A Hilti firestop expert was contacted by the M&E planners after a Hilti presentation on firestop in wood during the Firestop Academy in Berlin. From an early phase, the firestop expert was in contact with the planners to craft a firestopping solution for waste water, fresh water and heating pipes, as well as electric cables going through a single opening in a 90-minute fire-rated wall.
Based on official fire tests conducted by Hilti, the expert designed a project-based solution and provide an engineering judgement. Hilti CFS-BL P firestop blocks were specified as a solution to seal the large opening with mixed 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.
