How Vermiculite Plaster Helps for Fireproofing

By Ian MacOlive


Several compounds have been introduced in the market in the last few years that help in fire protection, enhancing the safety of a structure. Vermiculite plaster is one such material that is often used on the walls of a structure to increase its ability to retard flames and prevent a full blown inferno. Here is a look at what this substance is and how it can help you to protect your facility or building.

As the owner of a building, you might be worried about protecting the structure against damages caused by a fire. Depending on the severity of a fire, serious and permanent structural damaged could result in significant losses.

Fireproofing is needed at both the active and the passive level. You will not only need to have fire extinguishers, smoke detectors and water sprinklers which can help to control the fire but also a passive system in place that prevents the spread of the flames.

What is vermiculite plaster?

Vermiculite is a naturally occurring substance that reacts to fire the same way that some of the commercial fire protection products do. When it is exposed to heat it expands, decreasing in density and increasing in volume. Because it will prevent flames from spreading quickly, it helps with evacuation and rescue efforts. Vermiculite plaster helps protect the walls against high temperatures that could potentially cause structural failure.

How is vermiculite plaster used for fireproofing?

While vermiculite products are available in the form of panels and boards, vermiculite plaster that's sprayed on is commonly used for passive fire protection. This material is light weight and possesses superior insulating properties to help control the temperature if a fire does occur.

Vermiculite plaster has several applications in passive fire protection systems:

Effective against cellulose fire: A low cost vermiculite plaster spray is used on structural steelwork and for internal application in commercial buildings. This helps to protect the integrity of concealed steel in the structure as well as in the car park areas.

Hydrocarbon fires: The naturally occurring compound can withstand very high temperatures like those associated with hydrocarbon fires. So, it can also be used in the petrochemical filed. It is well suited to application in alchemical plant steel work, LPG vessels etc.

The benefits of using vermiculite plaster

Lightweight and versatile material. When vermiculite and Portland cement are combined, the mixture can be substituted for ordinary concrete mixtures to provide superior fire resistance and insulation. This material possesses occurring substances that have fibers that expand when exposed to extreme heat. This low cost vermiculate plaster spray is colorless and odorless, making them nearly invisible as they provide fire protection. This material is available in the form of PPC and gypsum for decorative applications. Additionally, this compound is available in the form of textured spray finishes that are applied to the wall on top of a base coat of tinted material. It looks stunning and affords all the passive fire protection that you need.

Vermiculite plaster plays an important role in fireproofing a building. Not only does it provide the protection you want and need, but it will enhance a building's appeal to renters and buyers.
