Baffling for Gas Tank Venting Pipe That Exits Through Roof Deck
This is an unfinished vented attic in Southern Ontario.
I am using a piece of Aluminum and high temp caulk to air seal the Gas Tank Vent Pipe coming through the ceiling, bought some Roxul to surround the vent and some metal lath to hold the Roxul in place. This way, I can use fibreglass on the remaining attic floor.
Problem is, I used foam baffles in the rest of the roof deck bays and the gas tank vent goes through the roof deck at the placement of the baffle. I can’t have the vent touch foam, right? Do I build a baffle for this bay? What material would be appropriate?
