MILLIMETER by Casanova · Natural stone

Redefiningnatural stone.

20 mm → 1 mm thick · ≈ 13 lb/ft² → 1 lb/ft²

Real marble, quartzite and travertine at 1 and 5 millimeters: up to 90% lighter, able to curve and to become furniture and architecture — and exactly the same stone.

The problem

For centuries, stone set the terms.

Too heavy for most structures. Slow and expensive to install. Impossible to curve. And every piece that reached the site could break before it was set.

Section at true relative scale Three stone pieces drawn in section at the same scale: a 20 mm traditional slab, a 5 mm MILLIMETER sheet and a 1 mm MILLIMETER sheet. 20 mm 5 mm 1 mm
  • Traditional slab 20 mm · ≈ 13 lb/ft²
  • MILLIMETER 5 mm · 3–4 lb/ft²
  • MILLIMETER 1 mm · ≈ 1 lb/ft²

MILLIMETER does not replace stone — it removes the thickness that was never doing any work. At 1 to 5 millimeters, stone stops being a structural constraint and becomes a design decision.

Applications

Eight places stone could not go before.

Each one exists for a concrete reason: weight, curvature or the absence of joints. They are not catalog ideas — they are consequences of the material.

Your application is not on the list?

It is probably still possible. The limit is set by the construction detail, and we review that with you before there is a quote.

Weight

The structure stops being the limit.

A square meter of 3/4 in marble weighs about as much as a small adult. The same square meter of 1 mm MILLIMETER weighs less than a laptop.

  • Traditional stone · 3/4 in (2 cm) 13–15 lb/ft² (63–73 kg/m²)
  • MILLIMETER · 5 mm 3–4 lb/ft² (15–20 kg/m²)
  • MILLIMETER · 1 mm < 1 lb/ft² (< 5 kg/m²)

Curvature

A real curve, not a cut.

  1. An arch or column clad in traditional stone is a sequence of flat pieces with joints the eye picks up.
  2. At 1 millimeter the stone follows the surface: the curve is continuous and the veining runs straight through it.
  3. That is the difference between a detail a client forgives and a detail a client remembers.
1 mm
tight curves, columns, arches, cabinet fronts
5 mm
demanding flat surfaces: countertops, integrated sinks

The exact minimum radius depends on the material and the piece. It is confirmed during the project study, before anything is produced.

Health & safety

Silica depends on the stone. Choose it knowingly.

Crystalline silica is why engineered quartz is linked to silicosis in the people who cut and install it. Natural stone is not automatically silica-free: the content depends on the rock. Marble and travertine contain little or none; granite and quartzite contain much more. We specify each stone with that in mind.

Typical crystalline silica content, by stone type

  • Marble & travertine Crystalline silica: < 5%
  • Granite Crystalline silica: 10–50%
  • Quartzite Crystalline silica: ≥ 95%
  • Engineered stone (quartz surfaces) Crystalline silica: < 0.2–95%
Natural stone available in MILLIMETER Engineered stone
  • Low-silica stones

    Marble and travertine contain little or no crystalline silica: under 5%.

  • Less material per cut

    A cut through 1 mm removes one twentieth of the material of a 2 cm slab; through 5 mm, a quarter.

  • Less work on site

    Pieces are prepared to the project drawings to keep cutting on site to a minimum.

  • Controls still apply

    With any stone, wet cutting, dust extraction and respiratory protection remain essential.

Carbon footprint

Less thickness, less footprint.

With 1 to 5 millimeters instead of 2 or 3 centimeters, every square foot weighs up to 90% less. We are mindful of our carbon footprint — and it starts with thickness.

Transport
Up to 90% less weight per square foot: lighter shipments and less energy to move them.
Packaging
Thinner, lighter pieces need less packaging material and take up less freight volume.
Lifting & handling
Less weight calls for lighter lifting equipment and anchors, in the shop and on site.
Material per square foot
One millimeter of stone covers what used to require two centimeters.

Casanova

A Legacy Shaped in Stone

90+years working with natural stone

Casanova represents more than 90 years and three generations of experience working with natural stone. What began as a family tradition in Spain has evolved into a design-driven company based in Houston, combining inherited craftsmanship with contemporary technology.

Led by CEO Jesús Casanova, the company approaches every project with a deep understanding of the material, from selecting stone at its source to developing, fabricating and installing custom architectural solutions.

How we work

From the idea to the installed piece.

  1. 01

    You send the project

    Plans, elevations, references or a photo of a sketch. Whatever you have.

  2. 02

    Technical study

    We define whether the material solves the piece, at what thickness and on what substrate. Everything is decided here.

  3. 03

    Material and quote

    Stone selected from real samples, cutting plan and a closed quote.

  4. 04

    Production and installation

    Custom fabrication and on-site support until the piece is in place.

If MILLIMETER is not the right material for your project, we will tell you. It is cheaper for everyone to find out on the drawing than on site.

Questions

What architects ask first.

What is MILLIMETER?

Real natural stone — marble, quartzite, travertine and granite — processed with a proprietary system down to a thickness of 1 to 5 millimeters. It is not a composite, a print or an imitation: it is the same stone, without the thickness.

How much does thin natural stone weigh?

MILLIMETER at 1 mm weighs under 1 lb/ft² (under 5 kg/m²) and at 5 mm about 3–4 lb/ft² (15–20 kg/m²). Traditional 3/4 in (2 cm) stone weighs 13–15 lb/ft² (63–73 kg/m²): between 73% and 93% more load on the structure.

Can natural stone really be curved?

Yes. At 1 mm the stone follows a curved surface in one continuous piece, so the veining runs through the curve without joints. Travertines and fine-veined marbles take tighter radii than quartzites; the exact minimum radius is confirmed during the project study.

Which thickness should I specify: 1 mm or 5 mm?

1 mm for tight curves, columns, arches and cabinet fronts. 5 mm for demanding flat surfaces such as feature walls, showers, doors, ceilings, countertops and integrated sinks. Many projects combine both.

Is it safer than engineered quartz?

It depends on the stone you choose, and we will not generalise. According to OSHA and NIOSH, marble and limestones such as travertine typically contain less than 5% crystalline silica, granite 10–50%, quartzite 95% or more, and engineered stone anywhere from under 0.2% to 95%, with conventional quartz surfaces at the top of that range. A MILLIMETER piece in marble or travertine therefore involves far less silica than conventional engineered quartz, and at 1 or 5 mm every cut removes a fraction of the material of a 2–3 cm slab. Whatever the stone, wet cutting, dust extraction and suitable protective equipment remain essential, and we confirm the technical data of the specific stone for each project.

Why choose MILLIMETER and natural stone over other materials?

Because it is the real stone: veining and tones that never repeat, the visual depth only a natural material has, and finishes worked by craftsmen — polished, honed or brushed surfaces, profiled edges, mouldings and mitred corners. Instead of a surface that imitates stone, MILLIMETER lets you work with authentic marble, quartzite or travertine at 1 and 5 mm, extending it to furniture, curves and architectural integration whenever the system and the chosen stone allow it.

How does it compare with engineered quartz and porcelain?

Each material has its place, so we stick to concrete differences. The resins in engineered quartz can be damaged, discolour or lose their sheen under high heat, so hot cookware needs a trivet. Porcelain is hard and stable, but its thin edges need care against impacts and are usually mitred or profiled. Natural stone can be repolished and its edges shaped, and every piece is unique; marble, in turn, is sensitive to acids and is sealed. We will tell you honestly which material suits your use, finish and budget.

Where are you based and where do you work?

MILLIMETER Global LLC is headquartered in Houston, Texas, with commercial presence in the United States, Spain, the United Arab Emirates and Colombia. Built projects include the Wittman Residence in Austin, the Altuve Residence in Houston and the Barret Project in San Diego. We work with architects, designers and private clients worldwide.

How do I get a quote?
