Hi I want to run a 5" twin wall flue through a floor, from a wood burning stove. The room below is a living room with the stove, the room above is a bedroom. I understand that I need fire break between the rooms, usually that would be a plasterboard ceiling. But when shopping for a ceiling/floor plate for the flue to pass, all of them seem to be ventilated. I understand that the vent helps to cool any potential heat loss from the twin wall pipe, but surely this will breach the fire break. Does the ceiling registration plate have to be ventilated? Thanks, Guy

Hello all, I am an architectural designer. I am converting my 850sqft bungalow in the New Forest. Quite a major architectural change. I already have built a single storey rear PD extension, a natural pond, a timber frame garage, and a lovely barn in the garden. Since June I have been working on the main change to the bungalow by removing the roof and front walls, and adding a new 1st floor. My budget is very tight. Hopefully soon to be completed. I am loving the results. Guy
