Trying to seal up all the air leaks in the house. any tricks or suggestions on finding them ? there there I just cant pin point where they are coming from
Smoke would be good but not sure how to apply it.
Thanks
The most effective way is to find a company that will do a blower door test. They hook up a fan to your front door and put the entire house under negative pressure. All windows, electrical outlets, and any other place where air might leak is then checked with a smoke pencil. Since the house is under negative pressure, it highlights where any air leaks might be and they're easily noticeable with the smoke pencil.
If you're in Canada, you can request an EnerGuide for Houses evaluation (it costs around $150) which will include a blower door test. Details:
If you don't have a smoke pencil, a stick of burning incense will do the same thing (just be sure to pick a scent that you like).
Yup, "smoke pencils" are up to 3 bucks a pack, even more in "blue" cities.
OK, so where would I buy some of these smoke pencils ?
Thanks all
A blower door test is worth it you will get a person experianced on fining the leaks to show you, a printout of air exchanges per hour, Ideas on cures, and what you need in air exchanges to be efficient, usualy 2-350$ Or get a big fan and seal it in a door or window and test yourself, but you wont know how your house rates.
Corner convenience store or gas station. Ask for a pack of Marlboro.

Hi, Or IR picture using IR film. Tony
Or is you have a whole house exhaust fan, just cut it on to the low speed with the windows and doors closed.

A piece of cotton rope works good.
IR film in a regular camera will do nothing. Actualy many digitals are IR sensitive but consumer digital cameras and IR film are the wrong wavelength
Are you sure of that? Why do good cameras have a separate red? mark, near the regular mark, that is meant to be used for focusing when using IR film?
What do you mean by nothing? There won't be a picture? If there's a picture, how can it not be an IR picture?

I know it wont work to register heat loss with IR film , my numbers are a bit off but IR fim will register somewhere in the 700 nanometer wavelength range, for heat loss you need to go to 2000? NM range. Ive used IR film and am now experimenting with IR digital on my Sonys, Yes any? most? digital cmos are IR sensitive, there are just factory IR filters instaled some people remove, Remember the Sony IR digicam flap over "seeing" through clothes, a filter is involved. Many people now get junk digitals and open them up to remove the IR factory filters. IR in 700 MN wavelength is now easy to do unlike film was not. Actualy kodachome Slide film exposed but black is a IR filter, free in your old box of slides to experiment with your digital to see if IR is worth persuing. The Red area on the lens you are I believe talking about is IR focusing with IR film. Or the Red ring on a Canon is the Aspherical lens or high quality lens designation by Canon.
If IR was so simple there would never have been the need for 10000$ Thermal imaging cameras, you would only have needed a a cheap point and shoot and every body would do their own energy audits instead of having to pay the going rate of apx 300$++

costs around
You could, but the EnerGuide evaluation is more than just a test for leaks. I had one done a few years ago, and it was very thorough. The blower door isn't just a plain fan - it measures exactly how much air is flowing. The tech measured _exactly_ how much air was leaking, how many air exchanges were taking place in the house, and a whole lot of other stuff.
If you own a home in Canada, it's well worth the $150 to get the evaluation done. The "true" cost of the audit is about $300-$350, but it's partially subsidized by the government.
