Ashen Chestnut

Ashen Chestnut Cork Flooring

A cool, ash-toned chestnut plank with a watertight Uniclic click system, built to a commercial class 33 rating and quiet underfoot at 18 dB impact sound reduction.

Ashen Chestnut takes the familiar warmth of chestnut wood and mutes it with a soft, ashen gray cast, giving you a calm, contemporary floor that pairs as easily with modern interiors as with traditional rooms. It is a full 7/16 in. (11 mm) floating plank made from natural cork, harvested from the bark of the cork oak without damaging or felling a single tree.

The construction is a three-layer sandwich: a 0.12 in. (3 mm) natural cork top layer over a 0.27 in. (6.8 mm) E1-grade moisture-resistant HDF core, finished underneath with a 0.05 in. (1.2 mm) agglomerated cork backing. The surface is sealed with HotCoating protection and a high-resistance Natural Shield water-based polyurethane finish, which is how this floor earns class 33 for commercial spaces and class 23 for homes.

Underfoot, cork’s honeycomb cell structure (roughly 40 million cells per cubic centimeter) does two things at once: it insulates, so the floor stays comfortable year-round and winter mornings barefoot no longer mean cold feet, and it stays permanently elastic, cushioning every step and going easy on your ankles.

The click joint is the quiet standout. The patented Uniclic profile locks planks into a highly secure, watertight joint that surpasses standard click versions, eliminating open seams and adding stability. You install it floating, no glue and no nails, using an 8 in. (20 cm) taping block to protect the plank edges.

Why this floor

• Rated class 33 commercial and class 23 domestic (EN 16511), with a 15-year residential and 5-year commercial warranty.
• 18 dB impact sound reduction (EN ISO 717-2), thanks to cork’s honeycomb cell structure and the agglomerated cork backing layer.
• Watertight patented Uniclic joints: locking strength above 500 kg per linear meter (ISO 24334) and 24-hour edge swelling under 8% (EN 317).
• HotCoating surface protection with AC5 abrasion resistance (EN 14354 and EN 13329), suitable for type W castor chairs.
• Natural thermal insulation from about 40 million air-filled cells per cubic centimeter, with a thermal resistance of 0.108 m² K/W.
• Low-emission build: GreenGuard Gold certified, in conformity with AgBB emission requirements, on an E1-grade HDF core.
• Permanently elastic natural cork wear surface that is gentle on joints and lightfast to 7/8 on the ISO 105 scale.

Common questions

Can I install this in a busy household with pets and heavy foot traffic?

Yes. This plank carries a commercial class 33 rating with AC5 abrasion resistance, so it is built for traffic well beyond a typical home (domestic class 23). The HotCoating surface protection resists wear, it is rated suitable for type W castor chairs, and residual indentation is limited to 0.15 mm, so it recovers from everyday pressure. It is covered by a 15-year residential warranty.

How does it handle spills and moisture?

The patented Uniclic joint locks watertight, which eliminates open seams where liquid could creep in, and the core is E1-grade moisture-resistant HDF. In the 24-hour swell test (EN 317) the plank stays under 8% swelling. Tight, sealed joints plus the water-based polyurethane top finish give you time to wipe up spills before they become a problem.

How is it installed?

It floats: planks click together with the Uniclic locking profile, no glue or nails. The watertight joint is tighter than standard click systems, so plan to use an 8 in. (20 cm) taping block to seat the planks; that protects the edges and keeps the joints damage-free. Order about 10% extra to cover cuts, with each carton covering 15.95 sq ft in 6 planks.

Will it actually feel warmer and quieter than hardwood or laminate?

That is cork’s signature. Around 40 million air-filled cells per cubic centimeter give the floor a thermal resistance of 0.108 m² K/W, so it holds a comfortable temperature year-round, even barefoot in winter. The same cell structure absorbs impact sound (18 dB reduction) and stays permanently elastic, so footsteps feel cushioned and rooms sound noticeably calmer.

Important product note

This floor uses an adapted Uniclic click system that locks watertight and exceeds European standards, surpassing standard click versions by eliminating open joints and improving stability and wear resistance. The trade-off is a snugger fit during installation: use an 8 in. (20 cm) taping block to tap planks together. It takes a little extra effort but guarantees precision, prevents edge damage, and keeps the floor looking pristine.
