Fire protection in tunnels is increasingly being pushed, not least because of some tragic accidents. The aim is to be able to use a tunnel again as quickly as possible after a fire event. The requirements are higher than for other standard fire applications, as these are hydrocarbon fires, which have a faster temperature rise and reach higher temperatures. Firemaster T board, manufactured by Sitek Insulation and distributed by Morgan Advanced Materials, which is related to the Batiboard product group, provides the required fire resistance. In comparative installation tests, it has been shown to be more efficient to work with than other materials because it is thinner, lighter and requires fewer anchors.
