Insulating an interior chimney #green
I have a 200yr old 11/2 story cape in mid-VT. Over the years we have added insulation most everywhere and last year had significant attic and basement sill air sealing done. This past winter we still saw ice damming on the main part of the house. We heat with wood and have a woodstove connected to one of the flues in the central chimney. The chimney gives off significant heat into the unheated attic space. Is this a problem? Can I wrap it with mineral wool? Will that help? or should I quit using that flu in winter?
