What is the most effective way to protect this wooden construction from the spread of fire if the walls, ceilings and even the facade are combustible?
Internal simulations and analyses through research and development gave the following result:
A water vapour fire-extinguishing system using the low-pressure vapour extinguishing system EconAqua
The low-pressure water vapour fire-extinguishing system uses around 85% less water than conventional sprinklers. In the event of a fire, water damage will be kept to a minimum – a major consideration in wooden constructions, which suffer much greater damage as a result of fire-fighting water than, for instance, reinforced concrete constructions.
As less water is used, less room is needed to store water supplies
Fastening to combustible wall and ceiling constructions using double brackets developed internally
Key project figures
Largest wooden building in Germany with exceptional fire protection concept
Five-storey building, using solid wood construction techniques from the second floor upwards
Won the "sprinkler protected" award from the bvfa (Bundesverband vorbeugender Brandschutz, German Preventative Fire Protection Association)
Facts and figures on Caverion’s role
Around 700 sprinkler heads
Water supply of around 20 m³
Compressed sprinkler protection for the windows, to prevent flames from jumping from the facade into the rooms (and vice versa)
Ground floor divided into two fire compartments using a fire-protection curtain. Here, conventional sprinklers have been fitted using compression techniques.
