GLAS-DOR fire resistant steel sections have been tested in accordance with BS476: Part 22: 1987. Wall sections offer up to 120 minutes integrity and insulation, doorsets up to 90 minutes integrity and 60 minutes insulation. Double leaf sliding doors are not currently available with fire resistance.
Door and wall sections make up the fire cell partitions in, for example, corridors, main passageways and stairwells used as evacuation routes in the event of a fire. The solid fire-resistant insulating core between the steel profiles effectively reduces heat transfer from the side of the door or wall exposed to the fire.
