Runehamar Tunnel Fire Tests - Uptun: Fire Protection

 High-performance product
|
 |
A new generation of high performance products - PROMATECT®-T - was launched with multiple advantages for the protection of concrete structures, construction of escape routes, fire doors, cable systems , ventilation systems. |
|
Designed to answer all but including the most severe fire scenario as described by the RWS fire curve, this product is not only a barrier to fire or a kind of ceramic protection, but for a certain period of time plays the role of a fire brigade by cooling down in pre-designed steps the near environment of the board. Afterwards becoming an efficient thermal insulator at fire temperatures up to 1400° - 1500°C . |

The engineered matrix products can easily secure a same temperature value at the interface with a concrete structure only with half of the other products thickness (figure 2). |
|
Although designed as panels, the engineered matrix allows curving on site of a board to cover surfaces with a diameter of curvature down to 8 meters (figure 3). Easy to install by clean techniques (figure 4, Toulon tunnel), the application of the engineered matrix products can be realised on existing tunnels without total neutralisation of the traffic. |
