    Sorry its not protecting the fan I'm intrested in. But its air/moistuer moving between the bathroom and roof I am looking to prevent, I thought the building and IEE regs say you have to seal any gaps to prevent movment (and fire) of moisture.

    Moisture sealing and extraxter fan into a roof

    Thanks for reply. My confusion is the class 1 lights I have also have a smooth finish that should create a close fit to the plasterboard. But to create a seal against moisture and air movement they come with a gasket. The Ion will have a gap between it and the hole cut to insert it through...

    locating a fireplace opening

    No, mainly as I have no idea where to start to do so. Clearly the fire place must be on the side of the room away from the living room stack but that’s not much help! There is also the dual problem that walls are stone rubble, some 18-22 inches thick, and the plaster is not in good condition...

    locating a fireplace opening

    We have two chimneys and one fireplace in use. The in use one is central in the ground floor room with equal sized alcoves on each side with the chimney in the centre.
