Overview

Nordic Oak Natural Composite Flooring

Forna Natural Composite on a waterproof core: a class 33 rated floor that stays quiet, warm, and colorfast. Nordic Oak brings a light, Scandinavian oak look to a material with real substance. The face is natural linseed composite surface, made mostly from renewable ingredients: linseed oil, pine resin, limestone, cork wood flour, and jute. It is a natural surface with UL GREENGUARD Gold certification for low emissions, so it supports healthier indoor air in your home or business. Each 3/8 inch (9.5 mm) plank is built in three layers: a 0.06 inch (1.5 mm) natural linseed composite top layer over a 0.27 inch (6.8 mm) waterproof Hydrowood core, finished underneath with a 0.05 inch (1.2 mm) agglomerated cork backing. That sandwich is why the floor swells less than 1 percent after 24 hours in water (EN 317) and still feels warmer and softer underfoot than tile or laminate. The natural linseed composite layer and pressed cork backing cut impact noise by roughly 18 dB, so footsteps and dropped items stay muted. A hardwearing polyurethane protection layer keeps the surface abrasion resistant under heavy use, and a lightfastness rating above 7 (ISO 105) means the color holds up even in sun-drenched rooms. Planks measure approximately 48.6 x 7.9 inches (1235 x 200 mm) and click together with a Uniclic locking profile: a floating installation with no glue and no nails. Rated commercial class 33 and domestic class 23, Nordic Oak fits busy households, offices, and retail spaces alike, and it is optimized for use over underfloor heating.

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 radiant (underfloor) heating?

Yes. Nordic Oak is optimized for use with underfloor heating systems, and its low thermal resistance of 0.09 m² K/W lets warmth pass through efficiently for added energy efficiency.

How does it handle water and spills?

The Hydrowood core is waterproof: tested to EN 317, the plank swells less than 1 percent after 24 hours of water exposure. Chemical resistance is rated very good (EN 423) and stain resistance grades 4-5 (EN 438-2), so everyday spills wipe up without leaving marks.

Will it stand up to a busy household or a commercial space?

Yes. It carries a commercial class 33 durability rating (EN 16511), is suitable for type W castor chairs (EN 425), resists impact to class 34 with a big-ball fall height of at least 71 inches (1800 mm), and shows no visible damage from furniture foot shift (EN 16581). Warranty coverage is 15 years residential and 5 years commercial.

How is it installed?

It floats: the planks click together with a Uniclic locking profile, no glue or nails needed, with joint locking strength above 650 kg per linear meter (ISO 24334). Each carton holds 7 planks covering 18.61 sq ft, and we recommend ordering 10 percent overage for cuts.
