Chimney & Fireplace

Downstairs fireplace blocked off - Chimney still open to air - does it need a vent?

Anonymous user 03/03/2024 - 3.08 PM

Hi, We have a georgian house that is built around a stack. IE the lounge+ dining room have a fire hearth, as do the 2 bedrooms above these rooms. The flue in the lounge is in use as we had a wood burning stove installed. When the dining room was plastered - some mineral wool type stuff was placed in the chimney and then plasterboard was put over the hearth and then this was plastered over. As far as I am aware, the chimney stack at the top has not been blocked off. Do I need a vent in the plasterboard? Can I just block the top of the chimney to prevent any moisture entering? is the mineral wool stuff (cheaper insulation) a bad idea and needs to be removed? We have fires fairly often so I was hoping that the heat from one flue would warm the others up so that moisture would not settle. Thank you

IF you are concerned about your chimney breast becoming damp. you can cap the top of the chimney where it is open to the elements with a concrete slab. Or if the chimney pots at the top are open and are in good condition. You could also fit a chimney cowl or flu vent other wise know as an (elephants foot).
