The blank (100) has a frame (120) extending around circumference of the blank, and a core (110) surrounded by the frame, where sections of the frame are made from acetylated solid timber. The frame comprises longitudinal elements (122a-122e) that extend around the core and define the circumference, where the blank is designed in rectangular shape. The elements are arranged at an outer edge of the blank, and comprise longitudinal reinforcement elements (124a-124d) that are made from fiber-reinforced composite material, where an inner area of the reinforcement elements is free from the material. |
