Grano

Grano Cork Flooring

A white-toned cork plank with soft beige-brown undertones, a whisper-quiet 18 dB of impact sound reduction (ΔLw, EN ISO 717-2), and a click-together build you can float over any grade of your home. Grano is a stained cork floating floor made in Portugal, the heart of the cork industry. Its white surface sits over natural cork, letting a fine, organic grain and warm beige-brown hues show through. The result is a bright, versatile floor that pairs as easily with a modern condo as it does with a traditional family home. Each 900 mm x 300 mm (35 7/16 in x 12 in) plank is a full 10 mm (25/64 in) thick: a 3 mm genuine cork wear surface over a 6 mm E1 class high density fiberboard core, with a 1 mm cork underlay already attached underneath. That sandwich is what gives cork its signature feel: resilient and warm underfoot, with excellent acoustic insulation built into every plank. The surface is sealed with a high resistance Natural Shield water-based polyurethane. It is a durable, low-VOC, stain resistant finish that protects against daily wear while preserving cork's natural texture and breathability. With the Uniclic click lock profile, planks simply angle and lock together: no glue, no nails, and a realistic weekend project for a confident DIYer. Rated for above grade, on grade, and below grade installation, and compatible with hydronic and underfloor radiant heating, Grano fits living rooms, bedrooms, offices, basements, and any space where warmth and quiet matter most.

Important product note

Grano has a white surface over natural cork, so shade variation between planks may be noticeable. This is a natural feature of cork, and it is part of the character of a stained white cork floor: order all your cartons together and blend planks from several boxes during installation for the most even look.
