Fire Performance

GammaStone AIR panels are NON FLAMMABLE, do not emit smoke, and have no drippings (burning droplets) when exposed to fire.  Consequently they are extremely safe in the event of a building fire. They meet all the requirements to be installed in ventilated facades as well as in interior cladding, in escape areas and in interior drop ceilings (Fire Reaction Class 1 attributed in accordance with UNI 9177). 

They have also obtained RINA MARED certification and can therefore be installed on ships. They have been subjected to 16 fire tests with results higher than those required by regulations in Europe, USA, and Australia. 

In Italy they comply with the Decree of the Ministry of the Interior of 15 March 2005 and the Guide for the determination of “fire safety requirements of facades in civil buildings” 

One of the most rigid and significant tests for ventilated facade installation is the NFPA 285 performed in the United States.  Our system was tested in an Intertek laboratory. Intertek www.intertek.com  is the world’s largest consumer technical testing group with a network of more than 1,000 laboratories in 100 countries. The test involves replicating a ventilated facade in all its components, setting a massive fire that escapes through the window below, and observing the reaction of the panels exposed to the flames for 30 minutes. 

In order to pass the NFPA 285 test, the fire must NOT spread to the upper floors, as soon as the fire is extinguished the panels must NOT continue to burn, and also the temperature on the upper floors must NOT exceed certain limits.  GammaStone panels passed this test. 

A very similar test which was conducted in England is the BS 8414.  It was performed at the BRE government laboratories www.bre.co.uk  and the methodology of the test is similar to the American NFPA 285.  Also here, to pass the test, the fire must NOT spread to the upper floors, as soon as the fire is extinguished the panels must NOT continue to burn and the temperature on the upper floors must NOT exceed certain limits. GammaStone panels also passed this test. 

 

NFPA 285 –  BS8414-1 

GammaStone AIR panels have passed the toughest internationally recognized tests for fire ratings, the American (NFPA 285) and the English (BS8414-1).  GammaStone is committed to supplying high quality, fully tested ventilated rain screen systems.  Our system passed the strict NFPA 285, confirming it complies with U.S. fire regulations for exterior panels installed on the building façade.  The GammaStone system also passed the strict BS8414-1 test.  Our material was installed on a concrete structure using an aluminum anchoring system for ventilated facades. The surface of over 30 sqm, which reached a height of 8.5m, was subjected to flames emitted by a 2m combustion chamber at the base of the wall. The “fire test” lasts a total of 60 minutes, of which the first 30 minutes is direct exposure to the flame. This test is considered fundamental for the use of building materials in UK, Middle East, Australia, and New Zealand.
