1. Price
The double-layer keel adds a layer of keel to the structure and Other auxiliary materials also increase the construction volume, so the price is slightly higher than that of a single-layer keel structure.
2. Installation sequence
The installation sequence (from bottom to top) of a single-layer keel structure is: leveling pad - elastic pad - wooden keel - subfloor - moisture-proof membrane - surface floor .
The installation sequence (from bottom to top) of the double-layer keel structure is: leveling pad— Bottom wooden keel (main keel) - elastic pad - upper wooden keel - rough floor - moisture-proof layer - surface floor.

Sports wooden flooring can provide an excellent sports experience, mainly The reason is in its structure. Compared with the single-layer keel structure, the double-layer keel structure has better buffering performance and is superior to the single-layer keel structure in terms of vibration absorption and resilience.
4. Structural advantages
It can be seen from the installation structure that the double layer The keel structure adds a layer of keel between the subfloor and the elastic pad, and the overall The increased height increases the distance between the subfloor and the ground, making the underlying structure of the wooden floor better ventilated and moisture-proof.
