Breakthrough innovation in Firestopping for top of wall applications

With the CFS-TTS Firestop top track seal

Firestopping drywall can be a laborious task - messing around with strips and backfilling with sealant.

CFS-TTS Firestop Top Track seal for top of wall applications simplifies this whole process to 3 very quick and easy steps: just apply the firestop to the drywall track, cut it to length and then fasten it in place - that's it!

This new firestopping method delivers a fire rated seal tested in accordance with AS 1530.4 and AS 4072.1, at the top of the drywall track to block smoke and fire for up to 120 minutes giving you peace of mind while saving you time in the process.

Firestopping for up to 120 minutes in 3 simple steps

The traditional method of firestopping top of wall applications with sealant is not only time consuming but also carries significant risk from working on ladders or on scaffolding. With the new CFS-TTS Firestop top track seal, this process is eliminated. You can get the job done up to 5x faster and work in a much safer way. 


Once the CFS-TTS Firestop top track seal is installed, there's no back fill required which means it's really easy to see that the installation has been completed correctly - saving you the stress of the inspection and making it quick and easy for the inspector too.
