I didn't mean that there was actually a stream of cold air (which
there isn't) just the knob itself is freezing cold probably
because it is made of steel. I figured filling the gap with
spray foam or replacing the bezel with a wooden one would solve
the problem.
If you disassemble the lockset, you'll find that the metal outside
knob is fastened to the metal inside knob with metal screws. The
locking mechanism also connects to both knobs, just not as solidly.

To stop heat from flowing from the warm side to the cool side,
you'll have to have a "thermal break" between the two sides--some
non-metal material to which both sides attach.

This non-metal thermal break is not available as far as I know, and
I bet it never will be. It would be a weak point in the lock, and
you want a lock to be as strong as possible.

The heat transfer will be small in any case.

If you're interested in saving heating/cooling money, you'll be
better off looking for something else to improve. If you want to
avoid touching a cold doorknob, get somebody's grandmother to knit
a doorknob cozy.

Hint: Don't waste your time saving money on your doorbell. ;-)

I feel like this posting can be useless. All I want to know is if
someone has ever insulated a door knob. That is it. Not if you like
knitting knobs, not if you are confused if this is a really post or
not, not your personal opinions on gmail, not anything but what is in
the original post. If the original post is not clear then ask for
clarification or don't post at all. Ron and Don had the only good
posts and I would like to thank them both very much for making this
particular thread worth while. I think the rest of you seriously need
to get a life!


I'm sorry. We didn't know you just wanted an answer without any
justification, explanation, possible alternatives, conversation, or
camaraderie.

The answer is: No one has ever insulated a doorknob.

And to answer your other question upstream about Google Groups (which is
NOT the same thing as Gmail), this is a good example of why people look
down on it. Your most recent post came through 5 separate times. The
Google Groups interface (which I have used in a pinch when my real
Usenet access was not available) is notorious for acting like a message
did NOT post, so people hit 'send' multiple times. A large percentage of
people on Google Groups do not even know Usenet exists- they think they
are posting on a Google owned and run website.

Not a flame, so don't take it personally. But if you want to spend a lot
of time on here, strongly recommend you look into some other method of
news access. A lot of people block all posts from Google outright, due
to the number of spammers and simply clueless people that post from
there. I haven't been that irritated yet, but a quick look in my kill
file confirms most of the people in there are from Google.
