The Firefly 109 CE Marked Vent Duct Fire Sleeves provide 30 Minutes, 1 Hour, 2 Hours and up to 4 Hours Fire Resistance to rectangular PVC vent duct penetrations.

The Firefly 109 Vent Duct Fire Sleeves continue to be installed on a variety of Residential, Social Housing and Student Accommodation projects throughout the UK.

The Fire Sleeves have been full scale fire tested to EN 1366-3:2009 & BS 476. The European Technical Approval (ETA-12/0332) and EC Certificate 1224-CPR-0341 enables the range to be CE Marked and used throughout the EU.
The EN fire testing included ducts tested with Uncapped/Uncapped (U/U) duct end configuration as required for ventilation ducts.

The Firefly 109 Vent Duct Fire Sleeves are particularly suitable for use in plasterboard partitions, but can be used in blockwork walls and floors.
The Sleeves do not require any additional metal sleeving and are held in place by the plasterboard only. The unique intumescent material is vacuum formed to shape which ensures controlled sealing of the duct.
In addition the material swells externally to provide a fire and smoke seal around the sleeve.
