Hall of Shame
In this group, members share an array of images from the field, showing the kinds of issues encountered by home performance professionals in real homes. Each tells a story of how hidden (but fixable) problems in homes can cause high energy bills.
John Harper replied to Jonathan Bluey's discussion HELP - AIR SEALING a Continuous Stone Interior/ Exterior Wall"Hello. I have a large basalt stone floor to vaulted ceiling tall fireplace that also leaks. I have reduced my ACH to 8 from 12 and am now working on the fireplace. My plan is to caulk/foam (may be more economical) the whole dang thing…"

My home, built in 1990, has two vents (plus a hot water tank exhaust pipe vent and various leaks to the outside) located in the roof over an attic space above the connected-to-house garage. I know these vents (I think) should be kept open during the summer months but how about temporarily closing them or at least reducing their size during the cold fairly dry winter months. Winter-time temperature in this space can be about 30 degrees F lower than the 65 degree inside temperature of the home…See More
Robert D York Jr replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"The only part of the puzzle that you are missing is that the attic space above the insulation is outside of the building envelope. That being said, adding more insulation would be your best bet. Transition walls between flats and cathedral ceiling…"
John Harper replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"Robert, It is an education writing to and fro with you and others and I am very happy I found this avenue to pursue.
My garage ceiling is the same height as that of the mud/laundry room which runs due west from my attached garage and is about 14…"
Robert D York Jr replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"John,
In reply to your questions.... Where does one draw the line on R value in an attic? If I had room for an R 287 in my attic, I would put it there. When airsealing the top plates of the walls I like to use an expanding foam. Great Stuff will…"
John Harper replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"Thank you very much for your reply to my conundrum, Robert!
All off your points will be looked into -I especially liked your last sentence and believe it with the qualification that my home is reasonably plugged up in terms of holes to the outside…"
Robert D York Jr replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"Closing your vents, even temporarily, does not solve your problem of heat loss into this space. I would take a good look at the walls between the house and the garage. I would start by pulling back the existing insulation and airsealing the top…"
John Harper replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"Thank you, Sean. I am a newbie to the colds of Oregon and ownership of a home here in Bend. I will research the links you sent me and then get back to you when I have a better understanding."
Sean Lintow Sr replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"Yes indeed as it appeared your WH was in that attic before.
So a quick search shows you generally have 32" of snow a year & based on your description I doubt any of it stays on your roof long. I know this is going to throw a few of the pros…"
John Harper replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"Sean, I certainly could have better described my situation for you and I apologize for that. May I try again?
My gas hot water heater sits in my attached and un-conditioned garage right next to the walk-through door that opens into a…"

John Harper replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"Sean, Thank you very much for your response to my questions. I was working on a response to yours and hit a wrong button-away it went, I think. Let me know if you received anything from me and if not I will draft a…"
Sean Lintow Sr replied to John Harper's discussion Roof Air Vents Above Bend Oregon Garage Attic"So you have an unconditioned attic with a gas water heater which sounds like it is naturally drafting & you want to close up the air vents? I am not sure what you mean by spending money on heating that place unless you are talking about…"
