Bespoke: size, colour, finish

India wrote the grammar of the perforated wall: the jali has been filtering light, air and gazes for centuries. Bloc speaks that grammar with an Italian accent — Ronan and Erwan Bouroullec shape a hand-crafted extruded terracotta block, 13×13×10 centimetres with four round voids, and Mutina fires it in five colours, from raw Natural to glossy Pearl, Grey, Red and Blue. Stacked, it becomes a breathing screen; with Tube inserts, the voids take colour like inlay work.

The modern part is the paperwork: walls up to 4 metres with declared anchoring schemes, class C2 horizontal loads, dry installation on timber profiles with a solvent-free EC 1 plus sealant, and since 2025 an outdoor version rated F2 — severe exposure. For Indian offices and hospitality projects, La Mercanti delivers the jali instinct with Italian craft and documents to match.

FAQ

Why call Bloc a jali?
Because it does what a jali does: it divides while letting light, air and glances pass, dosed by the four voids in every block. The kinship is functional, not decorative — and the Italian contribution is craft terracotta in five colours with declared tolerances and anchoring schemes.
Does a breathing screen make sense in air-conditioned offices?
Especially there: the wall separates a reception or breakout zone without cutting daylight or sight lines, so the plan stays open while the functions stay distinct. Outdoors, the 2025 version carries frost class F2 for verandahs and courtyards.
How does the wall actually stand?
On declared engineering: up to 4 metres anchored on two sides, 4×3 metres on three, horizontal loads in class C2, always within local building regulations. Installation is dry — timber profiles and Mutina's solvent-free sealant — with the official video on mutina.it.
Is every block identical?
Deliberately not quite: production is artisanal and the real size is declared at ±3 millimetres, so the wall keeps the slight life of handwork — closer to carved stone screens than to injection-moulded panels. The module, though, stays constant at 13×13×10 centimetres.
What colours and accents are available?
Natural terracotta plus Pearl, Grey, Red and Blue in glossy or matt, with Tube inserts in red or blue to colour chosen voids indoors. One screen can mix finishes on a single module — quiet on one side of the room, jewelled where the brand needs it.

How to plan a screen wall the jali way

For Indian architects and workplace teams: using Bloc to zone lobbies, cafeterias and verandahs without losing air or light.

Map light and air first
Note where daylight enters and how air should move; place the screen where it filters both instead of fighting them.
Set heights from the schemes
Match your zoning to the declared limits — 4 m on two anchored sides, 4x3 m on three — and clear them with the structural consultant.
Choose the palette by room
Natural for calm circulation, glossy Red or Blue where the space hosts guests; the module never changes.
Reserve Tubes for emphasis
A few coloured inserts mark an entrance or reception axis indoors — and can be rearranged for the next season.
Plan the dry install
Timber profiles, EC 1 plus sealant, ribs aligned one way: a clean site, no mortar, and the mutina.it video for the crew.
