To make sure that the strict fire protection requirements are met, Hilti conducted a joint fire test together with Lignotrend. All the mechanical and electrical penetrations designed for this building were tested with the right firestop solutions on a Lignotrend floor. With strong fire test evidence, Hilti Firestop Specialists convinced the architect and the local authorities about the fire performance of the system.
In this project, there were many waste water services in non-standard configurations, e.g. corner applications. For these applications, Hilti CFS-C EL firestop endless collar was used. It has a wide range of approvals for various pipe configurations, including elbow pipes, inclined pipes, and pipes in corners etc. For the electrical cables, conduits were used that were passing through a large opening. Hilti CFS-BL P firestop blocks were selected as a solution to seal the large openings with the cable penetrations.
CFS-BL P firestop blocks come with a broad range of approvals for mixed penetrations, as well as being fast and easy-to-install. As a preformed and ready-to-use product it also helps reduce overall construction time. Also, it provides high acoustic insulation and carries the Hilti Clean-Tec logo, which stands for more environmentally-friendly Hilti products.
