Copperstone Gray

Copperstone Gray Natural Composite Flooring

A waterproof Forna Natural Composite floating floor that pairs natural ingredients with commercial class 33 durability. Copperstone Gray brings natural linseed composite, one of the original natural floor coverings, into a modern 3/8 in (9.5 mm) floating plank. The surface is made mostly from renewable raw materials: linseed oil, pine resin, limestone, cork wood flour, and jute. The result is a gray floor with genuine material depth rather than a printed imitation. Each plank is built in three layers: a 0.06 in (1.5 mm) natural linseed composite surface over a 0.27 in (6.8 mm) waterproof Hydrowood core, finished with a 0.05 in (1.2 mm) agglomerated cork backing. The core keeps the plank stable around moisture (24-hour swell under 1 percent), while the cork backing softens every step and cuts impact noise by roughly 18 dB. Underfoot it feels warmer and quieter than tile or laminate, and the HotCoating-protected surface carries a class 33 rating, so it is at home in busy hallways, kitchens, and commercial spaces alike. With a lightfastness rating above 7, the color holds up even in sun-drenched rooms. Planks click together with a Uniclic locking profile, so the floor floats over the subfloor with no glue or nails, and it is optimized for use over underfloor heating. Greenguard Gold certification confirms low emissions for healthier indoor air.
