What’s the longest fire rating we have even seen in the wood fire door scope? 60 minutes? 90 minutes? No, it’s 2 hours!
In the British Standard 476: part 22, 1987 it has clearly indicated how a 2 hours fire rated wooden door looks like. Now let’s take a quick a look at 2 hour fire rated wooden door specifications.
As mentioned in our previous articles the most important element is the core. The most common fire core we usually see is Halspan wood fire core, which is a solid composited fire rated particle board made by Halspan, British. This core is so amazing that almost all the fire door manufacturers in the world are purchasing fire cores from the Halspan, it’s stable, it’s nice and it’s standard. If we are using a Halspan core in a 2 hour fire rated wood door, the thickness of door slab will be 64mm which is really a very stubborn door.
But in ASICO we are providing another choice which is a mineral fire door, by which we can reduce the thickness to 57mm.
Besides, the frames will also be filled with fire cores in order to keep the door with good fire proof and stability.
At last, 2 hour fire rated wooden door would basically have same specifications with other common wood doors, they can be finished with veneer, painting or HPL. But don’t forget, the doors will have to be equipped with appropriate fire rated hardware.
