Application / Installation


QFVS Intumescent Fan and Vent Sleeves are simply fitted onto the spigot of the fan or vent and friction fitted into the plasterboard ceiling. The intumescent material expands in a fire situation to maintain the fire rating of the ceiling system.

This simple and cost effective solution can replace the more costly fi re dampers or the labour intensive boarding out of ventilation ducting.

This is a common problem in multi storey timber framed buildings, including flats, hotels, student accommodation and military barracks where mechanical extract ventilation system systems are required for en-suite bathrooms and kitchens.

QFVS Intumescent Fan and Vent Sleeves are designed to maintain the fire rating of both 30 minute and 60 minute floor / ceiling systems when penetrated by ceiling fans or vents.
