What do you Know About the Fire Behavior of an EPS Sandwich Panel?
An EPS Sandwich Panel shows resistance and insulation for water, heat, sound waves, and air. This insulation is due to the expanded polystyrene material.
EPS is renowned for its B1 level fire retardation. So it can be said that the panel is less combustible. It has resistive fire behavior.
At the burning point, polystyrene can be ignited like other organic materials but it happens if the temperature may rise above 300°C with long retention of flame.
But an EPS Sandwich Panel can be made more insulated by using different insulating sheets. On basis of fire behavior, EPS Sandwich Panel is classified as ‘fire retardant’. EPS core of the panel categorizes it in E60 / EW 60 fire resistance class.
How an EPS Sandwich Panel is Insulated?
The best heating and acoustic insulation are the main features of an EPS Sandwich Panel and it is made insulated in the following way:
