Insulation Contacting Furnace and Stove Ducts
I just installed blown in cellulose insulation in the attic of my home. As I was in a hurry to get the insulation installed, I forgot to install flashing around the furnace exhaust vent and the stove chimney to keep the insulation away.
My question is: Is it necessary to install shields to keep the insulation away if both the furnace and the chimney are of the double wall type? Both vents have an inner tube that is actually doing the venting and the outer tube that seems to be just for heat shielding purposes. Any pros that can weigh in on this one?
Thanks.
