Fire behavior in sandwich panels

Huurre Ibérica has over 30 years supplying insulating panels with PIR core and Rockwool designed to obtain a good fire performance responding to our commitment to safety. Our company is distinguished in the industry by our philosophy of testing the panels against fire, ensuring optimum performance in case of real fire.

Huurre’s building systems are tested under assembly guides that reflect real scenarios, detailing each building element and providing the necessary accessories to facilitate assembly according to the requirements of each project. This approach, together with a thorough analysis of test results and fire performance certifications, ensures consistency and continuous improvement in building safety.

Not all insulation is the Same is our corporate philosophy of offering systems approved by external certifying bodies, while requesting real fire audits to document, transparently and objectively, the fire performance of our panels in real scenarios.


Reaction and fire resistance

The two most common parameters for determining the behavior of an insulating panel in case of fire are its reaction to fire and its fire resistance. Reaction characterizes the response of the panel when subjected to fire, and is important during the early stages of the fire. Resistance, on the other hand, is critical when the fire is fully developed and the panel must contain the fire to prevent its spread.


Discover the new Dual system

Dual System by Huurre

The range of DUAL sandwich panels offer high fire resistance, i.e., they have EI classification. Each Huurre DUAL sandwich panel, along with its mounting conditions, provides a sectorization in case of fire for a certain time. Consult our DUAL systems catalog and contact us for more details.

PIRM core

In 2007, as a result of an ambitious R&D project, HUURRE developed PIRM, a new formula that improves the performance of PIR. Panels with PIRM core have received the prestigious international certification , based on full-scale fire tests. Discover all the details in each data sheet or contact us for more information.

Analysis of real fires

One of the most convincing arguments for the use of Huurre Ibérica sandwich panels is the analysis of real fire cases that both Huurre and the Kingspan group have analyzed through independent agencies specialized in fire investigation.

Real Fire Case Studies from Huurre and other Kingspan Group factories have been independently investigated and have demonstrated the performance of the panel systems and their low contribution to fire. Over the years we have built up a library of real fire case studies, including the following independent fire investigations always carried out by an independent fire engineering consultancy.

General conclusions:

  • There is no evidence to indicate that the panels will increase the risk of fire spread.
  • PIR, PIRM or QuadCore cores were charred in contact with fire.
  • The fire did not spread inside the insulation core of the sandwich panel.
  • The PIR, PIRM or QuadCore insulating cores did not char in the non-fire zones.
