Fire Resistant Metallic Door

Home » Technology » New Technologies » Fire Resistant Metallic Door




Uninterrupted spread of fire in buildings is one of the major issues responsible in increasing the quantum of direct and indirect fire losses. Door openings, by necessity breach compartment walls allowing failure of integrity and insulation causing fire to spread uninterrupted. It is therefore essential to restrict spread of fire to achieve the required degree of containment. Failure to do so may cause considerable loss of life and property. A fire door with a specific -resistance rating is used as part of a fire protection system to reduce the spread of from one to other and to enable safe egress from a occupancy
