What Are the Different Types of Smoke Control Systems?

Smoke control systems help keep occupants safe and provide a safe evacuation during a fire.

These systems require many people to be involved during the design, installation, and testing process. Working with experienced professionals from the beginning of a project is important.


A mechanical smoke control system uses fans to create pressure differentials across barriers to keep smoke out of or in a specific area. This type of smoke control is commonly used for staircase and elevator shafts but can also be used in other spaces within the building to protect against the spread of fire.

There are a few different types of mechanical smoke control systems. These include airflow, pressurization, dilution, and cross-ventilation.

When designing a smoke control system, you need to consider the size of the building and how big a fire will be. It will help you determine how much smoke you need to cover the area and how big the smoke control equipment should be. Check smoke control systems by sgspecialties.com to pick the right one for you.

After you have the smoke control system designed, you will need to test it. It is why it is so important to get the right person involved in every project stage. A proper fire protection engineer will understand the different types of smoke control systems and the codes that govern them.

With a professional fire protection engineer in charge of the process, you can rest assured that all the work is done right and that the building will be safe for the people who use it. The key is to get the details right, which means you need to start planning for smoke control in the early stages of a project.

Natural smoke control systems manipulate the innate characteristics of smoke to remove it from the building, keeping escape corridors and stairs clear for firefighting personnel and occupants. These systems are mainly used in residential buildings and are available in various options to suit your property requirements.

Unlike powered smoke ventilation, these systems do not rely on motorized fans to achieve their function and are, therefore, more cost-effective over the longer term. The system uses the innate properties of hot air and thermal buoyancy to remove smoke from the building, using apertures in strategic locations to enable it to leave.

This process, in turn, allows fresh air to enter the building and cool it down as it travels through the system. It allows the occupants of the building to move to another safe area and avoid the risk of heatstroke.

The systems are often automated to activate when a fire is detected and can even be fitted with an intelligent energy management system that measures carbon dioxide levels in the building and integrates into existing building automation systems. These devices can also be connected to a backup battery facility, which still works even when the main power supply fails.

They are also a very efficient method of removing smoke from a building and can be an ideal solution for multi-occupancy buildings where maintenance budgets are limited. These systems are also very resilient and withstand daily use and vandalism.

Cross Ventilation

Cross ventilation is a system that provides natural air movement within buildings. It uses the wind to move air and can be used in residential and commercial buildings. It is an effective alternative to mechanical ventilation systems and less expensive.

It can also help reduce the amount of moisture that accumulates in a building, a common cause of mold and other health problems. It is particularly important in older homes with a high likelihood of mold developing inside walls and ceilings.

Combining automated and natural cross-ventilation systems is the best way to achieve maximum air movement in your building. Automated ventilation will keep your windows open as much as possible, while natural ventilation will ensure that the air is circulating continuously throughout the room.

However, it is important to note that having both is not always possible. For instance, if you live in a very old house with many wooden walls, it may not be possible to have both types of ventilation.

It is why it’s so important to plan your home carefully and ensure that you have enough openings on both sides of the house. The positions of these openings will affect the direction that the wind will blow through your home. It is especially important when it comes to cross ventilation, as you want the breeze to come from the windward side of your home and go around areas where people are likely to be.

The openings you choose will also influence how your home is shaped. For example, a curved roof will affect how the wind blows through your home. You can use this information to help you decide which vents, windows, and doors are most suitable for your home.

As with all building design projects, you should be aware of any obstructions that might interfere with airflow through your home. It can include things like walls and partitions, and furniture that might be blocking the airflow.

Another important thing to remember is that you should never place your windows directly above each other. It will prevent the breeze from flowing through them effectively.
