Ensuring that your home or business is safe in the event of a fire is an incredibly important task & so we take our job of selling safe fire doors very seriously. While practicality is a key feature of fire doors, here at Leader Online we like to make sure that you’re completely satisfied with your doors from the quality to the performance and of course the style. Fire doors, including internal fire doors with glass, work through the use of intumescent strips inside the door. These strips expand when exposed to heat so if a fire breaks out in your home, the strips expand and seal the room, preventing the fire from spreading further for a time.
What Is An Internal Fire Door?
Internal fire doors consist of a solid-core construction made up of particleboard, chipboard and/or solid wood timber. Another important part is the intumescent seal which is situated around the edges of the door. The main function of the seal is to expand when temperatures reach beyond 200°C. Internal fire doors play a fundamental role in fire safety as they block the spread of fire and smoke for a limited amount of time while they are closed, yet can also be used to mark fire exits so that you can ensure that you will be protected in any scenario you may find yourself in.
Internal Fire Doors With Glass
Fire regulations state that a fire door must be able to withstand a fire for a minimum of 30 minutes before allowing a fire to spread. To ensure that your fire doors are up to the task, we have chosen to stock fire doors that not only meet but exceed that expectation, with many lasting 60 minutes for an FD60 rating. Our collection of stylish internal glazed fire doors is no exception to these regulations & put through rigorous testing to ensure they meet these standards.
