Properties of cork oak wood related to solid wood flooring performance

Application of cork oak wood as solid wood elements for flooring was experimentally assessed by measuring dimensional stability to air humidity and liquid water, response to loads applied while in service and abrasion due to people traffic using boards cut from the stem of five mature cork oak trees (Quercus suber L.). The results obtained from dimensional stability tests showed a performance of a medium movement in-service and small swelling in liquid water (2–3%). Hardness (55 N/mm2) and wear resistance allowed classifying cork oak wood as suitable for all domestic (including heavy traffic) and moderate commercial end-uses.
