Corsica Mountains Collection — 6.5mm Herringbone SPC (Republic Floor)

The Corsica Mountains Collection is Republic Floor’s herringbone-pattern SPC line — individual 5″ x 30″ angle-cut planks that lock together in the classic chevron layout, for a more tailored, elevated look than straight-plank flooring. Each plank is a 6.5mm total SPC (Stone Polymer Core) build with a 20 mil wear layer and an attached acoustic EVA underlayment, joined with an angle-drop click-lock system that installs without glue or nails. The collection ships in 4 colors across a light-to-medium beige range, is FloorScore certified for indoor air quality, and carries a 50 Years Residential / 10 Years Commercial warranty. Corsica Mountains is available to order through our Santa Clara showroom.

Colors in the Corsica Mountains Collection

The Corsica Mountains Collection’s four colors — Bastia, Filitosa, Montane, and Rocca — stay within a light-to-medium beige range, so every option in the collection reads as a warm, neutral wood tone rather than a sharp contrast. That tight tonal range makes any of the four easy to run through an open floor plan without a jarring color break between rooms, while each color still carries enough of its own character to suit rooms with different light and cabinetry.

Best uses for Corsica Mountains Collection

• Kitchens & bathrooms — the SPC core is genuinely 100% waterproof with no time limit, so spills and splashes are never a risk to the subfloor.
• Basements & below-grade rooms — rated for above-grade, on-grade, and below-grade installation, one of the few flooring options that can go below grade.
• High-traffic, pet-friendly homes — the 20 mil wear layer and attached EVA pad stand up to daily foot and paw traffic.
• Rentals & multifamily units — the attached acoustic underlayment cuts impact sound transfer between floors, useful where HOA or condo noise rules apply.
• Radiant-heat floors — compatible with hydronic and embedded radiant systems as long as the surface temperature stays at or below 85 degrees F.

Choosing a color from the Corsica Mountains Collection

Since Bastia, Filitosa, Montane, and Rocca all sit within the same light-to-medium beige family, the choice comes down to how light or how warm you want the room to read rather than picking between contrasting looks. In a room with limited natural light or darker cabinetry, lean toward the lighter end of the range to keep the space feeling open; in a bright, sun-filled room, a slightly deeper tone can ground the space without darkening it. Because SPC color and grain can shift under different lighting, view a physical sample of each color at our Santa Clara showroom before you order.
