Product Details

The PF certificate refers exclusively to the time in which the flames are stopped from passing through (stagnation)
The homologation or certificate RF indicates the time, in minutes, in which the door maintains the four conditions: stability, stagnation, thermic isolation and absence of flammable gases.
Even though wood emits flammable gases when are exposed to high temperatures, this only happens on the side exposed to the flames, since the heat transmission to the other side is slow (the thermic isolation is very high). Because of that the most important fact on fire resistance in a wood door is the stagnation, which stops flames from passing through.
The time until one of these facts starts to fail is determinant on fire resistance.
Four basic facts on the fire propagation are: mechanic stability, stagnation, toxic gases emission and thermic isolation.
Doors between different rooms are critical points in case of fire, so they are carefully analysed.
One of the most important things in case of a house fire is to avoid or to contain, fire propagation through rooms.
