Sisam manufactures full-body porcelain and ceramic surfaces for floor, wall, and outdoor installations. Six collections. One uncompromising standard.
Soft-glaze porcelain — a satin-matte surface engineered to diffuse interior light. Available in 600×1200 and 1200×2400 mm.
For five decades Sisam has produced ceramic surfaces from a single facility in Castellón, with kilns we maintain ourselves and clay we source within 200 kilometres. Our engineers and ceramists work the same floor, every day. The result is a tile we can stand behind, mm by mm.
Each collection is engineered for a use case — light diffusion, slip resistance, large-format continuity. Hover to fan the stack; click any panel to focus.
A few of the numbers that define a Sisam tile — the rest are in the technical sheet.
Manufactured from a single facility in Castellón. No outsourcing, no white-label — every tile leaves through one loading bay.
Embodied carbon vs. 2018 baseline.
Six-millimetre slab — book-matched panels, no joint within a 5 m wall.
“A tile is a quiet object.
It should outlast the argument that put it on the wall.”
Every Sisam tile is verified against international ceramic standards — and our own, which are tighter.
Below 0.5% threshold for full porcelain — frost-safe, stain-safe, exterior-grade.
Outdoor and wet-area slip rating across the Riva collection, certified at three independent labs.
Breaking strength for 12 mm slabs — exceeds EN 14411 by 38%.
Standard structural warranty; 25-year on Stratos large-format with certified installer.
Our clay, feldspar, and kaolin all originate within a single drive of the kiln. We capture 100% of process water, recycle press-edge waste back into the body, and run the kilns on a hybrid biomethane–electric mix. The result is an EPD that holds up under any audit.
“The shortest supply chain is also the most honest one.”
A vertical record of how a Sisam tile is made. Scroll the right column; the left tracks your position.
Clay, feldspar, and kaolin sourced within a 200-km radius of the kiln. Each batch is tested for moisture, plasticity, and oxide composition before it enters the line.
Wet-milled to a controlled particle distribution. Spray-dried into atomized powder with consistent moisture content — the foundation of dimensional accuracy at firing.
Hydraulic presses up to 26 000 t form the green tile. Pressure-modulated dies introduce the textures and reliefs that define collections like Onda.
Digital decoration combined with hand-tuned glaze stations. Up to 12 colour passes per tile, fixed in real time against a master reference.
Vitrification at 1230°C in roller kilns running on a hybrid biomethane–electric mix. The firing curve is logged per tile and archived for 10 years.
Every tile passes through dimensional, planarity, and tonal sorting. Statistical samples are pulled to the lab for absorption, breaking strength, and slip testing.
