hello all,
I've got a fireplace that I never use in the 1st floor of a 2-floor
home
that has a flue/damper but
appears to let in lots of cold air. I tried to cover up the flue/damper
with a cap
and then tape it, but the cold air is still coming in.

Is there any way to seal this off properly?

The damper/flue (metal) appears to be closed, but feel lots of air
coming in.

Also, is there a good website that shows how to properly insulate
windows. I've
tried this on a previous home, but noticed air still coming in.

Thanks.


IIRC, a similar question came up within the last year or two. The answer
was a product that was like a special balloon, designed to inflate inside
the flue to block it off. It could be deflated and re-used. Also, the
material melted easily so if you lit a fire with it in place you wouldn't
fumigate your house.
