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:

• The panel is featured with an energy-efficient EPS core. EPS consists of polystyrene beads that are highly inert to react with any molecule. So EPS core makes the panel more resistant and insulated.

• Secondly, the panel steel facings are corrosion-resistive. Steel plates are pre-painted with PPGI or Galvalume for making the panel more insulated.

• Additionally, put some thermal barriers for increasing the thermal insulation of the panel.

Why is an EPS Sandwich Panel Renowned for its Inert Capacity?

EPS Sandwich Panel is highly durable and reliable in its performance due to its inert capacity.

The panel consists of steel plates and an EPS core. The extended polystyrene core is made of chemically inactive polystyrene beads. For its inertness chemistry, the core part of the panel acts as the best insulating material.

The  ‘λ’ value of the panel also depends upon the core region material.

The thermal conductivity of an EPS Sandwich Panel is λ = 0.040 W/m*K. It is in reflection of the thermal insulation/resistance of the panel.

The coefficient of thermal conductivity for EPS is very low which shows that EPS is a good insulating material and heat resistant. So it is more preferred for applications requiring insulating properties.

What is the Acoustic Resistance of an EPS Sandwich Panel?

Acoustic Resistance

An impedance of sound waves conduction by a specific insulating material is called acoustic resistance.

EPS Sandwich Panel has also distinctive acoustic resistance. The measure of the acoustic resistivity for a specific material is measured by the coefficient of acoustic resistance represented by ‘Rw ’.

The acoustic resistance of the panel is Rw= 23-24dB. It can decouple the sound waves configuring noise reduction in buildings or structures requiring sound insulation.
