About Sioo 


Nature inspires us in everything we do and has made us who we are. With the help of nature and Swedish patented technology, we have created an ecologically sound wood-protection-system that gives durable, silver-grey wood surfaces. See how we and others have created pleasing and beautiful wood environments. Welcome to our beautiful, silver-grey world!
