to adjust to the temperature, moisture and humidity of the room. This must be done before the floor is laid to reduce the possibility of the floor shrinking or expanding due to the change of atmosphere.The length of time flooring takes to acclimatize depends on various factors such as the species of wood, the size of the planks and the variance in atmospheric conditions. As a rough guide we advise leaving engineered wood floors to acclimatize for three to four days and solid wood floors for seven days – but the longer the better.
