Can the hardwood floor be laid directly without a keel?

1. Disperse deformation stress: because the solid wood floor is a wood object arranged in the single fiber direction, which is very easy to deform, so the laying direction of the solid wood floor and the laying direction of the keel should be perpendicular when laying, and the purpose is to stagger the constraint to disperse the expansion and contraction stress of the solid wood floor.

2. Avoid moisture: solid wood flooring is easy to get damp, and hitting the keel can make the solid wood floor not directly contact the ground, have a certain air circulation, avoid the moisture of the ground directly into the floor, and prolong the life of the floor.

3. Fixed support: the deformation coefficient of solid wood floor is larger than that of solid wood floor, in order to reserve a certain expansion space for solid wood flooring, so the usual solid wood floor adopts flat buckle structure instead of lock structure, and the solid wood floor of flat buckle structure generally needs to be fixed on the keel with floor nails, and solid wood parquet usually uses a lock structure, without using nails to fix.

Writing here, I basically understand why the general solid wood floor is inseparable from the keel.

However, with the listing of some straight-laying solid wood floors, the market has some new public opinions: when laying solid wood floors, you can not hit the keel; Hardwood flooring can be laid directly on the underfloor heating; Since there is a solid wood floor that can be laid straight, there is no need to choose a solid wood floor with a keel.

It is better to lay the keel of the solid wood floor, because it can not only have a good sense of comfort, but also prolong the life of the floor. The role of the keel is mainly to stabilize the structure of the solid wood floor.

When the keel is paved with solid wood flooring, the direction is perpendicular to the direction of the floor, and the purpose is to stagger the constraints and prevent expansion and contraction. In the early days, the pavement of solid wood floors basically required keels, because the solid wood floor pure wood structure was susceptible to the influence of the environment and bulging and shrinking. The keel cannot be installed in a room with underfloor heating, and the keel paving can avoid the problem of floor noise.
