Please Help with How to Insulate a Sealed Chimney


Postby magaloo » Tue Oct 20, 2015 7:23 pm

My house gets really cold and I really need to insulate the chimneys.
I haven't got a lot of cash, I don't mind hard work and having a go
I have two chimney breasts where the fire places have been removed and plastered over.
Both chimney breasts start downstairs go through the first floor, through the loft and then above the roof.
The house is an end of terrace with the chimneys on the outside wall and both chimneys have air vents on the inside and the outside of the house
Should I just knock a whole in each chimney on each floor and fill it with something and then patch it up?
Could I remove a few bricks in the chimney stacks in the loft and pour something into it?
Is there any danger of the stacks collapsing if I do either of these?
Should I do something about the vents?

Please Help
Any help would be gratefully received

you cannot fill the chimney with anything as it will cause damp,
Its best to insulate around the breasting with either a polystyrene type wallpaper or foil back plasterboard
