Lignum Core Flooring

What Is Lignum Core Flooring?

Lignum Core is a multi-layer vinyl floor designed for rooms where real wood or laminate would struggle. A high-definition printed decor sits under a clear wear layer and a polyurethane surface coating. The grain is embossed to follow the print so oak planks feel like timber rather than a flat picture. Underneath, the build depends on the version you choose: a rigid stone polymer composite (SPC) board for the click floor, or a flexible vinyl layer for the glue down floor.

Lignum lists every Core floor as 100% waterproof, stain resistant and protected against micro-scratches. The surface is also antibacterial. That makes the range a practical choice for kitchens, bathrooms, utility rooms and busy homes with children or pets, while still giving the warm oak and natural stone looks people want in living spaces.

Lignum Core Rigid Vinyl (SPC Click)

Lignum Core Rigid Vinyl is the click version. Each plank or tile has a rigid SPC core with a 1mm IXPE acoustic underlay bonded to the back, giving a total thickness of 5mm for planks and herringbone and 5.5mm for tiles. The boards lock together and float over the subfloor without adhesive, so the floor can usually go down in a day and be walked on straight away.

The plank and herringbone designs have a 0.5mm wear layer and the stone tiles have 0.55mm. Lignum’s technical data puts the rigid range at Class 23 for heavy domestic use and Class 31 for moderate commercial use. It has an R10 slip rating, a Bfl-s1 fire rating and a 21dB impact sound reduction from the attached underlay. It is phthalate-free, rated E1 for formaldehyde and A+ for indoor air quality.

Planks measure 1220 x 180mm (2.64 sq m per pack), herringbone blocks 610 x 122mm (2.23 sq m per pack) and tiles 610 x 305mm (2.23 sq m per pack). For a wider choice of click floors see our click LVT collection.

Lignum Core LVT Dryback (Glue Down)

Lignum Core LVT Dryback is the traditional glue down version. At 2.5mm thick it is fixed to a prepared subfloor with flooring adhesive, which gives a solid, quiet floor that sits tight to the screed and suits large open-plan areas and conservatories where a floating floor would need extra expansion breaks. A slim 2.5mm floor also keeps the finished height low against existing thresholds and doors.

Every dryback design has a 0.5mm wear layer under a three-in-one UV polyurethane coating, an embossed-in-register surface and painted bevelled edges. The core is made from 100% virgin vinyl and the range has an R10 slip rating. Planks measure 1227 x 187mm (3.67 sq m per pack), herringbone 590 x 118mm (3.2 sq m per pack) and tiles 609.6 x 304.8mm (3.72 sq m per pack). Browse more options in our glue down LVT range.

Rigid Vinyl or Dryback: Which Lignum Core Should You Choose?

Both versions share the same decors, wear layer and guarantee. The difference is how they are built and fitted.

As a rule of thumb, choose rigid vinyl if you want a quick floating floor or plan to fit it yourself. Choose dryback if you want the most solid finish over a well-prepared subfloor or a single floor running through a big open-plan space. Our guide to glue down vs click LVT covers the trade-offs in more detail and our SPC flooring guide explains how rigid cores work.

Lignum Core Herringbone

Herringbone is the most searched part of the Lignum Core range. It is available in every oak shade in both constructions. The rigid vinyl herringbone uses 610 x 122mm blocks that click together. Each pack holds 15 left and 15 right blocks marked A and B so a parquet floor can be laid without glue. The dryback herringbone uses slightly smaller 590 x 118mm blocks that are glued down in the traditional way, which suits fitters who want full control over the pattern and borders.

Either way you get the look of a laid oak parquet floor that is waterproof, warm underfoot and far easier to look after than real wood. Compare it with other designs in our herringbone LVT collection or read our herringbone flooring guide.

Lignum Core Colours and Designs

The oak decors run from light to dark, so there is a Lignum Core floor for most schemes:

• Light oak: Seashell Oak and Linen Oak, for bright, Scandinavian-style rooms. See more light LVT.
• Natural and warm oak: Barley Oak, Sahara Oak, Ranch Oak and Rustic Ember Oak. Their honey and brown tones suit almost any interior. See more natural LVT.
• Grey oak: Rustic Grey Oak in both versions, plus Greywood Oak in the dryback range. See more grey LVT.
• Dark oak: Truffle Oak and Mocha Oak, for rich, dramatic floors in larger rooms. See more dark LVT.
• Marble and slate tiles: Carrara White Marble Matt, Ivory Marble, Beige Slate, Light Grey Slate and Charcoal Slate, for kitchens, bathrooms and hallways. See more stone effect LVT tiles.

Colours vary between screens, so we recommend previewing your shortlist with the AI room visualiser on each product page before you order.

Is Lignum Core Waterproof?

Yes. Both Lignum Core versions are 100% waterproof, so spills, splashes and wet footprints will not swell or damage the floor. That makes the range a good fit for kitchens, bathrooms, utility rooms and hallways. The R10 slip rating adds grip. The stain-resistant, scratch-protected surface copes well with pets and family life. A sweep or vacuum and a damp mop with a pH-neutral cleaner is all the routine care it needs.

Lignum Core is also suitable for underfloor heating. Lignum’s installation guidance for the rigid range sets a maximum subfloor temperature of 27 degrees C. The heating should be brought up gradually after fitting. Read more in our guide to the best flooring for underfloor heating.

Lignum Core vs Lignum Fusion

The two Lignum collections are easy to confuse but are very different floors. Lignum Fusion is a 12mm AC4 laminate with an HDF core: solid and warm underfoot, but not waterproof, so it is best kept to dry living spaces. Lignum Core is vinyl: thinner, fully waterproof and suited to every room including kitchens and bathrooms. If you love a Lignum oak look but need it to handle water, Core is the one to choose. Browse the laminate side in our Lignum Fusion laminate range.

Installing Lignum Core

Lignum Core Rigid Vinyl is a floating floor, so it must not be glued or fixed down. Lignum asks for a 10 to 12mm expansion gap around the room edge and an expansion joint where the floor runs more than 8m in length or width or crosses between heated and unheated areas. The subfloor must be flat and sound; carpet, cushion vinyl and other floating floors need lifting first. The dryback version needs a smooth, level subfloor and the right adhesive, so it is usually fitted by a professional. If you would rather leave it to us, our LVT fitting service covers Greater Manchester and Cheshire.
