Bolton Gates rolling smoke curtains are designed to restrict the lateral spread of smoke and hot gases along the underside of a roof, ceiling or balcony within a building in the event of fire. They are used as part of a smoke control system to create smoke reservoirs from which smoke and hot gases can be extracted or to stop the spread of smoke allowing valuable time for occupants to escape. Bolton Gate’s smoke curtains have been successfully tested and meet the requirements of BS 7346 Part 3, BS 476 Part 20 and BS EN 12101-1 and are supplied with a gravity fail safe system ensuring closure in the event of power failure. They are available in wide spans and can be face fixed, soffit fixed or suspended on rods. Smoke curtains can be supplied in unlimited widths by use of our overlap system with curtains up to 5 metres wide being serviced by single span rollers.
