Insulating disused chimney

Luckysasha

We have 4 chimneys in our house at the moment. When we renovated 5 years ago we blocked up 3 of the fireplaces leaving no trace in the rooms. The only remaining working chimney is in the sitting room. Last winter 2 of the bedrooms with the blocked up fireplaces felt very cold and hard to heat. The chimney's are still open at roof level. Is there someway to insulate these disused chimneys to keep the heat in the rooms. Is there something like a fill material I could pour in from the top to fill the flues up before capping them.

What did you block them with?

Chimney balloons are probably your best bet, tbh.

Edit: just saw you don't have access to the fireplaces anymore. Not sure what to advise here, tbh. Ring an insulation specialist and ask?

Thanks for that. The fill material seems to be along the lines of what I was thinking but I worked it out at €500 to do what I need. I blocked the fireplaces up with plasterboard what about drilling a hole and pumping in some expanding foam or cutting up fibreglass insulation and shoving it down the flue from the top. Labour intensive I know

And a hoor of a job to undo if you sell the house and the buyer wants to reverse the work.

Not really something I will have to worry about !!!!! Just looking for ideas on a way to do this

You sure the (blocked up) chimneys are the problem?
