Firestop for construction joints

Our easy-to-use firestop products speed up installation and simplify inspection

Loading

To the trained eye, the quality of construction work is decided by the quality of its joints. Needless to say, joints are unavoidable – they exist to allow for movement between two building elements, be it floor-to-floor, floor-to-wall, wall-to-wall, head-to-wall, bottom-of-wall or perimeter wall. This adds up to countless gaps through which fire and smoke can spread.  

To help prevent the spread of fire or smoke within a building, certain walls, floors and joints are required to meet a specific fire resistance rating – the period during which a building component has been tested to confine a fire, or continue to perform a structural function, or both. This is where firestop comes in: blocking the gaps and penetrations in your structure is an efficient way to help contain fire, smoke and toxic gases. The construction is thus divided into compartments which are insulated from each other – a passive safety strategy which helps to prevent fire and smoke spreading beyond their origin.

Pre-fabricated sealing solutions

Closing a joint with our thoroughly tested firestop products not only makes your building safer, but also helps enhance performance in other areas. They meet the latest industry needs when it comes to sound insulation, energy efficiency, movement and seismic engineering as well as mold and mildew prevention. This is not only true for our firestop products but also for the sealants intended for non-rated wall and slab joints. To further improve jobsite productivity and safety, Hilti provides several prefabricated sealing solutions, such as our CFS-TTS top track seal. These easy-to-use products significantly speed up the installation process and simplify inspection.

Our fabric-free and low-VOC solutions help you create a healthier environment in your building, complying with respected green building standards.
