HILTI CFS-BTS Bottom Track Seal
Product description
- Preformed firestop solution for bottom-of-wall drywall joints — helps increase productivity on the job site and eliminate the need for slower, messier sealants.
Applications for use
- Firestop, smoke, and sound seal for the bottom of the wall joints between bottom track and drywall to flat and metal deck concrete slabs
- Tested and UL classified with standard 1-hour and 2-hour partition walls, resilient channel walls and shaft walls (5/8” and 1-1/4” available).
Advantages
- Easier to install under real job site conditions — compressible firestop joint seal suitable for installation in temperatures as low as 14°F (-10°C)
- Higher productivity — the preformed firestop replaces 5/8” drywall shims and works with kick-lifts to help save time and improve quality control of drywall install
- Zero waste — controlled material cost / easier to bid
- Sound and Leakage-rated joint seal — CFS-BTS firestop can provide STC ratings for fire/sound walls, and has been tested in accordance with L-rating compliance in smoke barrier walls (IBC)
- Compliance with LEED green building regulations provides industry-leading low VOC, LEED 4.1, and Red List (LBC) compliance
- No skilled labor required and may not be subjective to destructive testing.
