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.

FF109 PVC VENTILATION DUCT FIRE SLEEVES
 
The FIREFLY 109 Sleeve has been developed to provide maximum protection for holes created by the introduction of the most popular sizes of PVC ducting with minimal installation time. In a fire situation, the sleeve expands internally to crush the duct and create an effective barrier against both heat and flames. Unlike other "intumescent" materials the FIREFLY 109 Sleeves do not need additional support and will only expand inwards.
 
Fitting Instructions
 
Step One
*Use the sleeve as template and cut a hole in the floor or wall to provide a snug fit.
  Step Two
If ducting is already in place then cut along the length of the sleeve with a sharp knife, opening the sleeve to wrap around the duct, repair the cut with the tape provided.

Step Three
If the duct is running tightly against the ceiling then the adjacent side of the sleeve can be cut away leaving a "U" shaped sleeve.
 
Step Four
Slide sleeve along the duct and into the cavity, ensuring that the sleeve has at least 25mm protruding from each side.
