Evolution Tower in Moscow, Russia

Speedy installation of high-performance reliable firestop

Fire safety was a top priority for the building’s operator, who requested high-performance, reliable firestop. On the other hand, speed of installation was the builder’s main concern.

Apart from the scale and speed, the main challenge in this project lay in the complex local requirements for fire ratings in through penetrations: EI90 was specified for walls but EI240 for floors. Even with uncompromising performance requirements like these, the installer’s need for an easy-to-install solution still had to be met. 

CFS-D cable discs, CP 660 firestop foam combined with CP 646 wraps

Today, the Evolution Tower owes its passive fire safety to 32,000 CFS-D 25 cable discs, 35,000 cartridges of CP 660 firestop foam and 250 CP 646 firestop wraps. Before all this could be installed, close collaboration between us and the contractor, local regulators, inspectors and the building operators was needed.

The first step was to prove compliance with all the necessary requirements for fire safety – such as in the case of 100 mm walls and floors with an EI90 rating. Our technical department organized testing at third-party laboratories. As a result, our partners received official approvals tailored to their project applications.
Once the required ratings were achieved, four fire certificates were obtained for metal, plastic and ventilation pipes as well as for cable penetrations. Once the construction got under way, our engineering team was on-site to provide support during inspections.
The pre-formed, self-adhesive Hilti CFS-D cable discs provided a rapidly installed seal around small cables, bundles and conduits. For larger openings where both cables and pipes run through, CP 660 firestop foam coupled with CP 646 firestop wraps were used.

Regular presentations from us ensured that the contractor and building owner were fully informed when making decisions. Based on these decisions, our technical services department delivered recommended specifications, project documentation, organized project-specific testing and trained the installers on product use.
