F Type Hinged GRP Door The F Type hinged GRP door is designed for use when fire safety needs to be taken into account. Dortek can offer F Type GRP doors from F30 to as much as F240. Dortek fire doors have a concealed intumescent strip. Having a concealed intumescent strip reduces the surface area on which bacteria can gather. The intumescent strip is activated under heat. Upon activation, the strip breaks through the surface of the door creating a fire seal. The one piece encapsulation means that the door is 100% waterproof.
