Building Smoke Ventilation Systems

Nobody wants to think about the possibility of fire, but it’s a risk in any building, however the risks of death from smoke inhalation can be significantly reduced if the correct smoke ventilation system is installed.

The smoke vent selector below will help you find the right smoke vent for your application.

Fire burns, Smoke kills!

Most fire deaths are caused by smoke inhalation. Even a small fire can quickly fill a building with smoke, causing disorientation and preventing occupants from seeing accessible escape routes. Smoke inhalation can rapidly overcome and incapacitate. And with homes and commercial buildings featuring synthetic and dangerous materials, smoke is combined with toxic gases.

Take automatic action

Smoke ventilation systems with automatically operated roof ventilators (AOV smoke ventilators) significantly improve safety in the event of a fire. Triggered by the fire alarm system, the AOV smoke control systems open to a predetermined angle to allow smoke and heat to disperse from the property. This creates a smoke-free layer, improves visibility in escape routes and increases occupants’ escape time, whilst also assisting fire rescue access.

Make an informed decision

Fitting the right, fully-certified smoke vent is critical for safety. As long-standing experts in AOV smoke ventilators, NDC will advise on the correct smoke vent for your project and provide a solution that is CE marked against BS EN 12101 – 2 to ensure compliance with building regulations.

Smoke Vents by Type/Mechanism

No matter what you require, we are sure to have a smoke mechanism type to suit your needs. Depending on the building plan or Schematic you may require a smoke vent with a particular mechanism. This could be dictated by the amount of free flow area of smoke that is required to be evacuated from the building or the location of the smoke vent within either the roof space or wall area available.
Some mechanism types, like the single leaf, are perfect for small area ventilation or areas where the smoke vent may be used for occasional access to the roof for maintenance. Others, like the double-leaf smoke vent are perfect for large areas where a more industrial specification may be required. Louvre smoke ventilators are great for use in locations that may be exposed to high wind loads, particularly in high rise buildings, coastal locations or areas that require a higher security specification.
If you require any help or advice please feel free to call our sales team who will be happy to help.
