Firestop for large openings

If you expect to upgrade or expand your M&E installations very frequently, preformed solutions – like firestop blocks – are ideal for easily sealing large openings. This non-curing and re-usable solution is designed for high-productivity installation by a single person with no special tools. CFS-BL and CFS-BL P firestop blocks have been designed specifically to simplify re-penetration of retrofitted cables. They can be dismounted, cut and re-installed easily. Firestop blocks also minimize airborne dust and fibers when compared to more traditional solutions like firestop coated boards and mortars

Our preformed, surface-mounted solution – the CFS-RCC rectangular cable collar – has been designed for firestopping mixed openings. Its modular design means that you can combine up to three elements together for the firestopping of opening sizes up to 562 mm. This easy-to-install and inspect, virtually dust-free solution allows for a 100% cable fill on regular and irregular openings. It also allows you to seal old, damaged or incorrectly sealed penetrations – even without removing the existing firestop material in the opening.

The CP 675 lightweight firestop board is also suited for frequent re-penetrations. Easy to install and cut, it is designed to accommodate single cables, cable trays and multiple cable configurations.

If you need to temporarily seal openings before final installation of the appropriate firestop solution, our re-usable CFS-CU and CP 651N firestop cushions offer great flexibility for cables, cable trays, conduits and plastic pipes for openings up to 1200 x 1500 mm.

If you will only occasionally be changing cables and pipes, our CFS-CT, CP673 and CP670 coated boards offer a wide approval range, including cables, cable bundles, cable trays, combustible and non-combustible pipes as well as multiple and mixed penetrations.

If you don’t expect to upgrade or change your M&E installations, then firestop mortars – such as CFS-M RG and CP 636 – are an economical solution for large openings. Mortars create a permanent smoke- and fire-resistant seal around cables, cable bundles, cable trays, plastic and steel conduits and various types of pipes (metal, PVC, PE).
