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

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).

OK, so where would I buy some of these smoke pencils ?

Thanks all

Yup, "smoke pencils" are up to 3 bucks a pack, even more in "blue"
cities.

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.

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?

me know if you have posted also.

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$++

It seems to me you could do this yourself. To get that negative pressure
you'd have an exhausing fan tightly embedded in some orifice, be it a
window or door - probably easier to do in a window. You'd have to seal
all around the fan, and the stronger the fan, the better (up to a
point). Then you need something that emits smoke. IOW, get yourself a
"smoke pencil."

Many guys went wild when they found out a girl in a wet bathing suit
photographed as if no bathing suit when using IR film.
