Although laminate flooring can be installed in multiple directions, there are two main ways that we can highlight: the perpendicular to the light, and the technique that depends on the longest distance.
The perpendicular-light option is a technique that depends on the direction in which the light enters the room, installing the boards parallel to the rays of that light:
The purpose of this installation technique is to hide any shadow that could be produced by some height difference between boards:
The second installation technique is the one that depends on the longest wall or distance in the area, that is, you have to determine which is the length that predominates in the room to be installed. In this direction, the boards are positioned parallel to the longest direction:
This type of installation is the most recommended, since it provides greater structural stability, since the forces are better distributed among all the boards.
In the case of laminate floorings, the expansion movements are greater along the board, and in this position, it reduces the sum of expansions, since there are fewer boards in the longest distance.
To put it bluntly, it is less likely to lift or rattle the flooring in the face of dilation.
In the corridors, the pieces must be installed longitudinally, never crosswise. In this orientation, maximize the structural stability of the installation in these areas:
It is possible that, once the direction of the rooms has been decided, in the corridors the flooring remains in a perpendicular orientation to their length. In this case, the direction can be changed just below the door frame, leaving an expansion joint or cut:
It is always important to define the flooring board orientation before starting to install, so as not to be surprised later.
