A method for laying floor panels in a room to form a closed floor area on a laying plane (R) without using an adhesive. The floor panels especially comprising a wood material, such as MDF or HDF, and having matching corresponding profiles on opposite longitudinal edges (I, I′) and transverse edges (II, II′). The closed floor area is obtained by interconnecting a plurality of panels on their transverse edges (II, II′) to give a row (R1) and on their longitudinal edges (I,I′) to give a plurality of rows (Rn) and then locking them in relation to each other.
