Fire safety is non-negotiable for any construction material, especially for public spaces, schools and industrial facilities — and the EPS Cement Sandwich Wall Panel has passed strict global fire resistance tests to earn top safety ratings. Many people mistakenly assume that any product with EPS foam will be highly flammable, but the EPS core inside a standard EPS Cement Sandwich Wall Panel is treated with advanced flame-retardant additives that stop it from sustaining combustion on its own. The two outer cement layers are completely non-combustible, creating a protective barrier that prevents fire from spreading through the wall for up to 4 hours, depending on panel thickness.

Independent third-party lab tests have confirmed that the 120mm thick version of EPS Cement Sandwich Wall Panel meets the A1 fire rating, the highest possible class for non-combustible building materials. This makes it fully approved for use in high-risk areas like hospital corridors, school classrooms and shopping mall partition walls. Unlike some lightweight wall panels that release toxic smoke when exposed to high heat, the cement surface of the EPS Cement Sandwich Wall Panel produces almost no harmful fumes during a fire, giving occupants more time to evacuate safely and reducing damage to building interiors.
