The most important use of a grease duct wrap is that it helps us to vent the grease-laden flammable vapors outside a home or building. The maintenance of a grease duct is a very essential part. Everyone should keep in mind that all the fire codes and regulations are necessary while you are cleaning them. The risk of fire is significantly very high because the grease is highly combustible. Nowadays its use has become necessary in houses and buildings because it helps to prevent fire. Now we will discuss some different types of fire-resistant ductwork.
Types of fire-resistant ductwork
There are a total of four types of fire-resistant ductwork that can help you under fire conditions.
Ventilation fire ductwork
You can say that this type is either a supply or an extract duct. The main thing is that it undergoes a test for type A fire outside and type B fire inside criteria. Maintaining a cross-sectional area in fire is not necessary for this type of ductwork. The purpose of fire-rated ductwork is the compartment of the fire. In easy language, you can say that it avoids the spread of heat and fire between two compartments. If all the building materials and structural elements share a common fire classification then it becomes possible to avoid the spread of fire between two compartments.
Smoke extraction ductwork
A smoke extraction ductwork plays an important role in removing the smoke from buildings. It also helps in improving fire-fighting and flash-over prevention. You may have seen them in large compartments, car parks, and high-rise buildings. The car parks have a low ceiling which can be very dangerous because the space can fill very quickly. We can conduct the smoke outside the building with the help of fire-rated ductwork even using a fan-assisted system. If smoke ductwork is filled within a fire compartment then at east it should be capable of resisting the smoke temperature which occurs due to the fire.
Pressurization ductwork
The purpose of this ductwork is to restrict the smoke from different areas of the building. You can achieve this by making sure that the air in these areas is at high pressure than that in the adjacent area. You can see them in stairways, lobbies, and corridors as smoke inhibits escape. This duct can help the fire fighting shaft when they are serving deep basements because it clears the smoke.
Non-domestic kitchen extract fire ductwork
Another name for this duct is grease duct and you have to test it for both, type A outside and type B fire inside. These tests are compulsory as it is very important to prevent the flammable grease from catching the fire when it passes through the adjacent areas. Make sure to not use fire dampers in kitchen extract ductwork.
