Fire doors are an essential part of fire safety in many different environments. When things go wrong with a building during the outbreak of a fire, as we have seen with devastating effect with the Grenfell fire disaster for example, it can be really difficult to comprehend. The construction of fire doors when performed correctly will provide that extra layer of safety within a building, blocking a route for the fire and smoke and allowing time for people to get out of the building or to be saved before the fire can penetrate the door into that section of the building. Here, we take a look at how fire doors are constructed and what you need to look out for when purchasing and installing fire doors at a property that you are responsible for.
It is important to have the right type of fire door for a specific situation and location. FD30 fire doors are those that are built to withstand flames and smoke for at least 30 minutes, whilst an FD60 fire door will last for at least 60 minutes.
