Horizontal Firestop within masonry cavity wall
The CCL Cavity Firestop system is suitable for use with wall cladding systems . The performance of the firestop will depend upon the integrity and stability of the cladding system for the duration of the fire rating where required . Where there is a possibility of significant distortion during a fire , the cladding system must be attached to the structural floor , close to the firestop , with steel brackets . Due to the variety of cladding available , the system manufacturer should be contacted to confirm the suitability of its use with the firebarrier for the resistance period required .
- Firestop60 provides 1 hour fire resistance - Firestop120 provides 2 hours fire resistance .
Fixing :
sales @ concept - conversions . co . uk
Clips are required when the barrier is installed horizontally . They may be omitted during vertical installation if the barrier is supported at the base . The fixing clips should be bent into a Z shape and penetrate the firestop by over half of its overall width at a rate of 2 per length ( approx . 300mm from end to end ) The barrier should be securely fitted into the cavity ensuring it is compressed by approximately 5mm and the ends form a tight butt joint . The fixing clip should then be mechanically fixed to the floor slab or inner block work . Finally seal the joints with Class O aluminium foil tape .
