EPS sandwich panels
EPS sandwich panels have a polystyrene foam core between two colour-coated steel sheets. They are the lightest and lowest-cost panel, used for warehouses, site offices, temporary buildings and dry internal partitions where fire rules allow a combustible core.

Questions
Is EPS panel fireproof?
No. EPS is a combustible core. Where your code requires a fire rating, choose rock wool, PU edge-sealed rock wool or silica rock.
