Description

TENMAT’s FIREFLY 109+ Vent Duct Fire Sleeve LPs (Low Profile) provide up to 120 minutes’ fire resistance for all common PVC ventilation ducts. The Low Profile Vent Duct Fire Sleeves offer industry leading fire performance with low material thickness through the use of TENMAT’s expertise in high expansion intumescent technology.

The low profile design allows tight fitting against the ceiling soffit without the need to remove the top edge, aided by the compressible nature of the FIREFLY 109 intumescent material.

The product can be slit to allow retro fitting over duct work and the unique vacuum formed shape ensures that the product expands and seals the ducting in the event of a fire without the need for any additional metal cage or sleeving.
