Stone composite – the foundation of durability

All Steni panels are made with a proprietary stone composite core – a material that combines extreme impact resistance with flexibility and low environmental impact. This enables factory-precise panels with custom dimensions, curved shapes, and long-term structural integrity. Our stone composite is the reason we can deliver façade panels that perform beautifully for more than 100 years.

The benefits of natural stone and stone composite façades

1. Exceptional durability and low maintenance

Steni’s façade panels are made to resist moisture, frost, UV radiation and wear – even under the most demanding weather conditions. Thanks to the robust stone composite core, they do not absorb water, crack or delaminate – and require minimal upkeep over time.

2. Authentic appearance with natural variation

Panels with natural stone surfaces offer a visually rich and tactile expression. Each panel captures the nuance of real crushed stone or recycled glass, giving depth and texture that enhances any building.

3. Design freedom and format flexibility

With flexible sizing, large panel formats and the ability to create curved elements, Steni’s stone composite panels open up unique design possibilities. Choose from smooth or coarse surfaces – and combine with over 80 colours for a tailored architectural expression.

4. Built for circular construction

Our natural stone and stone composite panels are developed with circularity in mind. Steni Nature is available with recycled content, and all Steni panels are 100% recyclable, backed by EPDs and low-carbon lifecycle data. They support green building standards like BREEAM and ISO 14025.

5. Proven long-term economy

Stone composite provides consistent performance over decades. With virtually no maintenance costs and outstanding resistance to damage, these panels offer one of the lowest life-cycle costs in the façade industry – and a sharp look that lasts.

Natural stone meets future-proof design

Steni Nature is our sustainable façade panel made with a surface of crushed natural stone, olivine, or recycled glass. With a 60-year functional warranty, it offers timeless aesthetics and long-term performance – engineered for architecture and tough Nordic climates. It’s a durable, low-maintenance solution with a premium look that lasts.

The same stone composite technology is used in Terra by Steni – our façade system for plinths and foundations. These panels improve drainage, insulate better than traditional solutions, and prevent moisture-related damage. The result: dry basements, elegant finishes and long-term savings.
