James Hardie fibre cement cladding carries the highest possible fire rating: A2 s1-d0

In case of a fire, you want to know that the walls of your house will protect you while your family seeks safety. Fire feasts on wood, and it melts vinyl, or uPVC, almost instantly. But James Hardie® fibre cement cladding will not ignite when exposed to a direct flame, nor will it contribute fuel to a fire.

James Hardie cladding, weatherboards and building facades are made from advanced fibre cement material, which is non combustible, compared to wood cladding and uPVC cladding. With a high density and dimensional stability, fibre cement is naturally resistant to adverse events such as fire, extreme weather conditions, pests, rot and fade.

Our cladding is used all over the world, including fire prone areas where our products are specified to help resist fire attack from burning embers, radiant heat or flame contact. As the global leader in fibre cement technology, you can rest assured that when you use James Hardie cladding, you are using the highest fire rated (A2, s1-d0) facade cladding possible for a coloured exterior product.

Our non combustible boards have been extensively fire tested under the EN 13501-1:2002 suite of fire tests for CE compliance, which examines material reactions in respect of:

  • Direct flame applied
  • Heat transmission
  • Flame spread
  • Smoke production
  • Flaming particle emissions

All of our exterior products – HardiePlank®, HardiePanel® & HardieWindbreaker – perform extremely well in these tests, achieving the maximum fire protection rating for a coloured facade products. Our fibre cement cladding would not contribute to the propagation of fire.

2. Fire underway during a test (source is a propane lance)


3. HardiePlank cladding after exposure to fire. The carbon deposit (the organics in the paint coating flashing off) is localised and there has been no lateral spread of flame whatsoever. No significant combustion has taken place and no smoke has been produced.
