1. UNDERSTANDING MATHIOS STONE
Mathios Stone is a sustainable reconstructed stone veneer made from natural selected aggregates, cement, and mineral pigments.
It is lightweight, durable, frost-resistant, non-combustible, fire-resistant, breathable (i.e. also relatively resistant to mold) – ideal for both interior and exterior applications on any surface, including installation directly over insulation systems (ETICS).
What sets Mathios Stone apart is the combination of authentic stone aesthetics with the technical advantages of a sustainably manufactured product, with a 30-year guarantee, developed by a company with over 140 years of expertise in materials and masonry.
The result is a system that combines cultural heritage, efficiency, and design freedom — without the environmental impact of quarrying.
Mathios Stone is handmade and not quarried like traditional stone, but it is most natural in its material composition. It is crafted using mineral pigments — the same minerals found naturally in stone. It is designed to replicate the depth, irregularity, and warmth of traditional stone — while solving many of its structural and practical limitations.
In short, it delivers the authentic experience of stone in a form that’s more practical in its installation and adaptable.
Each stone is handmade, created by artfully casting molds of selected pieces of quarried stone. A mix of cement, lightweight natural aggregates, and mineral oxide-based pigments is poured into these molds, then cured to create pieces that are visually and texturally true to stone.
The manufacturing process is tightly controlled, ensuring consistent quality, structural integrity, and long-lasting color — while eliminating the waste and emissions of traditional quarrying.
Mathios Stone is composed of:
- Cement – for strength and durability
- Natural lightweight aggregates – for reduced weight and thermal behavior
- Mineral oxide pigments – for deep, weather-resistant coloration
- Proven legacy: Developed by Mathios Refractories, a fifth-generation company with over 140 years of expertise in advanced materials.

2. QUARRIED STONE VS. RECONSTRUCTED STONE
Mathios Stone offers the visual depth, texture, and timeless appeal of quarried stone — without its weight, installation challenges, or environmental footprint.
Where quarried stone is heavy, rigid, not breathable, and often requires structural support, Mathios Stone is lightweight, breathable (not friendly to fungi), precisely shaped, and designed to install cleanly on a wide range of substrates — including over thermal insulation systems. It’s also available in a huge collection of styles and colors that match — or in many cases, surpasses the aesthetic of traditional quarried stone walls, as it also surpasses geographical constraints.
Mathios Stone gives you the beauty of traditional stone with the flexibility of a made-to-measure solution. With over 250 distinct textures and colors — and the ability to create thousands of custom combinations — Mathios offers “stone with a barcode.” Like tailoring a suit for your home, you can order the exact quantity, texture, color, and format you need, in short delivery times even for large-scale projects.
Unlike quarried stone, which may vary from batch to batch or become unavailable over time, Mathios Stone designs remain repeatable and traceable — ideal for future extensions, renovations, or additions years later.
It also brings key practical advantages:
- Lower installation costs — typically 2 to 3 times cheaper than quarried stone
- Consistent sizing for faster, cleaner application
- Lightweight — ideal for installation over thermal insulation
- Far lower environmental impact — with no destructive quarrying and no harm to local ecosystems or communities
Mathios Stone doesn’t imitate stone — it evolves it.
Installing quarried stone is a labor-intensive process that requires heavy machinery, mortar beds, and often the expertise of traditional stonemasons — professionals who are increasingly rare in modern construction. Each stone must be cut, shaped, and set by hand, making the process slow, costly, and difficult to scale.
Mathios Stone is engineered for efficiency without compromise:
- It comes in pre-shaped, lightweight individual pieces
- Each piece is designed to be glued like a tile using certified adhesives
- Corners are premade for a natural look and super fast installation.
- It installs easily on standard surfaces — including over insulation — without needing structural reinforcements
- The overall installation process is typically up to 5x faster than quarried stone, with significantly lower labor and equipment costs
In today’s construction landscape — where time, budgets, and skilled artisans are in short supply — Mathios Stone offers a smart, scalable solution that preserves the beauty of traditional masonry while embracing modern building realities.
While Mathios Stone is highly versatile, it is not load-bearing and should not be used in applications where the stone itself must support structural loads. It is also not intended for continuous submersion in water (e.g., pools, fountains).
That said, when installed properly as a cladding system, Mathios Stone offers long-term durability even in demanding exterior environments — including high elevations, freeze-thaw cycles, and coastal humidity.
Yes — and in many ways, it’s more sustainable than quarried stone.
Mathios Stone avoids the destructive footprint of traditional quarrying:
- ZERO blasting. The lightweight aggregates are all excavated from large zero-blast quarries which are required to rehabilitate the mined, according to strict European regulations, unlike small unregulated stone mines.
- No destruction of natural terrain and disruption of local ecosystems, communities, villages etc.
- No long-haul transportation of heavy stone blocks
- It is produced in controlled European facilities using natural aggregates, cement, and inorganic mineral pigments — with minimal waste, lower emissions, and responsible sourcing.
- Mathios Stone is 100% recyclable — it contains no organic materials, and can be broken down and reused
- All packaging is made from recycled cardboard and is fully recyclable
- It is VOC A+ rated, ensuring zero air pollution or off-gassing indoors
- It is compatible with ETICS (external thermal insulation systems) — making it the only responsible way to achieve stone design on energy-efficient façades.
In short, Mathios Stone offers the only environmentally sound solution for combining stone aesthetics with thermal performance — a true bridge between beauty and sustainability.
Yes — Mathios Stone is an ideal material for restorations, renovations, and projects in culturally sensitive or historic environments.
Many of its stone profiles are inspired by centuries-old regional styles, including Mediterranean fieldstones, Cycladic dry stacks, and European masonry traditions. The textures, tones, and irregular edges are designed to reflect the natural aging, craftsmanship, and depth found in traditional stonework.
Because it is modular, lightweight, and repeatable, it allows architects to:
- Match existing façades with precision
- Recreate historic details that are otherwise unavailable or unaffordable in quarried stone
- Avoid heavy structural reinforcements in old or delicate buildings
Mathios Stone provides the aesthetic and emotional continuity needed in restoration work, while also offering modern installation speed, safety, and compliance.
Whether you’re restoring a village home, updating a historic hotel, or extending a listed property, Mathios Stone lets you build with respect for the past and confidence in the future.
3. COLOR, TEXTURE & STYLE
No. Mathios Stone uses permanent mineral oxide pigments that are absorbed during the curing process, becoming part of the material itself. This ensures long-lasting, UV-stable color that resists fading — even in harsh outdoor environments.
Slight variations in color and surface texture are a natural and intentional part of Mathios Stone. Each piece is handcrafted to ensure a unique, non-repetitive appearance that reflects the irregular beauty of quarried stone. The general tone and color proportions of each model are maintained, but small differences will always be present — and they’re part of what gives Mathios Stone its authenticity.
Additionally, due to the rough surface structure and broad color palette, stones can appear very differently depending on lighting and viewing angle. The color of the same stone wall may look totally different under different lighting conditions or photographed from different angles. For this reason, we always recommend evaluating real physical samples rather than relying on photos, as images can be misleading. Only a physical sample can give you a true sense of how the stone will behave in your space.
Yes. With over 250 color and texture combinations, Mathios Stone is designed for creative mixing and custom blends. Many designers and architects mix series or shades to match regional stone styles or to create entirely new visual identities. Custom projects are welcome and supported.
Color is added by hand, using mineral oxide pigments, which are blended into the stone mix and sometimes layered onto the surface during molding. These pigments are then locked in during the curing phase, ensuring natural tone depth and long-term color integrity. This handmade method ensures no stone will be the same, as in nature.
Absolutely. Many Mathios models are inspired by regional stone styles — from Mediterranean fieldstones to Alpine ledgers and Cycladic dry-stack walls. Whether you’re restoring a historic façade or designing a home in a specific vernacular style, there is likely a Mathios profile that captures the character you’re looking for.
What is the difference between the Slim Series and the Standard Series (e.g., Isola Slim vs. Isola)?
The Slim Series is designed for applications where space and weight constraints are critical. With a thinner profile (typically below 30 mm) and lighter weight, it is ideal for installations over thermal insulation systems or in areas with limited space. Despite its reduced thickness, the Slim Series maintains the authentic appearance and texture of natural stone.
In contrast, the Standard Series features thicker and heavier stone veneers, offering a more pronounced depth and shadow effect due to greater variation between high and low points. The choice comes down to project-specific needs and aesthetic preferences.
4. INSTALLATION & SUBSTRATES
Mathios Stone can be installed on a wide variety of surfaces, including concrete, cement board, masonry, brick, and properly prepared insulation systems. The surface must be clean, structurally sound, and free of dust or contaminants. With the right preparation, Mathios Stone adapts easily to both interior and exterior walls, curved surfaces, and architectural features.
Yes — this is one of Mathios Stone’s key advantages. Its lightweight construction makes it ideal for installation over external thermal insulation systems (ETICS), such as EPS or mineral wool. This allows for seamless combination of aesthetic cladding and energy efficiency, without additional structural load.
No. Because Mathios Stone is a non-load-bearing veneer, it does not require a support ledge or foundation footing. It is installed directly onto the substrate using adhesives and mortars, which are tested for vertical applications. This makes installation faster, easier, and more flexible than with quarried stone.
For best results, use only certified tile adhesives and flexible grouts suitable for exterior or interior stone veneer applications. Mathios offers recommended adhesives and mortars developed specifically for our stone systems. The use of correct materials ensures proper bonding, long-term performance, and weather resistance.
While Mathios Stone is easier to install than quarried stone, proper installation is still essential for a long-lasting and beautiful result. Experienced DIYers may install it successfully, but we always recommend using a trained or certified professional, especially for exterior walls, curved surfaces, or thermal insulation systems.
Yes. Installation should be avoided during extreme temperatures (below 5°C or above 35°C), or on wet, dusty, or unstable surfaces. Ensure that expansion joints, corners, and substrate transitions are handled properly, and that surfaces are completely cured and prepared according to our guidelines.
Mathios provides detailed installation manuals, technical sheets, and project-specific guidance. We also offer access to trained installers and partners with expertise in stone veneer systems. Asking your installer to follow our documentation — or contacting us directly for support — is the best way to guarantee a professional result.
5. DURABILITY & PERFORMANCE
Mathios Stone offers a limited warranty of over 30 years, but its actual lifespan is much longer. Because it is made from the same mineral ingredients as quarried stone — simply reconstructed into a more efficient form — it shares the same essential durability.
Like natural stone, Mathios Stone does not expire. It is designed to age gracefully, resist weathering, and retain its structure and color over time. When installed correctly, it performs for decades or generations, just like the traditional stone walls that inspired it.
Yes. Mathios Stone is engineered to withstand freeze-thaw cycles, making it suitable for use in cold climates and alpine regions. Its composition of lightweight aggregates and cement minimizes water absorption and prevents cracking or surface damage caused by freezing moisture.
Yes. Mathios Stone is non-combustible and suitable for use in areas requiring fire-resistant cladding. It does not contribute to flame spread and is safe for use around fireplaces, chimneys, and other heat-producing elements when installed with proper backing materials.
Mathios Stone itself is not a waterproof barrier — it must be installed over a waterproof or water-managed substrate (such as concrete, insulation with WRB, or cement board). Like all cladding systems, it is designed to breathe and allow moisture to escape, preventing buildup and mold.
Yes. Mathios Stone is designed to perform in a wide range of climates, including heavy rain, snow, coastal humidity, high UV exposure, and temperature extremes. When installed correctly, it retains its color, texture, and structural integrity over decades of exposure.
Yes. Mathios Stone is produced in Europe under strict quality and compliance standards, and is suitable for use in projects that follow EN standards and international best practices. Technical documentation and certifications are available upon request for professional use and permitting.
6. MAINTENANCE & REPAIRS
Mathios Stone requires minimal maintenance. For most applications, occasional cleaning with water is sufficient. Avoid using acidic or abrasive cleaners. In exterior environments, natural rain and airflow often keep the stone clean without intervention.
In most applications, sealing is not required, as Mathios Stone is naturally durable and water-resistant. However, in areas with high water exposure, salinity, or repeated contact with moisture (such as coastal zones, pool areas, or bathrooms), we recommend using a protective sealer to preserve the surface.
For these conditions, we offer Mat Protect Sealer by Mathios — a breathable, water-based solution that helps reduce staining, salt de
Yes. Mathios Stone is made from non-organic, mineral-based materials that do not support the growth of mold, mildew, or allergens. Its breathable structure allows moisture to evaporate, rather than becoming trapped behind the wall — a key factor in long-term indoor and outdoor health.
In addition, Mathios Stone carries a VOC A+ rating, meaning it emits no harmful volatile organic compounds. This ensures clean air quality in indoor environments and makes it a safe choice for homes, schools, and healthcare spaces.
Individual pieces can be replaced easily without disturbing the rest of the wall. Because Mathios Stone is a modular system, repairs are localized. In many cases, the exact model and color can be reordered — even years later — thanks to our controlled, repeatable production system.
Efflorescence — the appearance of white salt deposits on the surface — can occasionally occur if moisture travels through the substrate, carrying salts to the surface. It is not a defect of the stone itself. It can usually be removed with a mild vinegar solution or efflorescence cleaner, and proper installation with correct moisture barriers will minimize the risk.
7. ARCHITECTURAL & DESIGN INTEGRATION
Stone is not just a surface — it’s a statement of permanence, tactility, and material memory. Mathios Stone allows architects to bring those qualities into both modern and traditional contexts, offering depth, shadow, and textural contrast that add richness to façades, volumes, and transitional spaces. It reinforces architectural rhythm while anchoring a project in material authenticity.
Yes — this is one of Mathios Stone’s greatest strengths. With its wide range of regionally inspired textures, mineral tones, and laying styles, it allows architects to create buildings that blend into the landscape, reflect local heritage, or express cultural narratives through material.
Whether it’s a Cretan villa merging into rocky terrain, a restaurant inspired by traditional Iraqi brickwork, or a geometric contemporary home softened by Mediterranean stone, Mathios Stone gives you the tools to root architecture in culture, memory, and place — without aesthetic or technical compromise.
Absolutely. While inspired by traditional stonework, Mathios Stone is widely used in clean-lined, modern designs. Its narrow joints, monochrome palettes, and precise installation make it a natural fit for minimalist or Scandinavian-style façades, urban lofts, and sustainable homes. Many architects use it to introduce warmth, contrast, and narrative into modern structures.
Yes. Mathios Stone includes profiles that are specifically designed to replicate regional stone types, weathered finishes, and traditional laying patterns — making it ideal for historic renovations, rural homes, and preservation-sensitive projects. Its controlled production also ensures consistency, which is critical when matching or extending existing stonework.
Mathios Stone is intentionally three-dimensional — with broken edges, varied relief, and rough surfaces that catch natural light and shadow. This creates depth and richness throughout the day as conditions change. Unlike flat cladding, it gives a wall a sense of mass, story, and age, whether installed flush or in recessed fields and vertical bands.
Yes. Its lightweight and modular format allows it to be used on freestanding structures, fireplaces, double-height interiors, and even curved walls — all without the need for structural stone foundations. With proper substrate and adhesive, it can wrap complex geometries while maintaining visual continuity.
Yes. Mathios Stone is fully compatible with external thermal insulation systems (ETICS). Its low weight and breathable profile make it ideal for use on passive houses, high-performance façades, and sustainable construction. It does not interfere with the insulation layer and adds thermal inertia to the building envelope.
Absolutely. Architects often collaborate with Mathios to create custom wall concepts — mixing textures, tones, and laying styles to develop a distinctive material language. With over 250 color/texture combinations, Mathios Stone can be tailored to fit the unique narrative of any project.
Because it delivers on all fronts: aesthetic richness, material honesty, systemic flexibility, and long-term performance.
