What are Internal Fire Doors?

Internal fire doors are an essential part of any building’s internal structure, providing vital protection in the event of a fire. They help to contain and restrict the spread of smoke and flames, creating safe zones for escape or fire-fighting activities. An FD30 fire door is typically comprised of multiple layers of hardwood or steel, with a glazed panel in the middle. This helps to prevent fire propagation, while allowing light and visibility within a building.

When installing internal fire doors, it is important that the door meets UK regulations for internal fire safety and has been fitted correctly by an experienced tradesman. For instance, internal fire doors must be self-closing as this helps to contain the fire, and internal door frames must be fitted with an intumescent strip. This is a specially designed piece of material that expands when exposed to high temperatures, creating an effective seal against smoke and flames.

Another important factor when installing internal fire doors is the type of glazing used. It is advisable to use toughened glass which is designed to withstand extreme temperatures and provide greater protection in the event of a fire.

Overall, internal fire doors are an important safety feature that can help protect buildings from the spread of smoke and flames in the event of a fire. They must be fitted correctly by experienced tradesmen and should always include toughened glazing for maximum
