Fire Integrity: 240 minutes
Fire Insulation: Up to 240 minutes
Durasteel insulated fire barriers are used in constructions where high insulation as well as stability is required during a fire, and are designed to prevent the passage of heat from a fully developed fire on the exposed face.
Our insulated fire barriers can be designed to provide anywhere from 60 minutes (1 hour) thermal insulation up to 240 minutes (4 hours), with a maximum permitted temperature rise allowable on the surface of the unexposed face of 140°C as a mean temperature over the entire surface, or a maximum temperature rise of 180°C at any single point on the surface.
