Cavity Barriers

PARAFLAM® SEB Vertical Cavity Barrier

Paraflam® is a perimeter fire stop designed for curtain walling and cavity barrier external rainscreen facades. Paraflam® is a non-combustible stone wool based product with a foil facing which prevents fibre migration and provides an excellent seal. It is designed to reinstate the fire resistance of a compartment, as well as offering good thermal and acoustic performance

 

Intended areas of use
• Masonry construction
• Curtain wall and perimeter facades
• External rainscreen facades
• Large horizontal and vertical joints in walls and floors
• Fire stop for internal apertures
