We were asked to work with the architect to manufacture and install some fire and smoke curtains that would seal off a stairwell in the event of a fire.
The fire curtains had to be concealed within a box section at high level so they were not visible when not in use. They also needed suitable access for maintenance. The guide rails at the sides of the fire curtains had to be hidden within curved vertical columns again so that they were not visible when not in use.
