Why fire containment matters

Understanding fire protection techniques can help save lives and safeguard your investment

The causes of fire outbreaks are varied, unpredictable and often outside the control of the building designer. This puts lives and assets at risk. What can be mitigated, however, is the effect of fire once it has started – through active and passive protection systems. Learn how Hilti’s expertise in passive fire safety worldwide can help support you in all phases of your construction projects.

Passive fire protection through building compartmentation

Effective fire compartmentation means sealing penetrations and joints in floors and walls using proper firestopping assemblies. These assemblies are a combination of fire-rated materials and firestopping devices. These devices, ranging from modular elements to putties and foams, help create a smoke-, flame- and water-resistant barrier which can assist in preventing a fire from spreading beyond the room where it starts.

Premium support for all building designers

Including fire protection early in the building design process is key to helping ensure proper installation – saving time and simplifying coordination. This is a complex task, even for experienced professionals. At Hilti, we offer technical support, approval documentation, design software and special trainings to simplify your work.

In-house testing for international approvals

At Hilti, we conduct thorough firestop tests in our in-house lab, following the most stringent international EN, ASTM/UL test standards and much more. Additional tests – including movement, seismic, acoustics and environmental – are carried out continuously on our pre-engineered, internationally approved solutions.
