FIRE RESISTANT DESIGN FOR MODULAR SUPPORT SYSTEMS

Fire resistant applications, codes and design

For over 25 years, Hilti has strenghtened its expertise in research and design of products able to protect against fire. We offer a wide range of fire resistant solutions, including modular support systems, fastening technologies and fire protection systems.

Our main goals is to give a concrete contribution for passive fire protection, and help people leave buildings quickly and safely in case of fire.

Your benefits

Safe

We care about people: in case of fire, main building exits have to be free, and Hilti elements connected to the roof are able to resist up and favour a complete evacuation.

Tested and certified

EN 1363-1 certified resistances, together with correlated ETA and CE marks, will provide you the best fire safety level for support systems.

Multifunctional

Hilti products and certifications are a seal of safety for MEP in all strategic jobsites.

Fire / Seismic / Corrosion-free

Our supports prevents corrosion, to protect your jobsite from both seismic and fire events. All the requirements you need to give your building a long-life resistance.

HOW TO BUILD FIRE ESCAPE AND RESCUE ROUTES

A correct fire protection design model has to ensure that residents would have enough time to leave the building safely in case of fire.

The German guidelines MLAR [4] (current version 11/2005) describe how to keep escape routes free and how long: for example, the required fire resistance for fire rated suspended ceilings must be guaranteed in the event of a fire coming from above and below the ceiling.

Special requirements must be observed for modular support systems that are installed between the structural ceiling and the suspended ceiling.

KEY EUROPEAN STANDARDS

EN 13501 and EN 1366-1:2104 are some of the key shared European standards describing fire resistant design for ventilation ducts and smoke control. In addition, the German MLAR directive underscores the importance of fire safety in ventilation systems.

Section 5.2.2 refers to the ventilation lines, which need to be fire resistant, and states that the fire resistant line sections have to be fixed with corresponding fire resistance building components.
Section 5.2.4 mentions ventilation lines above suspended ceilings by pointing out that, if ventilation lines are installed above fire rated suspended ceilings, such ventilation lines have to be fixed properly to avoid their collapse in case of fire (see DIN 4102-4:1994-03 [6], chapter 8.5.7.5).
