We are a business that focuses on keeping its clients safe from the dangers of fire. With our support, people in the building will be in a much better position in the event of an incident. One area we cover is the specification and installation of fire rated walls and ceilings. These elements are essential for halting the spread of smoke and fires through buildings.

Fires in commercial and residential buildings in the UK do a lot of damage every year. As a result, you should think about how your walls and ceilings could protect you. It is true that no practical building material is 100% fireproof. However, a well-constructed building can help to stop tragedies.

How long will it take?

Smoke alarm in a modern building

The question here isn’t whether a fire can harm a building. Rather, it is a matter of when. However, fires take more time to act against fire-resistant substances. What you should do is choose materials where fires take effect slowly. They can ensure that occupants will have enough escape time and make it safer for emergency responders to do their job.

We rate materials in relation to how long a fire would take to influence their structural abilities. What we will be doing here is discussing some potential options you could use to improve safety.


This is one of the most common building substances in the world. Luckily, it is also very fire resistant. It is a non-combustible material and comes with low thermal conductivity. Thus, it will take some time for fire to influence its load-bearing, structural capacity. It safeguards against the spread of fires as well. If you compare to steel, it is far more fire resistant.

Something we must stress though is that the properties and fire performance of concrete can differ depending on a number of factors. Most notably, the specific varieties of aggregate substances can change. Aggregate can account for 60 to 80% of the concrete’s volume. The precise fire resistance characteristics depend on the level and type of aggregates.

Concrete is considered to be one of the leading fire resistant building materials. It is a good option for the roof and ceilings, especially when it comes to fire protection. Give us a call if you need help with fire rated walls and ceilings.


A number of structural materials shall demand underlying gypsum sheathing. This is to acquire a good fire resistance rating.

Gypsum board is one of the most common options for a fire resistant interior finish. Also called drywall, it includes a gypsum layer between two paper sheets. The board includes a combustible core, which holds chemically combined water. When the fire affects it, the water comes out at steam. Effectively, it hampers the heat transfer through the material, resisting fire penetration for some time. To increase fire resistance ratings, people can use several gypsum board layers.


Finally, there are bricks. They are highly resistant to fire because they are made in a kiln. As a result, they get exposed to a high level of heat and can offer really impressive resistance.

However, there is an important thing to note here. While brick is highly fire resistant, the mortar that holds bricks together in walls has lower resistance. You need to keep this in mind.

Regardless, people constantly call brick one of the top building materials for fire protection. Brick walls have the capacity to obtain one-hour to four-hour fire resistance ratings.

We work closely with clients when they need fire rated walls and ceilings

At Trident Fire Protection and Training, we have been offering our services to the UK for a long time. Our team works closely with every client to ensure we understand their needs and meet them.

Clients can call on us for help specifying fire rated walls and ceilings. We can suggest the right materials to offer the level of protection you need. Then, we can provide installation and testing. So, if you need something from us, feel free to get in touch.
