Installing Fire Doors
February 15th, 2010
Obstructions which may hinder the rotation of the Fire Doors like wedge door stops, hookbacks, chains and hinges must be lubricated frequently. Listed door hardware should be installed; one will risk prosecution otherwise. Steel bearing-type hinges are compulsory and recommended. Although, steel hinges which are plain and non-bearing can be implemented which form a specific assembly. Conjugated doors which need astragals must have at least a single overlapping astragal. Doublets of doors which are within means of outlets mustn’t be installed with such an astragal that stops the unhindered application of a leaf. To ensure a complete closing, a coordinating unit or open-backed strike is recommended. The glass frame, as well as the glazing-bead must be of high quality metal, if the door has a glass frame built in.
