The country house plank type Alm, glued as a 3-layer parquet, lives from the characteristics and wood features of oak. The symmetrical structure prevents cross warping in the event of temporary unfavourable climatic conditions. With the all-round tongue and groove system, the plank is suitable for full-surface gluing on standardised subfloors. The 3-layer structure minimises natural swelling and shrinkage. The wear layer thickness of 4 mm enables renovation, similar to solid parquet.
