The board undergoes minimal expansion and swelling under high humidity conditions and is suitable for load-bearing applications in humid conditions. Naturspan HS can be refined with paper, melamine, veneer or laminate. The board is easy to mill and has low formaldehyde emission. Natural wood has values of < 2 mg/100 g dry substance; Naturspan HS achieves the same low emission levels. The board is free of isocyanates and phenol glues.
