Fire Doors and Glazing
For a structure or door to be fire resisting it must be able to resist the passage of fire, heat and smoke for a minimum of 30 minutes and meet with the relevant parts of British standard 476.
Doors fitted within fire resistant walls should comprise of a fire resistant doorset, i.e. door and frame conforming to BS 476: part 22 and or 31. The standard of fire resistance of doors can be improved by the use of intumescent materials on the edges of doors and/or frames.
A panel of clear glass may be provided within the door or adjacent partition. It should be of an appropriate size and in a suitable position which gives the occupant of the inner room early visual warning of fire. All fire resistant glass should be in compliance with BS 476: Part 22 (min ½ hour)
