Trade terms for professionals and design studios

London interiors have spent a decade falling for reeded surfaces — fluted joinery, ribbed glass, batten walls. Rombini takes that instinct and fires it: Ronan and Erwan Bouroullec read the rhombus as a three-dimensional profile, so the wall becomes a run of slender ceramic battens that hold their line for decades, not a veneer that dents at the first office move.

Each batten is pressed in a dedicated 3D mould, glazed and mounted on mesh in three scales — Extra Small at 16 mm thick, Small and Large at 22 — with five matt colours, three gloss and two crackle glazes, Vert and Brun. Terminal pieces and a glazed-edge Listello finish edges and corners properly, and the mesh lets the surface follow a curve. The collection took the Archiproducts Design Award in 2016.

Stain resistance sits at class 5 under ISO 10545, two classes above the requirement, so a boardroom wall stays a boardroom wall. La Mercanti supplies Rombini with real sample batches — their cost fully credited on order confirmation — because a reeded wall should be judged by hand, not by screen.

FAQ

How do the three Rombini Triangle sizes differ?
Extra Small runs eight 2 cm battens per sheet at 16 mm thick — a fine, dense rib. Small and Large climb to 22 mm with wider battens, five and three per sheet, so the shadow gets deeper. Same profile, three scales: you are choosing how strong the relief reads across the room.
Should I pick matt, gloss or crackle for an office wall?
Matt colours absorb harsh lighting and suit large, bright spaces. The three gloss glazes bounce light and wake up compact rooms. Vert and Brun add a crackle texture with the patina of historic glazed ware — they simply ask for cementitious grout and no acid cleaners.
How is a Rombini wall cleaned in daily office life?
Gently: no abrasive pads, especially on gloss finishes, and no acid or limescale removers on the crackle glazes. The glaze itself does the hard work — ISO 10545 stain resistance is class 5, the top grade, against the class 3 the standard requires.
What finishes the edges of a reeded ceramic wall?
Two purpose-made pieces: the Terminal, a shaped closing profile in all colours, and the Listello, a 9×31.5 strip with one glazed edge for corners. One Small Terminal pairs with seven Small battens, so edges are designed rather than improvised.
When was Rombini designed, and has it been recognised?
Ronan and Erwan Bouroullec drew the collection in 2015 and refined it in 2021; the Triangle series won the Archiproducts Design Award in 2016. Its pedigree shows in the details — a dedicated 3D pressing mould and trim pieces for every colour.

Specifying a reeded ceramic wall that lasts

Five practical calls that turn the reeded-wall trend into a permanent piece of architecture, from profile choice to edge details.

Test the profile against the light
Reeding lives on shadow. Check where daylight and fittings actually hit the wall: raking light rewards the Large profile, flat frontal light suits the fine Extra Small rib.
Choose glaze by duty, not by mood
Matt for big daylit walls, gloss where the room needs lift, crackle Vert or Brun where you want patina. Note the one rule the datasheet is strict about: no epoxy grout on the crackle glazes.
Draw the edges before the order
Decide now where the wall stops: Terminal pieces close horizontal runs, the glazed-edge Listello turns corners. Their modularity is fixed — one Small Terminal to seven battens — so the drawing settles the quantities.
Order a hand sample, not a render
A reeded surface is judged by touch and raking light. Sample costs are fully credited on order confirmation, which makes the physical check an easy decision.
Brief the installer on the sheet logic
Flat, dry walls, non-rapid adhesive, joints matching those inside the mesh sheet, grout worked in small areas and washed before it sets. A tidy sheet layout is what keeps the battens reading as one surface.
