Sto Corp. Expands Fiber Cement Color Palette

ATLANTA -- Sto Corp., a developer of wall cladding systems, air barriers, coatings, and restoration systems, is expanding its Fiber Cement Rainscreen System color palette with the addition of the Mezzo collection.

The expanded offering now includes three curated color collections and 17 total color options, giving architects and designers greater flexibility when creating distinctive façade designs.

StoVentec Fiber Cement is a complete ventilated rainscreen cladding system engineered by Sto to integrate seamlessly with all exterior wall components, providing enhanced performance, durability, and design versatility.

The three new Mezzo colors introduce subtle tonal variations inspired by natural materials. Ranging from light brown to dark gray, the additions complement contemporary architectural palettes while maintaining the balanced, organic character that defines the Mezzo collection.

The panels feature through-body pigmentation, ensuring consistent color throughout the panel for improved durability and long-lasting aesthetics.

With the expanded palette, StoVentec Fiber Cement now offers three distinctive color collections:
•     Primara Line: A grey-bodied panel with an opaque surface finish and a smooth texture with a lightly sanded grain.

•     Mezzo Line: A refined collection blending organic texture with modern simplicity, featuring balanced tones and smooth finishes.

•     Strata Line: Panels with pigmented bodies and ultra-smooth finishes that create a sleek, contemporary aesthetic.

Beyond aesthetics, StoVentec Fiber Cement is designed to deliver high-performance building envelope protection. The rainscreen system integrates noncombustible continuous insulation, a robust air and water-resistive barrier, engineered sub-construction, and high-density fiber cement panels, providing durability and long-term weather resistance.

To accommodate diverse design preferences, the panels are available with both concealed and visible fastening options, allowing architects to achieve either clean, uninterrupted panel surfaces or a more expressive façade aesthetic.

“StoVentec Fiber Cement continues to evolve to meet the design and performance expectations of today’s architects,” said Karine Galla, Director of Product Management. “The expanded color collections, combined with flexible fastening options and proven durability, provide architects with a rainscreen solution that delivers both creative freedom and reliable performance.”

Panels are available in standard sizes up to 4’ x 10’ and thicknesses of 8–10 mm and can be installed horizontally or vertically in stacked or staggered layouts to create custom patterns and façade expressions.
