Currently, product safety and quality are two of the most sought-after qualities in the industrial and logistics sector. In this context, FM Approvals certifications are positioning themselves as a benchmark in the market, due to the strict criteria that validate their certifications, which exceed national regulations. FM Approvals is an entity belonging to the international insurance company FM Global, which is dedicated to analysing and validating construction products and systems to ensure that they meet demanding resistance, reaction, and safety criteria, with the aim of reducing risks in buildings used for industrial or commercial activities.

We are pleased to announce that HI-QuadCore 2.0 XT and HI-QuadCore 2.0 CT panels have obtained FM 4471 certification, a recognition that reinforces their position as advanced solutions for high-performance industrial roofing.

What are FM certifications?

An FM certification is a technical recognition that confirms that a product or system has passed rigorous testing, reproduces real-life risk scenarios and maintains reliable performance.

Some key standards for panels are FM 4880, FM 4881 and FM 4471, the latter being the specific standard for insulated metal roofing.

• – This is not a certification of the insulated product.
• – It is a certification of the system, i.e. panel + fixings + joints + installation method.
• – FM Approvals certifies the performance of the installed assembly.
• – The certification is not granted by the panel manufacturer, but by FM Approvals after independent testing.
• – All information can be found on the FM website via Roofnav.
  
  

What is the FM 4471 standard and why is it so important?

The FM 4471 standard applies exclusively to insulated metal roofing systems. It focuses on validating their performance in terms of fire resistance, wind resistance, walkability, and hail impact.

The HI-QuadCore 2.0 XT and HI-QuadCore 2.0 CT roof panel systems have undergone the following tests:

1.Fire performance tests: evaluation of the system’s performance when exposed to direct flames and heat on both sides of the panel. They evaluate:

• – How the insulating core responds to heat.
• – Whether the panel maintains its structural integrity. (Detachment of inflamed particles)
• – Flame spread.
  
  

2.Wind resistance: Simulation of extreme suction and wind pressure to verify the fastening and stability of the system. They evaluate:

• – There must be no detachment, fracture, or deformation of any component.

• – There must be no separation, permanent deformation, detachment, or fracture within the panel cover assembly.
  
  

3.Foot traffic resistance. They evaluate:

• – No perforation of the panel ceiling.
• – No separation or detachment of the side overlaps.
  
  

4.Hail impact: Resist the effects of hail. During this test, the coating is evaluated for signs of punctures, chips, flaking, blisters, cracks, or fissures.

5.Manufacturing audits: FM Approvals periodically audits factories to confirm that the same level of quality as in the initial tests is maintained.

 A step forward in innovation, safety and performance  

 With the FM 4471 standard, HI‑QuadCore 2.0 XT and HI‑QuadCore 2.0 CT panels reinforce their position as advanced solutions for high-performance industrial roofs. This certification not only attests to its superior performance in the case of a fire, but also provides essential added value for architects, engineers, developers and owners seeking maximum safety, durability and reliability in their projects.  

FM Approvals confirms that these panels meet and exceed the most demanding quality standards in the industry.

In the world of construction, fire safety is essential. Today, at Huurre, we are celebrating a new success in our range of fire compartmentation solutions. A historic achievement: our HI-QuadCore 2.0 FK DUAL panel breaks the ceiling of fire resistance certificates for organic cores, achieving an EI 120 rating for a thickness of 230 mm.

What does EI 120 mean? 

EI 120 is a classification that indicates that a building element offers fire resistance for 120 minutes, meeting two key criteria:

-E (Integrity): the panel maintains its structure without allowing flames or hot gases to pass through for 120 minutes.

-I (Insulation): it limits heat transmission, preventing the temperature on the unexposed side from exceeding the established limits. The average temperature must not exceed +140°C. At no point must it exceed +180°C during the entire 120-minute period. 

Results that exceed the standard

Although the official certification is EI 120, the test results are even more impressive.

If we analyse the exact result of the test passed, we see that the system achieved 136 minutes for thermal insulation (I) and 245 minutes for structural integrity (E). This information is reflected very concisely and transparently in the technical data sheet.

And what does this mean for the HI-QuadCore 2.0 FK Dual panel range?   

This solution provides high-level compartmentation for not only agri-food constructions but also for any industrial application. It prevents the spread of fire, maintaining its structural integrity and controlling the temperature on the unexposed side, and provides greater protection for people and materials for two uninterrupted hours.

Key benefits for your project 

 -EI 120 certified fire resistance 

-Thermal insulation: Conductivity λ = 0.019 W/m·K  

-Ideal for temperature-controlled spaces with compartmentation requirements 

 -Also applicable in logistics, industrial and residential settings 

Thanks to its QuadCore® core, this panel combines fire protection and energy efficiency, adding value to your project.

Fire performance of KS1000 AWP PIR core sandwich panels manufactured by Kingspan.

The fire occurred outside a large Audi dealership in Belgium in October 2014. It was an intentional fire.

The building is clad in a KS1000 AWP sandwich panel steel frame with a 100mm thick FM Approved certified PIR core manufactured by Kingspan and comprises a single-storey showroom and workshop and an internal mezzanine for additional vehicles at the rear.

Conclusions

• The PIR core sandwich panels suffered a fire that likely lasted at least 15 minutes after ignition.
• It is likely that the coating was subjected to a maximum incident radiative heat flux of at least 31.8 kW/m2 over a period of at least 10 minutes.
• Sandwich panels exposed to these conditions suffered damage to the level of delamination of the exposed steel skin of the panels, separating it from the PIR core, removal of the paint layer and pyrolysis of the PIR core material to a depth of approximately 40mm.
• There are no signs of fire spreading inside the panels.

A large fire occurred outside a furniture store in Presov, Slovakia – a large commercial building with a concrete frame and flat roof clad with Kingspan PIR façade panels. The building measures approximately 100 metres by 40 metres and is approximately 8.5 metres high.

The fire occurred in a kitchen area located approximately 4 feet from an exterior wall. The fire affected the combustible contents of the barbecue and 5 propane gas cylinders. At the time of the fire, the flames reached over 10 metres in height and directly affected the surface of the panels. más de 10 metros de altura y afectaron directamente a la superficie de los paneles.

Conclusions:

The fire was so intense that it managed to melt the aluminium composite panel used in the shop mascot sign in the short exposure period of 10 minutes.

There is clear evidence that the materials used in the construction of the shop mascot sign and the perimeter parapet light strip contributed to the spread of the fire and were the cause, according to the initial assessment by the fire brigade, of the external façade also being damaged by flames.

The core of the Kingspan PIR façade panels was charred to a depth of approximately 10mm in the area directly affected by the fire and the outer layer of the panels was peeled away from the core in these areas.

Despite the intensity of the fire, the Kingspan PIR core did not spread within the panel to areas away from the direct impact area of ​​the fire.

After extinguishing the fire outside the wall panels, the fire brigade found no signs of smoldering or flames inside.

The fire did not spread to the interior of the store. The effects were so small that the store was able to reopen about 3.5 hours after the fire.
