Fire doors and FR doors (fire-resistant doors) are technical doors that allow us to minimise the risks of fire and its propagation.

The ultimate purpose of these types of technical doors is to reduce the impact of an accident in a building. Fire doors and FR doors are particularly resistant to fire which means they take longer to burn and therefore lengthen the time needed by a fire to spread from one room to another.

And what are wood fire doors and FR doors like?

Normally, wood fire doors and FR doors tend to be thicker, they are made of fire-retardant chipboard and have solid wood edges that take longer to burn. In addition, some of the components of wood fire doors and FR doors are made of intumescent materials (which swell when exposed to heat) blocking any airways between rooms separated by these technical doors. This ‘sealing’ occurs with the fire doors and FR doors reducing the flow of oxygen that feeds the fire and preventing the flames from spreading rapidly from one room to another.

The most commonly used wood fire doors and FR doors have EI1 30-C5 (RF-30) and EI1 60-C5 (RF-60) certification under the UNE EN 13501-2-2009+A1 standard and are widely used in shops, hotels, hospitals, schools, health centres, etc.  For example, Spanish hotel rooms are required to use fire doors or FR doors with EI1 30-C5 (RF-30) certification. In other types of buildings and projects the use of fire doors or FR doors is determined by the architect according to applicable laws and the building’s security plans.
