Ventilation ducting is widely used in both domestic and commercial buildings.

Both walls and floors are subject to fire regulations and must be fire protected in accordance with Approved Document B of Building Regulations.

Once a hole is made in a wall or floor for PVC ducting, the integrity of the construction and its ability to perform in a fire is reduced significantly, this must be firestopped to reinstate the original fire rating of the wall or floor.

The popularity of forced / controlled ventilation is on the rise as it can be much more energy efficient than traditional ventilation methods. The use of centralised ventilation units and heat recovery units, result in the building being subject to penetration holes both horizontally and vertically through the structure, creating pathways for the passage of both fire and smoke.

To combat this a range of FIREFLY 109 Duct Fire Sleeves has been developed.
