Description Recessed ceiling fans and ventilation ducts are widely used in both domestic and commercial buildings. Ceilings are subject to fire regulations and must be fire protected in accordance with Approved Document B of the Building Regulations. Once a hole is made in the ceiling for a polymeric fan or vent, the integrity of the construction and its ability to perform in a fire is reduced significantly. This must be fire stopped to reinstate the original fire rating of the ceiling. The popularity of forced / controlled ventilation is on the rise as it can be more energy efficient than traditional ventilation methods. The use of centralised ventilation units and the heat recovery units results in the building being subjected to penetration holes both horizontally and vertically through the structure, creating pathways for the passage of both fire and smoke. Unlike down lights, which are generally all fire protected, fans and vents are often left unprotected. A 100mm diameter fan or vent has several times the open area of a down light and does not even have a metal “can” to slow the spread of fire. This coupled with the ability of the fire to move all around the building via the ventilation system, makes it ever more important to fire protect all ceiling mounted fans and vents.
