GLASROC® X CONFIRMED AS WEATHER-RESILIENT AFTER 12 MONTHS EXPOSURE

Saint‑Gobain announces the validation of Glasroc^® X performance following a comprehensive assessment program, combining accelerated ageing tests monitored by CSTB (Centre Scientifique et Technique du Bâtiment) with real‑life exposure tests conducted across multiple locations worldwide. These tests subjected the product to a wide range of climatic conditions, including heavy rainfall, extreme heat, snow, and strong winds. Performance measurements carried out before and after exposure confirm that Glasroc^® X fully preserves its properties over time.

Following a 12‑month evaluation under highly varied and demanding climatic conditions - including heavy rainfall, extreme heat, snow, and strong winds - the CSTB confirmed that the performance of Glasroc^® X remains unchanged. This independent assessment reinforces the product’s robustness and reliability in real‑life construction environments.

Glasroc^® X was specifically engineered to deliver high durability and stability when exposed to the elements. The tests that were done provide additional assurance to contractors, façade specialists, and building owners: even in the event of project delays or prolonged construction phases, installations incorporating Glasroc^® X can proceed with confidence. The boards maintain their integrity over time, ensuring that the façade’s external layer remains unaffected by harsh weather.

Glasroc^® X is widely used across the world for lightweight façade systems and exterior ceiling applications. Its reinforced gypsum core and glass mat technology offer excellent dimensional stability, mold resistance, and long‑term durability, making it a preferred solution for demanding projects.

With these tests, Saint‑Gobain strengthens its commitment to delivering high‑performance solutions that support efficient, resilient, and sustainable construction practices.
