Fire Protection Solutions for Ductwork and Ventilation Systems

In buildings and industrial structures, ductwork and ventilation systems play an important role in ensuring air quality and occupant safety. However, in the event of a fire, these systems can become channels for the spread of fire and smoke, posing a great danger. Therefore, the application of fire protection solutions, especially fireproof air duct cover, is extremely necessary to prevent the spread of fire and smoke through different areas of the building.

What is fireproof air duct cover?

Fireproof duct lining is a protective solution used to cover the outside of ducts and ventilation systems in buildings. The main purpose of fireproof lining is to prevent the spread of fire and smoke through these ducts in the event of a fire.

Working principle

Fireproof duct lining is usually made from high-temperature resistant insulating materials, capable of withstanding temperatures up to thousands of degrees Celsius for a long time. When a fire occurs, this lining will create a protective barrier, preventing fire and smoke from entering the duct and from there spreading to other areas in the building.

Popular types of fireproof lining materials

• Glass wool: Made from glass fibers, has high heat resistance and good insulation.
• Rock wool: Made from rock fibers, has very good fire resistance and sound insulation.
• Insulation panels, fireproof panels: Combined from many different layers of materials to enhance heat resistance and fire resistance.

Why is it necessary to cover air ducts with fireproofing?

Prevent the spread of fire and smoke

The duct and ventilation system not only provides air but can also become a path for fire and smoke to spread to different areas of the building when a fire occurs. Covering air ducts with fireproofing will help prevent this spread, ensuring safety for the entire building.

Protecting life and property

Fireproofing ductwork helps protect human life and minimize property damage by keeping fires from spreading too quickly, creating valuable time for rescue and extinguishing fires.

Complying with safety standards

Many countries and regions have set fire safety standards that require fireproofing solutions for ductwork and ventilation systems. Fireproofing ductwork not only ensures safety but also meets legal regulations.

Fireproofing solutions for ductwork and ventilation systems

Fireproofing with glass wool

Glass wool is one of the popular materials used for fireproofing ductwork. With high insulation and heat resistance, glass wool can keep ductwork from being affected by high temperatures in the event of a fire.

Advantages:

• Good insulation and fireproofing.
• Light weight, easy to install.

Disadvantages:

• May cause skin irritation when in direct contact.

Fireproof wrapping with mineral wool

Mineral wool, also known as Rockwool, is an insulation material made from stone fibers. This material has high heat resistance and is non-flammable, making it an ideal solution for fireproof wrapping of air ducts.

Advantages:

• Excellent heat resistance and fire resistance.
• Effective sound insulation.

Disadvantages:

• Higher cost than glass wool.

Fireproof air duct cover with insulation panels, fireproof panels

Insulation panels, fireproof panels are applied with Fireshield Pro technology from KH Shield to enhance heat resistance and fire resistance. This type of material is often used in projects requiring high safety levels.

Advantages:

• Excellent heat resistance and fire resistance.
• High durability, low maintenance required.
• Meet required standards such as QCVN 06:2022/BXD.

Disadvantages:

• High cost.

Installation procedure

Survey of duct and ventilation system

Before installing fireproofing, it is necessary to carefully survey the duct and ventilation system to determine the locations that need fireproofing. This helps to ensure that the entire system is effectively protected.

Selecting suitable fireproofing material

Based on the survey results, it is necessary to select the type of fireproofing material that is suitable for the requirements of the project. Factors such as working temperature, heat resistance level and insulation capacity of the material need to be carefully considered.

Installation of fireproofing

After selecting the appropriate material, proceed to install the fireproofing for the duct. This process must be carried out carefully to ensure that the covering material fits tightly around the duct and does not leave gaps, avoiding the risk of fire and smoke infiltration.

Periodic inspection and maintenance

After installation, the fireproofing system must be inspected and maintained periodically to ensure maximum fire protection efficiency. Maintenance includes checking the joints to ensure that there is no damage or wear during use.

Practical application

High-rise buildings

In high-rise buildings, fireproofing of air ducts is mandatory to ensure the safety of residents. High-rise buildings often have complex duct systems, so fireproofing must be done carefully.

Industrial plants

Industrial plants, especially those with high risk of fire and explosion, need to use fireproofing for duct and ventilation systems to prevent risks. Protecting the air duct system in factories helps ensure the safety of workers and production equipment.

Shopping malls

Shopping malls are crowded places, so ensuring fire safety is very important. Fireproofing for ductwork and ventilation systems helps prevent the spread of fire and smoke, protecting the safety of shoppers and employees.

Fireproofing ductwork

This is one of the important solutions to ensure fire safety for buildings and industrial works. The use of fireproof materials such as glass wool, mineral wool, and composite insulation panels helps prevent the spread of fire and smoke, protecting lives and property in the event of a fire.
