Up to 4-Hour Fire & Blast-rated Certified Flammable Drugs Store for a Hospital in Johannesburg, South Africa! The Durasteel® firewall systems offer high dimensional stability with exceptional moisture resistance as well as being able to meet specified fire, acoustic, wind load, impact and blast performance requirements. Firewalls are used in constructions where high insulation and stability are required during a fire. Durasteel® insulated firewalls are designed to prevent the passage of heat from a fully developed fire on the exposed face. The maximum permitted temperature rise allowable on the surface of the unexposed face is 140°C as a mean temperature over the surface, or a maximum temperature rise of 180°C at any one point over the surface. Insulated wall constructions should be used in areas where the following may occur: - Escaping personnel or firefighters may have bodily contact with the wall surface. - If used as a wall lining to any escape route, for instance as an access tunnel within a factory. - If there are any volatile chemicals or materials stored within the vicinity of the firewall which may ignite at low temperatures. - There is a need to improve compartmentation beyond simple integrity. The combination of Durasteel® internationally tested characteristics makes the fire barriers, partitions and walls ideal for use in the most demanding application areas, including mining, gas and oil, industrial and commercial, providing up to 4 hours of fire resistance. All of Durasteel® fire barrier, partition and wall systems have been tested to both fire and impact resistance in accordance with international standards and BS 476: Part 22: 1987 with the added feature of testing to 3000Nm of impact both before and after the tests.
