The ARDOGRES® GRIGIO PIETRA 40X40 (16"X16") porcelain stoneware roof tile is one of the most iconic and versatile solutions within the Ardogres collection, designed to reinterpret the timeless character of traditional mineral roofing through contemporary technology and performance.
Installed in the classic diamond-shaped “French pattern”, GRIGIO PIETRA 40x40 faithfully recreates the appearance of natural stone roofing traditionally found across Alpine and Northern European architecture. Its structured surface and natural grey shades provide an authentic and elegant aesthetic suitable for both heritage renovations and modern architectural projects.
Widely used in Norway and increasingly appreciated in international markets, this tile has become a highly effective alternative to traditional stone roofing systems as well as old asbestos diamond-shaped coverings, offering the same visual character with the superior durability and reliability of porcelain stoneware.
GRIGIO PIETRA 40x40 is equally suited for contemporary roofs and ventilated façades, making it ideal for modern residential architecture, mountain chalets, hospitality projects and high-end building envelopes.
Thanks to the technical properties of porcelain stoneware, the tile guarantees excellent resistance to frost, thermal shock, UV exposure, hail, abrasion and harsh weather conditions, with extremely low water absorption and minimal maintenance requirements. Its expected lifespan exceeds 100 years.
The lightweight roofing system — approximately 25 kg/sqm — combined with the mechanical fixing system using screws and slotted holes, ensures outstanding stability, ease of installation and long-term reliability, even in demanding climatic environments.
Like all Ardogres solutions, GRIGIO PIETRA 40x40 is fully recyclable and reusable, combining architectural authenticity, sustainability and advanced Made in Italy technology.
