Fire safety is always the top priority for any construction material, and it is especially important for panel products that use foam insulation cores, so it is critical to get accurate, test backed information about the real world fire performance of EPS Cement Sandwich Panel before you select it for your project. Many people have outdated assumptions about EPS foam being highly flammable, but modern EPS Cement Sandwich Panel produced according to current industry standards goes through strict fire treatment processes that make it fully compliant with most national building fire codes.
The two outer layers of the EPS Cement Sandwich Panel are made of non combustible reinforced cement, which will not catch fire, burn or release toxic smoke even when exposed to direct high temperature flame. This means that the EPS foam core inside the panel is completely sealed and protected from open flame on both sides. When the panel is exposed to a building fire, the cement skins maintain their structural integrity for more than 2 hours in standard fire resistance tests, preventing fire and hot gas from spreading through the wall to adjacent rooms. High quality manufacturers also add flame retardant additives to the EPS core during production, so even if the core is exposed to extreme high temperature, it will melt slowly instead of sustaining active flame spread.
It is important to match the correct fire rated EPS Cement Sandwich Panel to your specific project type. For low rise residential buildings, the standard grade panel meets all local fire code requirements for exterior and interior partition walls. For commercial buildings, warehouses and public spaces, you can select the upgraded fire retardant grade EPS Cement Sandwich Panel that passes the 3 hour fire resistance test, which is accepted by most building safety departments for public occupancy spaces. You should always request the official third party fire test report from your supplier before purchase, to confirm that the product you are ordering meets the exact fire safety requirements specified in your local building permit documents.
