Silver Group - Your proven smoke ventilation experts
Ventilation Systems and AOVs
These smoke ventilation systems open mechanically when triggered by stimuli from heat or smoke detectors – their primary function being to allow for natural ventilation of air and smoke as part of an optimised fire safety system. Silver Group working in partnership with SE Controls, the UK’s leading manufacturer of smoke ventilation controls, are able to design, install and provide ongoing maintenance for all types of smoke ventilation and heat exhaust systems for buildings. These innovative systems have ranged from commercial to multi-occupancy residential as well as local authority projects.
Although best suited to new projects – which allow you to integrate an AOV into the structure of complex buildings as a comprehensive, natural ventilation system – AOVs can also be fitted to existing projects as part of an integrated fire safety or smoke control solution. In a fire, smoke is considered a bigger threat than fire itself. That’s why fire safety often implores us to crawl along the floor below smoke. One of the other biggest threats during a fire is firefighters being unable to access buildings safely and quickly due to any structural damage caused. As AOVs open automatically and are built into the most structurally sound parts of the building (the outer walls or roof), AOVs allow smoke to rise above escape routes, giving significantly improved visibility and ventilation to occupants, as well as giving firefighters quick and easy access to a building in order to carry out fire and rescue operations. This means earlier firefighting, better safety, and less permanent damage to your facilities or offices.
This European standard requires that natural smoke and heat exhaust ventilators installed as a components of a natural smoke and heat exhaust system are CE marked and meet the Construction Products Regulations. For the products to meet this approval, they must have passed many rigorous tests. Regardless of the repeated tests in extreme hot and cold temperatures, with snow and high winds as additional factors, the vents must suffer no more than a 10% loss in aperture of opening. They operate with 60 seconds on activation.
