The result is a breathable, high-performance material offering superior thermal and acoustic comfort. Ideal for walls, roofs, and façades, STEICO boards regulate moisture, enhance energy efficiency, and remain stable over time with little maintenance. Compatible with natural plasters and vapor-permeable finishes, they’re both functional and eco-friendly.
