Not all EPS Cement Sandwich Wall Panel products on the market meet official fire safety standards, and it is critical for builders to understand the key testing indicators before making a purchase. A fully compliant grade A non combustible EPS Cement Sandwich Wall Panel must pass the ISO 1182 fire test, showing no flame spread, no temperature rise above the testing limit and no burning drips during the full 30 minute test. The fire resistance limit of a 120mm thick qualified EPS Cement Sandwich Wall Panel must reach at least 3 hours, which means it can block fire and high temperature from passing through the wall for a long time during a building fire. You should always ask the supplier for the official third party fire testing report of the EPS Cement Sandwich Wall Panel, instead of trusting unsubstantiated verbal claims about fire performance. Using a non certified low fire rating EPS Cement Sandwich Wall Panel will not only fail local building inspections, but also create huge hidden safety risks for the entire building.
