"Hi John,
I work with a radiant barrier coating that can be used as an interior / exterior paint. Let me pass on something I have experienced that sounds identicle to what this garage is experiencing.
Radiant heat energy is going to enter the…"

Frost on Inside of garage walls
6 Replies
I have a customer that has frost forming on the inside of his unheated garage walls. I believe the cause is heat loss into the garage. I suggested he turn off the humidifier on the furnace and…Continue

Has anyone run into Dacotherm Attic Insulation?
2 Replies
I recently did work on a house that had this whitish foamy pebble like stuff for insulation in the attic. The house was balloon framed so it was also in the walls. I have never seen it before and am…Continue

I have a customer that we dense packed the attic floor of their house and airsealed around the masonry chimney. The problem is the red brick chimney condenses in the attic. This has caused the floor…Continue

John Nicholas replied to Phil Hanneman's discussion Frost on Inside of garage walls"How effective is the venting on the dryer, bath and kitchen vents? Do they effectively vent outside? Might run some CFM testing on them. See if what leaves is what went in. I would consider a ventilation fan in the garage if…"
Bud Poll replied to Phil Hanneman's discussion Frost on Inside of garage walls"We have only had a couple of frost nights so far in Bangor so figured you were out west.
Moisture in a garage is always a problem if you can't drain it off properly. Insulation and sheetrock may help hold the temp up a bit, but the…"
Phil Hanneman replied to Phil Hanneman's discussion Frost on Inside of garage walls"New York but close enough.
There are two bath fans and a kitchen fan, all properly vented. I didn't think about the snow from the cars as they do park two cars in there. I've proposed air sealing the basement and attic…"
Bud Poll replied to Phil Hanneman's discussion Frost on Inside of garage walls"You must be in a rather cold climate as I'm just shy of Canada and we just picked out tomatoes. I'm guessing Colorado. If it is below freezing outside, an uninsulated garage wall with no intentional heat will certainly be cold…"

I have a customer that has frost forming on the inside of his unheated garage walls. I believe the cause is heat loss into the garage. I suggested he turn off the humidifier on the furnace and control the RH in his house to help with the condensation. I also recommended insulating the rim joist adjacent to the garage with foam. The first room when you walk in to the house from the garage is a laundry room. Yes the dryer is vented outside. The attic of the garage was insulated by the home…See More
Nick Semon replied to Phil Hanneman's discussion Has anyone run into Dacotherm Attic Insulation?"Here's a link to the Popular Mechanics Advertisement for Dacotherm. Looks interesting. R4 per inch. Claims to be toxin free. What did the owner's think about their home's efficiency and the insulation?"
Brad Cook replied to Phil Hanneman's discussion Has anyone run into Dacotherm Attic Insulation?"A fuller description would be helpful. The adjectives "foamy" and "pebble like" seem to be contradictory. A photo or two would also be most helpful."
Phil Hanneman posted a discussionHas anyone run into Dacotherm Attic Insulation?
I recently did work on a house that had this whitish foamy pebble like stuff for insulation in the attic. The house was balloon framed so it was also in the walls. I have never seen it before and am wondering if there are any nasty chemicals associated with it. I also wonder if there are any health risks from handling it. I can't find a lot online about it. Any information would be helpful.
Steven Lewis replied to Phil Hanneman's discussion Chimney condensation in attic"The condensation is from the flue gasses condensing inside the chimney. This will be increase as the attic temp drops. ths cools down the brick which allows the flue gasses to condense out at a greater rate. If there is…"
Dave Dysson replied to Phil Hanneman's discussion Chimney condensation in attic"Is the chimney lined? It could be from flue gases from an unlined chimney. Any problem with condensation on the roof sheathing?"
Ben Stallings replied to Phil Hanneman's discussion Chimney condensation in attic"It seems to me the chimney is probably cold, being connected to the outdoors. So the moisture is coming from the surrounding air. If keeping moisture out of the surrounding air is not practical, I'd suggest insulating the chimney…"
Phil Hanneman posted a discussionChimney condensation in attic
I have a customer that we dense packed the attic floor of their house and airsealed around the masonry chimney. The problem is the red brick chimney condenses in the attic. This has caused the floor around the chimney to heave and the ceiling below to stain. The attic is 1260 square feet and is pretty leaky to the outside. The customer states the problem has only occurred since we did the work. Can any one give me some ideas what would cause this issue?…See More
