Efficiently firestop large areas with several penetrating items

Occasionally a cluster of multiple penetrating items will be grouped so closely that individual penetration systems cannot be used. In these cases, one single large system for multiple penetrating items is the most efficient solution.

The rectangular brick design of Hilti’s CFS-BL firestop blocks naturally fit in large openings and can be easily cut and modified in the field with minimal waste. The intuitive rectangular design virtually eliminates annular space between the bricks while the natural traction of the PUMA© material grips against other bricks and surrounding building materials allowing for easy installation, inspection, re-penetration, and maintenance. Additionally, the CFS-BL is compatible with other Hilti sealants to tackle the largest jobs.
