This work analyzed the behavior of a sealing system with expanded polystyrene (EPS) core, in terms of fire resistance criteria and the behavior of the EPS core in relation off ire reaction. The analysis was made by laboratory tests following the Brazilian standards NBR 5628:2001 e NBR 16965:2021. system presented failure of its bearing capacity, at 17 minutes, due to the conjunct action of thermal bow phenomenon and the loading. For this, by standard criteria, its integrity and thermal insulation loss was declared. Regarding the fire reaction tests, it was observed that the EPS degraded when the temperature of 210 °C was reached, but it did not present continuous flames or excessive smoke.
