Created with great respect to the environment, and made with real wood from responsibly managed forests, these Strong Wood floors find their extraordinary strength through tried-and-true BerryAlloc innovations such as Ultimtec – a solvent-free, ultra-resistant and extra-matt varnish; and a locking system that’s extra-easy to install. The high impact resistance linked to the high density fiberboard core and the high abrasion resistance of the Ultimtec lacquer confers a very high strength to the floor.
