What did you have in mind?

Bespoke: size, colour, finish

The exposed brick is a national pride; its perforated cousin has always been hidden behind plaster. Bloc ends the embarrassment: Ronan and Erwan Bouroullec redesign the humble cored block as hand-crafted extruded terracotta, 13×13×10 centimetres with four round voids, glazed by Mutina in Pearl, Grey, Red and Blue or left raw as Natural. The Tube inserts slot colour into the holes — a wall you can punctuate like a sentence.

It builds properly, too: partitions up to 4 metres with declared anchoring schemes, horizontal-load class C2 on the data sheet, timber profiles and a solvent-free eco sealant instead of mortar, and an official installation video. Since 2025 the outdoor version carries frost class F2 — «severe exposure», in the norm's own words. La Mercanti specifies it where offices need division without darkness: receptions, meeting rooms, courtyards.

FAQ

Is Bloc a tile or a brick?
A brick — and proudly so. Ten centimetres deep with four through holes, it stands vertically as a building element and raises real partitions up to 4 metres, with anchoring schemes printed on the data sheet. This is ceramic that constructs a wall rather than dressing one.
How tall can a Bloc partition go?
Four metres anchored on two sides, four by three metres anchored on three, and 2.5 by 1 metres for low screens. Horizontal variable loads are declared in class C2, and the sheet defers to the building regulations of the country of use — numbers your structural engineer can actually work with.
Does it need mortar and a wet trade?
No. The system uses painted timber profiles at floor and ceiling — the top one with a removable frame — plus Mutina's organic, solvent-free sealant, rated EC 1 plus for emissions. Ribs face one consistent side, never up or down, and the official installation video on mutina.it walks the fitter through it.
What are the Tube inserts for?
Punctuation. The 2.5 by 10 centimetre terracotta cylinders in Red or Blue push into whichever holes you choose — a dot here, a rhythm there — and pull out just as easily, so the graphic stays reversible. They belong indoors; the outdoor data sheet does not include them.
What does the outdoor version actually change?
Frost class. Bloc outdoor, added in 2025, is rated F2 — «severe exposure» in the norm's own wording — while the 2021 indoor Bloc is F1 and for interiors only. Same format, same five colours, timber profile specified for exterior use: the screen wall steps into the garden unchanged.

How to divide a workplace without building a wall that blocks it

For architects and facility teams: sequencing a Bloc screen from reception filter to courtyard, with the data sheet doing the arguing.

Name what the screen must do
Privacy from the door, light for the room, air through the courtyard: the four holes dose all three — write the priority down first.
Fix heights against the anchoring schemes
Four metres on two anchored sides, 4x3 on three: hand the declared schemes to the engineer before the design falls in love with a dimension.
Choose raw or glazed
Natural terracotta absorbs attention quietly; glossy Pearl or Blue bounces daylight deeper into the plan — mix the two without changing module.
Punctuate with Tubes indoors
A scatter of red inserts on a blue field signs the wall; being removable, the graphic can change with the tenant, not against them.
Install dry, film in hand
Timber profiles, EC 1 plus sealant, ribs on one side: follow Mutina's installation video and the wall goes up without a wet trade.
