Umber Cork Flooring
Warm umber browns, an 11 mm Swiss-made plank, and a Class 33 commercial rating: comfort that is built to take real traffic.
Umber blends warm browns with soft beige tones in an organic, gently varied pattern that reads like natural wood and stone at the same time. That subtle variation gives it rustic character without busyness, so it settles as easily into a cozy living room as it does a modern kitchen.
Under the surface, this is a serious floor. Each plank stacks a 3 mm genuine cork veneer over a 6.8 mm E1-grade moisture-resistant HDF core, finished with a 1.2 mm agglomerated cork backing for built-in insulation: 7/16 in (11 mm) of floor in total. The surface is sealed with a high-resistance, water-based polyurethane HotCoating, and the whole assembly is rated EN 16511 Class 33 for heavy commercial use.
Underfoot, cork's cellular structure does what no hard floor can: it absorbs sound, cushions each step, and eases foot and joint fatigue. With an R-value of 1.125, the floor stays warm in winter and cool in summer without extra insulation, and it pairs with hydronic radiant heat. Cork's natural suberin wax also resists mold, mildew, and pests, while the non-slip, gently compressive surface adds a margin of safety for kids, pets, and seniors.
Planks measure 35-15/16 in x 12 in (913 x 305 mm) with a clean square-edge profile. The Uniclic click-lock system pulls joints into a tight, watertight connection and floats across areas up to 50 ft x 30 ft without transition strips, which makes open-concept layouts, offices, studios, and basements all fair game.

I love the Umber Swiss Cork flooring. I ordered several different samples and I liked a lot of them, but the Umber stood out to me as my favorite. I like the randomness of the pattern, and the natural look of it.
My husband and I installed it ourselves. We had a little trouble getting started on second row. I think it was because to balance the edges of the room we cut the first boards in half and the narrower pieces coupled with our possibly not razor straight walls made the first row try to be a little bowed. This made getting the second row lined up straight a little tricky. We stuck with it and once we got the first row straight, the rest went together very easily.
