Engineered for a Flawless & Efficient Insta

Our Stone Cladding panel system is engineered from the ground up for the most demanding commercial and high-end residential projects. Discover the features that ensure a safe, durable, and lasting architectural facade.

Robust Cement Backing System

The core of this system’s strength is its solid, cement-reinforced back. This creates a uniform surface for a powerful, monolithic bond with installation mortars and provides exceptional panel rigidity, preventing flex and offering a superior defense against impacts in high-traffic areas.

High-Density Architectural Stone

We select only our most durable and non-porous materials for this collection, primarily high-density Granite, Slate, and Quartzite. These stones have extremely low water absorption rates, making them the proven choice for long-term performance in harsh, freeze-thaw, and coastal climates.

Precision Sizing & Calibration

Each panel is calibrated to a tight thickness tolerance. This manufacturing precision is critical for architectural applications, ensuring a flat, uniform final surface across large facades and simplifying the installation process for contractors, especially in systems that require perfect alignment.

Factory-Made Full-Depth Corners

We provide a complete system. Our factory-made, two-piece L-shaped corner units are also cement-backed and engineered to the same robust standard as the flat panels. This ensures the most vulnerable part of the wall has the same strength and durability as the rest of the facade.

Rainscreen System Compatibility

Our Stone Cladding panels are ideal for use as the outer leaf in a modern rainscreen facade system. When installed on a channel or furring system, they protect the building’s waterproof membrane while allowing for ventilation and moisture drainage, contributing to superior building performance.

Non-Combustible for Life Safety

Safety is paramount in commercial and multi-family construction. Composed of 100% natural stone and cement, our cladding system is inherently non-combustible and achieves a Class A Fire Rating (ASTM E84), making it a safe and responsible choice for projects with the strictest building code requirements.

The Installation Process Overview

A highly visual, 5-step process overview. Each step has an icon, a title, and a one-sentence description.

Step 1: Structural Substrate Preparation

  • For this heavy-duty system, the installation must be on a clean, dry, and structurally sound load-bearing wall, such as a Concrete Masonry Unit (CMU) block or a poured concrete wall. For framed walls, an appropriate cement backer board must be properly installed and rated for the panel’s weight.

Step 2: Waterproofing & Mortar Application

  • A critical step for facade longevity. A code-compliant weather-resistant barrier (WRB) must be properly installed behind the panels. We recommend a high-performance, polymer-modified thin-set mortar (conforming to ANSI A118.15), applied to both the substrate and the back of each panel (‘back-buttering’) for maximum adhesion.

Step 3: Panel & Corner Installation

  • Always start from the bottom on a perfectly level starter track. Panels are set in a running bond pattern to stagger joints. Our robust, two-piece cement-backed corner units are installed as you progress up the wall to ensure a solid, integrated corner structure that matches the strength of the facade.

Step 4: Cutting & Mechanical Fastening

  • Use a high-quality wet saw with a diamond blade for all cuts. For projects on high-rise buildings or in high-wind zones, a supplementary mechanical fastening system (such as stainless steel clips and channels) may be required by local building codes in addition to the mortar bond for ultimate security.

Step 5: Control Joints & Sealing

  • For large facade areas, control and expansion joints must be incorporated into the design to allow for natural building movement. After curing, we recommend applying a high-quality, breathable, impregnating natural stone sealer to protect the facade and make future cleaning easier.

Visual / Cross-Section

Mesh & Adhesive Backing System

Cement Backing System

Core Advantage

Logistical Efficiency & Cost-Effectiveness

Maximum Durability & Performance

Content Detail

The thinner profile and lower weight of this system allow you to load up to 20-25% more square meters into a single container. This significantly reduces the landed cost per unit (product cost + shipping), maximizing your profitability and allowing for more competitive retail pricing.

This system is engineered for ultimate long-term performance. The robust, solid backer provides superior bond strength and weather resistance, making it the definitive choice for projects where durability and peace of mind are non-negotiable.

Bonding Mechanism

Relies on a multi-point adhesion: the bond of the installation mortar to the mesh, and the factory bond of each individual stone to that mesh.

Creates a powerful, monolithic bond. The installation mortar bonds chemically and mechanically across the entire, uniform cementitious surface, becoming an integrated part of the wall.

Structural Rigidity

More flexible. The lighter weight is easier for a single person to handle during interior installation.

Extremely rigid and robust. The solid back prevents flexing and provides superior impact resistance, which is critical for demanding exterior or public-facing projects.

Long-Term Exterior Performance

Good for decorative exterior use in mild, dry climates. In extreme weather, the multiple bond points can be more susceptible to moisture ingress and freeze-thaw stress over many years.

Exceptional. The solid, non-porous backer protects the primary bond from the elements, ensuring maximum longevity and performance in even the most challenging climates.

Best-Suited Applications

  • High-volume interior projects 
  • Residential feature walls & backsplashes 
  • Commercial retail displays
  • Price-sensitive markets or projects 
  • Distributors focused on maximizing inventory per shipment
  • Large-scale commercial facades 
  • All exterior applications in harsh climates (freeze-thaw, high humidity, coastal)
  • High-traffic public areas 
  • Projects where longevity is the highest priority

Feature / Consideration

Top Source Natural Stone Cladding

Architectural Metal Panels (e.g., ACM)

Precast Concrete Panels

Aesthetics & Prestige

✓ Authentic, Timeless, and Unique. Every panel is quarried from the earth, offering natural color depth and texture that cannot be replicated. It conveys a powerful sense of permanence and luxury.

– Modern, Uniform, and Sleek. Offers a clean, industrial aesthetic with a wide range of colors. The surface is uniform, lacking the unique character of natural materials.

– Robust and Utilitarian. Can be formed into various shapes, but often presents a monolithic, industrial look. Texture and color are manufactured and can appear repetitive.

Longevity & Durability

✓ Exceptional (100+ Year Lifespan). Natural stone is one of the most durable building materials known. It is highly resistant to impact, abrasion, and weathering. It does not rot, warp, or degrade from UV exposure.

X Moderate (20-40 Year Lifespan). The panel itself is durable, but the painted or coated finish is susceptible to fading, scratching, and chalking over time. The material is also prone to denting from impacts.

– High (50-70 Year Lifespan). Very durable and weather-resistant, but can be prone to chipping at the edges (spalling) and may require resealing over its lifespan to prevent water ingress.

Fire Performance

✓ Superior (Non-Combustible). As a 100% natural stone and cement system, it is inherently non-combustible and achieves the highest fire safety ratings (e.g., Euroclass A1), making it an ideal choice for high-rise and public buildings.

X Variable (Core Material is Key). Fire performance depends entirely on the panel’s core material. Some cores are flammable (PE), while others are fire-retardant (FR) or non-combustible (A2), which significantly impacts cost and safety.

✓ Excellent (Non-Combustible). Concrete is a non-combustible material, providing excellent fire resistance for building facades.

Maintenance Requirements

✓ Very Low. Requires only occasional cleaning with water to maintain its appearance. It does not need repainting, refinishing, or frequent resealing, offering significant long-term savings.

– Low. The smooth surface is easy to clean. However, scratches or dents can be difficult to repair seamlessly, and faded panels may require costly replacement or recoating.

X Moderate. The surface is porous and typically requires periodic resealing (every 5-10 years) to protect against staining and water damage, especially in freeze-thaw climates.

How We Ensure Quality and Reliability From Our Factory to Your Door

As a direct manufacturer, we have complete control over our process. This transparency is your assurance of quality, consistency, and a secure supply chain for your most critical projects.

Precision Manufacturing & Quality Control

Our process begins with premium raw materials, often sourced from our own quarries, ensuring a consistent geological foundation for every panel. We use advanced, computer-guided infrared cutting equipment to achieve precise dimensions with minimal tolerances. This precision is critical for ensuring our cement-backed panels fit perfectly within architectural facade systems. After cutting, experienced artisans assemble each panel by hand. Throughout production, our dedicated QC team performs inspections at three separate stages—post-cutting, post-assembly, and pre-packaging—to guarantee every single piece meets our high standards for structural integrity and aesthetic consistency.

Advanced & Efficient Processes

We use advanced infrared cutting equipment to ensure every panel is precisely cut to the imperial dimensions (e.g., 6" x 24") that the North American market expects. This accuracy leads to a perfect fit, which reduces on-site installation time and costs for contractors.

Secure & Professional Packaging

We understand that protecting your investment during transit is critical, especially for heavy-duty architectural products. Our multi-step packaging process is designed for the rigors of international shipping. Panels are first separated by protective layering and then tightly packed into sturdy, reinforced cardboard boxes. These boxes are then stacked securely into robust, fumigated, and heat-treated (ISPM 15 compliant) wooden crates that are built to withstand heavy loads and prevent any movement.

Reliable Global Loading & Shipping

A well-packed crate is only half the battle. Our experienced logistics team ensures that every container is loaded strategically to maximize space and, more importantly, to eliminate the risk of shifting during transit. We use heavy-duty steel straps to secure the crates to the container walls and floor, and utilize industrial-grade airbags to fill any gaps. This meticulous process is why we can confidently ship over 220 containers annually to partners worldwide, ensuring your order arrives intact and on schedule.

Your Questions on Stone Cladding Panels, Answered

An expanded 8-question accordion-style FAQ.

Due to their weight (approx. 13-16 lbs/sqft or 65-78 kg/m²), these panels must be installed on a structurally sound, load-bearing wall like a concrete masonry unit (CMU) or an appropriately engineered steel-stud frame. We provide full product data for your structural engineer’s review.

Yes, they are frequently specified for mid-rise and high-rise projects. Applications above a certain height (check local codes) will typically require a mechanical fastening system (e.g., clips and channels) in addition to adhesive to manage wind load and ensure safety.

The system, composed of natural stone and a cementitious backer, is non-combustible. It achieves a Euroclass A1 or an ASTM E84 Class A fire rating, making it one of the safest choices for building exteriors.

Our panels are an excellent choice for a rainscreen facade. When installed on a channel system, they create a durable outer screen that protects the building’s waterproof membrane from UV and impact, while the air cavity behind allows for effective moisture drainage and ventilation.

The solid cement back creates an impermeable layer that protects the bond from water ingress. This is critical in preventing failures caused by freeze-thaw cycles in cold climates. It also provides a stable, rigid base that resists warping or degradation in extreme heat.

For large installations, control and expansion joints must be incorporated into the facade design per standard architectural practice. These joints are typically filled with a flexible sealant and allow the facade to safely accommodate thermal expansion and minor structural movement.

Natural stone is one of the most durable building materials on earth. When installed correctly as part of a proper wall assembly, the lifespan of the stone itself can be measured in centuries. The system is designed to last the lifetime of the building with minimal maintenance.

Yes. We understand that commercial projects have unique challenges. Our technical team is available to work with architects and engineers to provide project-specific data, installation details, and consultation to ensure our products are specified and installed correctly.
