1 Structure: The laminated base and surface solid wood panel. Are end-to-end arranged for ordinary multi layer laminated solid flooring, for Yeyi multi layer laminated solid wood flooring, they are crisscross arranged, better against distortion and split in hot surroundings.

2 Back board: the general multi-layer parquet is directly compressed on the multi-layer materials without compressing the back board; The back of Yeyi parquet is pressed with a layer of backboard with the same thickness as that of the face board, in this way, the stress produced after the compression of single board on the face can be made fully even, so that the performance turns more stable and harder to avoid warping or deformation.

3 Raw material: general multi-layer parquet is mostly made of willow and eucalyptus; the raw material for Yeyi applies materials lighter than willow and eucalyptus, so that the veneer quality is better and the stability of the raw material get higher.

4 Groove: Due to the raw materials structure of the general multi-layer parquet the groove is very coarse; combination form of Yeyi raw material is different from them, it is as smooth as the solid floorboard on the straight stripe at the groove, which facilitates laying.

Yeyi multi-layer parquet include 12mm thickness and 15mm thickness, a simple suspension installation method can be implemented that is time and labor saving and can be laid on any ground with a terrestrial heat system
