Type/Mechanism

Single Leaf

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 about in the building your smoke vent 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. This makes your smoke vent an AOV. 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, and are sure to provide you with a solution to suit any requirement.

Single Leaf

Double Leaf

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 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.
