Automatic fire curtain which seals off an area to contain the movement of flames with a defined fire resistance time.

Such curtains can also be partially deployed in the event of a fire to control the movement of gases from a fire within buildings before they are fully used for fire protection. It has been designed and tested according to BS 8524-1:2013, and achieves E180 and EW20 classifications.

It unrolls in a gravity fail safe manner without needing power (gravity fail safe). The fire curtain consists essentially of a roller in a galvanized steel housing, the roller comprises a flexible heat resistant fabric which is impervious to smoke and hot gases, wound around a tube. A heavy bottom bar fitted to the bottom edge of the fabric ensures that the curtain deploys as designed.
