GREEN LIGNIN is suitable for floating installation, either in loose connection or with the new connection system in the form of a jigsaw puzzle. The chosen 1.8 mm standard thickness of the material makes installation far, far simpler. And the fact that GREEN LIGNIN is almost exactly the same thickness as standard commercially available transition strips makes it easy to overcome differences in height between multiple areas of flooring.
