Single Leaf Smoke Vents

Single Leaf

  • The most popular smoke vent mechanism
  • Wide range of sizes
  • Available in Polycarbonate, Glass or Solid insulated lid
  • Centrally mounted, offset or concealed motors

The Single Leaf Smoke Vent type of mechanism is by far the most popular we supply. One of the main reasons is the shear flexibility of its materials and the various ways a Single Leaf Smoke Vent can be opened. A standard single leaf unit is most commonly used for the clearance of smoke in protected areas, such as stairways and corridors.

No matter where abouts in the building your smoke ventilation system is required, we are able to offer fully CE compliant smoke vent products to meet EN 12101-2 regulations.

The Single Leaf Smoke Vent can be supplied with a centrally mounted motor, which can also be off-set to the side should access be required for occasional maintenance. For those looking for a more sleek, minimalist solution, we are able to supply Single Leaf Smoke Vents with completely concealed motors. This means that when the unit is in the closed position with polycarbonate or glass glazing elements, it provides a completely unobstructed view of the sky above.
We are one of the UK’s largest suppliers of smoke vent brands, with roof smoke vents, smoke vent windows and numerous other ventilators in our product portfolio, we are sure we will be able to meet any requirements you have. 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.
