Creating firestop conditions across a large opening is one challenge. Accommodating diverse sizes and shapes of penetrations is another. But configuring large firestops that can adapt to frequently changing configurations is the most challenging of all. That’s why Hilti firestop experts designed a versatile, building-block solution for all three scenarios—the intumescent Firestop Block CFS-BL. These non-curing, reusable blocks can be cut to fit custom openings and installed with no mess, special tools or compression required. They can be used in floors or in one-sided installation of wall systems—and for temporary or permanent sealing of single or multiple penetrations up to 12” annular space.
