Hope someone has this info:
1 - What is the r-value range of an insulated flue (metal liner)?
2 - I have a masonry chimney with an uninsulated metal liner inside it. We are renovating the house and in doing so will be adding 2 inch foam (R10) on our outer walls. I am wondering if insulating the outside of our masonry chimney would have the same effect as insulating the liner.
Cheers
François
