|The ever-growing shortage of quality lumber is leading towards rationalization in its consumption. In parquet production, the tendency is seen as downsizing the production of solid parquet and developing pre-finished engineered parquet. Pre-finished parquet is an industry-made final wood product for flooring. Depending on the manufacturing technology, it can be made as two-layer parquet, three-layer parquet and multiple-layer parquet. Its surface layer is varnished and the strips are joined with tongue-and-groove. The surface layer is made of quality solid wood, is resistant to attrition, and has low thickness (much lower than solid parquet). The bottom or medium layer is made of small, softwood strips, veneer, plywood or MDF (HDF) boards. In this way, solid wood is used more rationally, supporting the positive physical and mechanical characteristics of parquet. A great advantage of pre-finished parquet, as opposed to solid parquet (especially solid, with tongue-and-groove), is rationalization in wood consumption, an easy and quick installment, without sanding and varnishing; a high level of aesthetics in design, and no need for trained professional installers.
