Andrew, sorry for getting distracted at the end of our conversation. The power kept going off and on, and of course no one around here can handle anything that comes up during the day that is out of the ordinary.
Another issue I read about when doing this is some of the fog machines use a solution that is oil based. By using the fog and a blower door to pressurize the structure you could be putting oil in places it probably should not be.
However, there are water based solutions from what I hear.
Here is a video of it
The picture on the bottom of this page shows it being used with a duct blaster
I do not remember where I read about this application at originally, but the person that did the test was using it prove to a general contractor where mistakes were made in the structure that the GC built. He said that when he turn on the blower door smoke started pouring out of the house. The GC walked away and had someone out to the house in a day fixing the problems. I guess the visual of doing this is pretty impressive.
I have the same fog machine they show at the bottom of the page. it is an oil that the unit uses. I would want a damage waver from the owner be for I Used that in same one in a home. A fine art work or some Lady’s nice dress, or other items that can be found in a home could be damage beyond repair or clenning…
I don’t think my insurance would cover any of this…:shock:
The fog does leave a fine film… and has a smell. My wife has Asama and she can not be in a room with that stuff… the air is to thin for her.
Sometime these machine will spit and sputter and drops of oil can come out the spray tip… You would wand to set is up in and air without carpet or floor coverings… I use this at shows we did with my band… sometimes
people would step away from the stage so we stop using the fog machines…
I could see it being used in a new home with no sheet rock but not in a nice home.
You mite think about dry ice and water much better program only has the ammonia smell for a short time.
Hi all. I’m somewhat new to these forums. I’ve enjoyed what I have learned thus far from all of you guys.
I had RESNET training last summer and became a HERS Rater through that. On our day in the field, I got to see a fog machine in action. It was used in a house that was being qualified for the Energy Star label. It pinpointed the leaks in the duct system wonderfully. By the way, these machines should be used in the duct system only, not an entire house.
I agree 100% on the duct system fog machine test. I think for the entire structure technologies like IR are better suited. IR still has the same visual effect for the home owner or any one else involved. However, with duct systems generally harder to access with IR and made of low E value materials, smoke is a much better option.
