Smoke extraction is one of the essential means to promptly secure a building when there is a fire.

Allowing the smoke and toxic fumes to evacuate undoubtedly contributes to the paramount safety of the people still inside of the building. It's a well-known fact that smoke inhalation is actually the most frequent cause of injury or death in the case of a fire. The smoke and fumes can lead to unconsciousness after only three breaths.​​

Automated windows is a very efficient smoke and heat extraction system that can be installed to draw out toxic smoke. Windows can be automated by the installation of actuators that react to sensors to open or close depending on the settings. These windows could be opened to allow for natural air flow, or they can open in case of an emergency to extract smoke from a building.

This is a very cost-effective, low capital method of delivering a smoke ventilation system. As well as the advantages of allowing natural daylight in the building and then doubling as a natural ventilation system.

These windows can be controlled either by fully automated systems or with the help of a remote control. However, in the event of a fire emergency, the windows will open automatically upon the detection of any smoke.

Automated windows can also be fitted with the secondary functions of having rain sensors or thermostats that operate depending on the temperature and weather. Open, and closing of the automated windows can also be based on a timer.

Because of the fact that the buoyancy of hot smoke causes smoke to rise, automated windows are installed high-up and out of reach. These smoke and heat extraction systems rely on smoke being extracted from above a supply of fresh air below.
