The theory that heat can be used to improve the resistance of wood to decay has been around for thousands of years. In the 1920's scientists began to make a concerted effort to put this theory into practice. It was in the late '90s that a real breakthrough was made in thermally modifying wood on an industrial scale, and for more than ten years now Stellac has been sharing its unique process world-wide. The reliability of Stellac® technology and its process control systems ensure that every single batch of Stellac®Wood meets the highest quality specifications. By overseeing the whole project from start to finish - design, construction, commissioning, training, TMT quality control, and support services-Stellac ensures that the product always meets customers' expectations.
