DuraPatina is a maintenance-free wooden façade. The maintenance-free nature is based on an oxidative process and prevents an uneven appearance over the years, whether in weathered or non-weathered areas. The façade is available in all technically feasible profiles. There are five colour shades, which correspond to the natural greying tones. New is a non-visible installation for vertical and horizontal mounting. DuraNatur characterises the natural colour tone of the wood. A special oil-based pigmentation significantly delays the greying of the wood. The wood is highly water-repellent and protected against surface fungus. New colour shades have been developed due to the high demand.
