Smoke Curtains

The fabric used for 1 hour fire rated curtains is generally used for smoke curtains.
They can be either static or automatically controlled.
The smoke curtains may not be installed with side guides as there is a tolerance allowed around the edges through which smoke may seep.
The overlapping of one motorised curtain against another is used to cover larger expanses.
The curtain is retained together with the overlapping and also that of a steel rod fed through the bottom pocket.
