Our Nautilus Laminate is constructed with a premium black spruce core to provide a denser and more dimensionally stable laminate floor. The black spruce core provides water resistance for up to 72 hours, as well as allowing for rooms as large as 66' x 66' (4,000 square feet) with no transition or expansion moldings required. Nautilus comes in a 5" standard width plank or a 7.5" wide width plank. Some colors are available in standard and some in wide. Nautilus is easy to clean, including wet mopping. It is also easy to install. Nautilus utilizes the drop lock installation system and comes with a premium pad attached.
