BOSS fire listen to customer feedback and develop systems that are easy to install, cost efficient and ensure compliance, every time.

Due to heat transfer of a steel pipe this size, in the past a more common solution would’ve required a thermal wrap of some kind in addition to a fire stopping sealant. Well not anymore, we’ve developed a system for up to 60.3mm OD Steel Sprinkler Pipe using only BOSS FireMastic-300™.  Simply use a 50mm x 50mm surface fillet of sealant to either side of your wall to achieve up to FRL -/120/120.

BOSS FireMastic-300™ intumescent Fire-Rated Acrylic Sealant is a one part acrylic emulsion that is designed to resist the passage of fire, smoke and sound. FireMastic-300™ will intumesce and form a char when exposed to the heat of a fire, which will prevent the passage of fire and smoke for up to 5 hours in both integrity and insulation. FireMastic-300’s superior acoustic properties means it offers up to a 63dB sound reduction, making it ideal for high performance acoustic installation.
