Very large residential and commercial structures, including logistical warehouses, data centres and high-rise buildings, are becoming increasingly common in cities and towns all over the world. 

At the same time, the risk of fire in these buildings continues to be a cause for concern1.  Compared to the 1950s, fires in modern structures can develop much, much faster – as the combustible load in buildings is now much higher. 

ROCKWOOL structural protection products are designed, engineered and tested to keep steel and concrete – two of the most popular materials for large constructions – protected against fire.

The stone wool used at the heart of every ROCKWOOL product is a natural fire barrier, while our dedicated fire range is especially designed to maximise this protection. 

This can make the difference between a building containing a fire, to being on fire itself.

Why do we need structural protection?

Steel and concrete structures require the utmost standards of protection against the risk of fire, for the safety of their occupants as well as the surrounding buildings and people. 

Steel is a sturdy and stable material, but at temperatures above 500°C it loses its structural integrity. As the backbone of a building, exposure to temperatures this high could cause the building to collapse. A normal fire in a building can initiate temperature rises from 20 to 800°C in minutes.

The safety of a building’s occupants is paramount in case of fire, and every second counts. By adopting adequate fire protection, it’s possible to hold off structural disintegration, buying more time to evacuate safely and for fire services to find and fight the fire.

Maintaining the structure of a building during the event is also important. By containing the fire and preventing collapse, the building and its surroundings can be saved.

Calculator and savings

Effective structural protection can prevent a building from suffering severe damage, or even collapsing. Its ability to safeguard human lives, meanwhile, is invaluable.  

When it comes to fire safety in large buildings, there is no one-size-fits-all approach for achieving the correct specification.

We have detailed fire resistance and application data that outline solutions required to provide effective protection.

Our fire resistance solutions will significantly reduce the risk that there is not enough time for occupants to leave the building. Not only by preventing the spread of a fire, but also by not contributing any significant toxic smoke – as smoke inhalation is the most common cause of death in house and building fires. They also allow the fire brigade to control the fire without the building collapsing, as we can offer increased fire safety of up to 240 minutes

Case studies

The Centre, which is located between Edinburgh and Glasgow, is a Land Securities shopping and leisure destination that has undergone three phases of expansion since the 1970s. The goal was to extend the original building and transform it into a striking landmark that was environmentally sound and completely safe.

 

The challenge

The new part of the building had to be suspended over an existing road which meant that fire protection was of utmost importance. The aesthetics of the underside of the structure were also a key consideration.

 

The solution

ROCKWOOL technical experts worked with Threesixty Architecture to produce fire calculations to meet their fire engineering strategy requirements for the 70,000 square foot development. A series of products were specified, including ROCKWOOL BEAMCLAD®, which was utilised as it is suited to a diverse range of modern steel constructions. It delivers outstanding fire protection, is quick and simple to apply and requires no maintenance.

 

The results

“Effective product performance, ease of installation and cost-effectiveness were key in this project and all of the ROCKWOOL and ROCKPANEL products met this brief. The BEAMCLAD® and Hi-Impact Soffit Slab boards were also lightweight and we had additional support from the factory.”

FAQs

FAQs

What is fire stopping?

Fire stopping is the process of stopping and slowing fire spread throughout a construction, by installing effective fire resilient products – including fire insulation. The ultimate goal is preventing the spread of fire to ensure a safe exit for occupants. Find out more with our fire stopping page.

 

Are ROCKWOOL products non-combustible?

ROCKWOOL stone wool insulation products are inherently non-combustible. Stone wool can resist temperatures up to and in some cases over 1,000°C, and work to prevent fire spread.

What is the melting point of stone wool?

ROCKWOOL stone wool fibres can withstand more than 1000°C without melting. They also don’t emit significant amounts of toxic smoke when burning, which is the cause of 45 percent of fatalities6 in fires.
