KIVIPUU is a completely non-toxic durable wood based on nature’s own fossilization process. This makes it extremely durable and fire safe. Fossilized wood patinates in the sunlight to a beautiful gray. It does not need care, so it is virtually maintenance free. The raw material used is selected Finnish pine, which is processed into high quality KIVIPUU.Due to its closed cell membrane, it is well suited for different seasons. KIVIPUU’s surface keeps moisture away, so it will not rot. In spring it is immediately ready for use without any maintenance. KIVIPUU is also manufactured with silicate surface treatment, which enhances its water-repellent properties. KIVIPUU stands up to the challenging conditions in Finland and all over the world.
