Smoke curtain |
摘要 |
A heat resistant curtain has a vent typically extending up from a bottom edge. At the vent, flaps of the curtain on either side of the vent have marginal overlaps. To these are stitched elevated temperature resistant hook and loop fastening tapes. These normally keep the vent closed. The curtain is provided with a bottom bar drawn up to close the head box when the curtain is not deployed. When the curtain is deployed, the bottom bar rests on the floor.
