Wall Panel 21T Walnut: matching the tone and counting packs

Walnut is a hard tone to buy from a photograph. It shifts with the light, it reads warmer or greyer depending on what is next to it, and two walnut finishes from different groups rarely sit together quietly. So before anything else, treat Wall Panel 21T in walnut as a colour decision with a measuring job attached, rather than the other way round.

The plank, the pack, the area

• Face width of one plank: 30cm
• Length: 240cm
• Thickness: 1.2cm
• Planks in a pack: 8
• Area a pack covers: 5.76m²

Those figures are from the listing, which gives the panel as 30 x 240 x 1.2cm without saying which number does which job. The 240cm in the product name fixes the length, and the remaining pair follow. Lined up side by side, eight planks reach 2.4 metres across at a full 2.4 metre height, which is where the 5.76m² comes from.

The count is in units of 30cm, so a 2.7 metre wall wants nine planks and therefore two packs, with seven to spare. A 3.3 metre wall wants eleven. At 4.5 metres you need fifteen, so two packs leaves you one plank in hand, and a 5.4 metre wall needs eighteen and a third pack. Spare planks are not waste on a wall like this, incidentally: a damaged one is far easier to replace from the same batch than to match later.

Judging a walnut tone honestly

If there is already walnut in the room, in a floor, a worktop or a sideboard, hold the decision until you can compare them properly. A screen flattens the difference and warm artificial light hides it. The listing names the finish and nothing further, so if the exact tone is load-bearing for the scheme, ask the shop whether a sample or a close photograph can be sent, and look at it against the room at the time of day the room is actually used.

Seamless planks or acoustic panels

This plank is sold on its tongue-and-groove joints, which the listing says close up without visible gaps. The alternative in the same tone name is an acoustic panel such as Wall Panel 01T in walnut. Neither listing describes its face profile in words, and neither quotes a slat width, so that comparison has to be made from the photographs rather than the descriptions. What this listing does commit to is the practical side: it calls these PVC panels and says they suit areas where moisture resistance and easy maintenance matter, which points them at a hallway, a utility room or a bathroom wall more than at a bedroom.

The joint, and the ends you will see

The description puts the tongue-and-groove joint at the centre of this panel, and says it is there to close the gap between planks. What it does not describe is which edges carry the profile, so ask before planning a join along the length of a plank rather than between two of them. The outside edges are a separate question: wherever the panelling stops short of a corner, a door or a window, something has to cap it. The strips in panel trims and fittings do that job, and the shop can confirm which profile suits a 1.2cm panel. Wall panel adhesive is sold on its own, so check it against your wall surface before you add it.

What this listing leaves open

Two things, and both are reasonable to ask about. The description calls the panels PVC and in the same breath describes three-sided oak veneer, so the face of a walnut panel in a PVC group needs confirming rather than assuming. And nothing is said about the sheen of the finish, which on a wood tone changes how much of the grain you read from across the room. Neither is a reason to avoid the panel; both are reasons to put one question to the shop before the order goes in.

What it sits with

Walnut recurs across the panelling range, so a scheme can be carried from one wall to another: Wall Panel 82T in walnut is another seamless walnut panel, twelve pieces to a pack, and Wall Panel 81B in walnut comes sixteen to a pack. Neither of those plank widths is quoted here, so read each listing rather than assuming they line up with this one. Everything in the group is listed under slat and acoustic panels. Delivery is free within 50 miles of the Glasgow store and £50 beyond it.

Once the tone is settled and the plank count is on paper, order Wall Panel 21T walnut seamless for the whole wall in one go so every plank comes from the same batch.
