Lunawood Thermowood is an outstanding material for façades, thanks to its remarkable dimensional stability, weather resistance, durability and beautiful appearance. Lunawood does not necessarily require surface treatment even in the most challenging climate, which makes it a truly sustainable choice throughout its life cycle. Untreated surface turns beautifully silver grey over time, when exposed to UV-light. Lunawood claddings and battens have a beautiful uniform brown tone, which can be retained by protecting the wood with a pigmented and UV-protected surface treatment.
