Overview

Ashen Chestnut Cork Flooring

A light brown Swiss plank with a semi-matte wood emboss, built to commercial class 33 and quiet by 18 dB.

Ashen Chestnut wears a soft light brown tone with a wood-embossed, semi-matte surface, so it reads like timber underfoot while giving you everything cork does better: warmth, quiet, and give. Each plank is a generous 1235 mm x 200 mm (48 5/8 in x 7 7/8 in) at a substantial 11 mm (7/16 in) thick.

The construction is a true three-layer sandwich: a 3 mm cork top layer over a 6.8 mm E1 grade moisture-resistant HDF core, finished underneath with a 1.2 mm agglomerated cork backing that acts as a built-in underlay. The surface is sealed with HotCoating protection and a high-resistance Natural Shield water-based polyurethane finish, which is how a natural floor earns an AC5 abrasion rating.

Cork's honeycomb structure packs roughly 40 million air-filled cells into every cubic centimetre. That is what makes this floor permanently elastic, gentle on ankles, and warm enough for barefoot winters. It is bark, harvested without felling a single tree: cork oaks live up to 200 years and can be peeled up to 20 times.

Rated for on, above and below grade, compatible with hydronic and underfloor radiant heat, and made in Switzerland, it fits bedrooms and basements as readily as a busy storefront.

Why this floor

18 dB impact sound reduction (EN ISO 717-2), with a 1.2 mm agglomerated cork backing built into every plank.
Class 33 commercial and class 23 domestic usage rating (EN 16511) with AC5 abrasion resistance: storefront durability in a natural floor.
Watertight joints on a patented Uniclic click system; the HDF locking strength exceeds 500 kg per linear metre (ISO 24334), so joints stay closed for good.
Roughly 40 million cells per cm³ give real thermal insulation (thermal resistance 0.108 m²K/W): no cold feet, even in winter.
HotCoating surface protection plus a Natural Shield water-based polyurethane finish, backed by a 15-year residential warranty.
Low-emission build: E1 grade HDF core, emissions in conformity with AgBB, with GreenGuard Gold and formaldehyde test documentation below.
Radiant heat compatible (hydronic and underfloor systems) and rated for on, above and below grade installation.

Installation & care

Use this checklist to plan the project, then follow the linked product guide for the exact requirements.

Confirm that the subfloor is clean, dry, level and structurally sound; use a moisture barrier where the linked guide requires one.
Acclimate and inspect the material, mix planks from multiple cartons, and preserve every required perimeter and transition gap.
Sweep or vacuum grit and clean with a well-wrung damp cloth or mop—never leave standing water on the floor.

Common questions

Can I install this over in-floor radiant heat?

Yes. Ashen Chestnut is compatible with hydronic and underfloor radiant heating systems.

Is it suitable for a basement?

Yes. It is rated for on, above and below grade installation. The core is 6.8 mm E1 grade moisture-resistant HDF, the Uniclic joints are watertight, and 24-hour swelling tests under EN 317 come in below 8%.

Will it stand up to pets and heavy traffic?

Yes. The floor carries a commercial class 33 rating with AC5 abrasion resistance, is tested suitable for type W castor chairs, and the HotCoating surface protection keeps it hard-wearing for years. Residential use is covered by a 15-year wear warranty.

How is it installed?

As a floating floor with the patented Uniclic click-lock system: no glue or nails. Use a taping block for precise, damage-free locking, and order about 10% extra for cutting waste. Each carton covers 15.95 sq ft with 6 planks.
