Double Leaf/Industrial Smoke Vents

Double Leaf

  • Suitable solution for controlling smoke over large areas
  • Standard sizes available up to 3m x 3m
  • Available in Polycarbonate, Glass or Solid insulated lid
  • Available CE marked and fully certified to BS EN12101-2

Typically used across large roof areas on industrial or commercial properties helping to disperse smoke above areas such as factories, warehouses and workshops. Double leaf smoke vents clear vast quantities of smoke quickly with integral 24v actuators. Each AOV leaf smoke vent opens to approximately 90 degrees in less than 60 seconds to efficiently and rapidly vent smoke from the building below. Various multi wall polycarbonate glazing options are available with clear, opal, diffused finish or solid insulated lids.

No matter where in the building your smoke vent is required, we are able to offer fully CE compliant smoke vent products to meet and exceed EN 12101-2 regulations along with other safety features such as fall arrest grids to prevent falls from height when the units are in the open position. For noisy environments units can be manufactured with a sound reduction option with acoustic insulation to 44dB Rw.

We are one of the UK’s largest suppliers of smoke vent brands, and are sure to provide you with a solution to suit any requirement. Please feel free to give our technical sales team a call to discuss your purchase with them, or see our brands below for more specific information on the types of smoke vent we offer.
