Where flexible clay cladding is being used

On an elevation the deciding factor is usually weight. A 25mm stone rainscreen brings 55–65 kg per square metre plus a support frame, which on a retrofit often means the structure has to be checked and sometimes strengthened before a single slab is hung.

At roughly 4.5 kg per square metre the same elevation adds less than a tenth of that, bonded directly to a rendered or plastered substrate with no frame and no mechanical fixing. On a high-rise, the Level A1 fire classification and the absence of any panel that could work loose and fall are the two points that usually matter to the consultant.

This is the application the material exists for. Cladding a circular column in stone means either a bespoke curved section cut on a CNC, or a faceted approximation with a visible mitre every 150mm. Both are expensive and both look like a compromise.

A flexible sheet wraps the column. The texture runs continuously around the radius, the joint falls on the back where nobody sees it, and the whole thing is done in an afternoon. Vertical textures like Ripple Stone and Liner Stone curve best because the corrugation absorbs the compression on the inner face.

Joinery is where stone stops being an option entirely. A wardrobe shutter faced in 20mm marble is too heavy for its hinges, too thick for its carcass and too brittle to survive being opened four times a day for a decade.

A 3mm sheet bonded to ply or MDF gives a shutter with a genuine mineral face at a weight ordinary hardware carries. The same applies to island facings, bar fronts, headboards and reception desks — and because the sheet wraps an edge instead of needing a mitre, the return on a cabinet end has no visible joint.

Institutional work is specified by people who have to live with the building for thirty years. That changes the priorities: the Level A1 non-combustible classification clears the fire strategy on corridors and escape routes, and the fungus and algae resistance matters on a campus where nobody is going to pressure-wash a north elevation every monsoon.

The practical arguments are just as decisive. Large elevations go up fast with no wet trade and no scaffolding for a support frame, which matters when the work has to happen between terms. And because the finish is a manufactured shade code rather than a quarry batch, phase two matches phase one even if it is built three years later.

Retail runs to a fit-out calendar measured in days, in malls that often ban wet cutting and slurry entirely. Anything that needs a diamond blade and a water feed is a scheduling problem before it is a cost problem.

This cuts with a knife, goes on with adhesive, and produces no dust and no slurry. On a rollout, the other advantage is repeatability: the same shade code delivers the same wall in Bengaluru and in Chennai, which natural stone from a working quarry cannot promise.
