Hello! I've got an old fireplace in my house that the previous owners had a gas fire fitted into. The gas fire was a back boiler, so they had a metal chimney fitted inside the existing brick chimney, to allow venting of steam/vapours I believe.
The external chimney has a cap/cover fitted. See pictures.
The inside, I've put some loft insulation inside the metal chimney liner to avoid drafts (see pictured)
This has been fine for a year, but I've noticed some wind noise over the year. Tonight, with the heavy winds a load of old soot/brick fell down into the open fireplace.
I'm trying to work out how I can prevent this in the future (both avoiding falling dirt and drafts) without causing the chimney to become fully sealed and a source of damp.
Is it a simple job to put a board inside the chimney at room level to block the chimney, or is there a more involved process needed?
