Economy Intumescent Letter Box With Intumescent Liner
Intumescent letterboxes are mainly used on the doors of flats, so that in the event of a fire in the flat, the fire would not spread onto the hallway escape route.
Our Economy Letter Boxes are ready to install in mail apertures, replacing the existing standard letter flaps.
The economy letter boxes have a plastic bodied black frame, aluminium face plates, complete with smoke, weather and draught seal. They also have an intumescent seal fitted round the body of the letterbox to crush and seal in a fire.
