We are pleased to confirm that our Pacifyre® MKII Fire Sleeves and Pacifyre® BFC Fire Collar have now been officially tested and approved for fire sealing pipe penetrations through fire batts. Our products can be used with both metal and plastic pipes, and can provide up to a 2 hour fire rating – depending on the specific circumstances.  Our silicone and acrylic sealants were also included in the tests.

What are fire batts?

A fire batt is typically a stone wool board that has a high resistance against mechanical load.  Fire batts are often used to seal larger cavities in fire compartment walls and floors where pipe, cable trays, ductwork and other services are running through the partition.  The fire batt prevents the spread of fire and smoke, and can also be used on its own where there are no services passing through. pacifyre

How to install fire batts with fire stopping products

Make sure you do not see any bare stone wool.  The special coating and Pacifyre® A protect the stone wool and their binders from direct exposure to the flames.  Although most quality fire batts use specialized binders to improve their fire resistance over standard stone wool batts, this is still the weakest aspect in stone wool fire batts and they need protection to ensure fire rating.
