Wineo Purline 1500 Herringbone - Ravenna Oak Nature PL15215WXSBio-PU

Herringbone: the zig-zag that never goes out of style. These are Wineo's wood XL designs cut into slim 48cm x 8cm planks, ready to be laid in classic herringbone, double or triple herringbone, basket weave and more. It's the parquet look that's been wowing people since the Romans - minus the gaps, creaks and sanding bills.

So what exactly is Bio-PU? It's a genuinely new kind of floor. Wineo's PURLINE is made from ecuran, a high-performance composite built mostly from renewable and natural raw materials - castor oil, rapeseed oil and good old chalk - bound with polyurethane. In other words, it's partly made of the stuff you'd find in a farmer's field and a school blackboard, and it's made in Germany by people who take floors very seriously indeed.

What it isn't: vinyl. There's no PVC, no chlorine, no plasticisers and no solvents in here, which also means no new-floor whiff - it's odour-neutral from day one. It isn't linoleum either: no linseed oil, no jute backing, no yellowish film to wait out after fitting and no sealing or polishing. Think of it as the cool cousin who skipped both family feuds and turned up with something better.

Don't let the castor oil fool you - this floor is tough as old boots. It's rated Class 23/34/43, so it's happy in heavy commercial and even light industrial spaces, and with residual indentation of just 0.10mm or less it shrugs off hospital beds, serving trolleys and wheelie suitcases. Office chairs too: 25,000 castor revolutions and not a mark.

It's kind to people as well as planets. You get an R9 slip rating with PTV 40+ in the wet, around 8dB impact sound reduction so classrooms and corridors sound calmer, and a surface that's warm and forgiving underfoot. It resists scratches, stains and UV fade, cleans up without harsh chemicals and is suitable for underfloor heating. The certificate shelf is heaving, too: Blue Angel, Greenguard, M1, Cradle to Cradle Bronze and an A+ indoor air rating.

Each box holds 40 planks at 48cm x 8cm - 1.54m², 2.5mm thick, for full glue-down installation. Herringbone needs a skilled fitter and a careful setting-out, so we recommend our nationwide fitting team. Minimum order is 20m².

Backed by Wineo's 20 year guarantee and made in Germany. Good news: this is one of the six herringbone colours Wineo keeps in stock, so it reaches you in around 10-12 working days.
