Has anyone ever insulated a doorknob to keep the cold air out? I was
thinking about removing it, filling the hole with foam then cut holes
for the screws and latch. Wondering what other's opinions are.

Why does gmail have a bad rep??? I think it's the best email ever and
you're the first person to say anything negative about it. What's

Since you appear to be truly ignorant of why gmail has such a bad rep,
it's for a couple of reasons: tons of clueless new posters to Usenet
newsgroups such as this one, but worse, goddamn spammers of said
newsgroups who use gmail addresses with impunity.

Not saying you're a member of either group, just pointing out why so
many of us hate gmail.

The steel rotating part will still conduct cold from one side
to another. We can reduce the apparent coldness of the
interior door handle by fitting a wood bezel and handle in
place of metal ones.

Sorry but where I live a storm door doesn't cut it. Spray foam or
something to seal the hole has to be done. I like the wood bezel idea
also. Considering that Don is from Ottawa should make it suitable
solution.

How is the "cold air" coming in?

Is it leaking out around the knob shank? There can't be a very large gap
there. maybe just an O-ring over the shank pushed against the hole it
comes through would stop most of the air flow. You could use a little
superglue to keep the O-ring in place.

Methinks you're straining at a gnat in terms of the amount of cold air
coming in there, relative to all the other air leaks in the average
house. but have fun....

Well, perhaps I did take it hook, line and sinker, but maybe I didn't.

The OP did say "cold air", not a "cold knob". And people do take cold
air leaks emanating from things like electrical outlet and swith boxes
seriously enough to try and smother them out, so why not want to
extinguish a leak from around a doorknob shank or bezel plate also?

Perhaps the OP will let us know if he was asking a serious question,
which elicited a lot of smartypants replies from other students in this
high school cafeteria of a thread, or just pulling our chains.

Speaking of pulling chains, I had some fun with a Nigerian scammer a few
years ago. Apologies if I posted this link here before, the years are
taking their toll on my memory and lately I've been suffering from some
serious CRS.*

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.

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

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.

There are patents for thermal door knob insulators
but you can make your own easily with foam rubber
pipe insulation. A 6' stick of insulation should
be enough for you to make covers for all your door
knobs. Get a small can of glue that's made for the
rubber insulation and you can glue one end closed
which will make a little pouch that can be slipped
over a doorknob. With the right outside diameter tube,
the doorknob mount will be covered too. Here are
links to the patents but I found no suppliers for
ready made insulating covers:

Original post misleading. Took it as airflow coming through.

Concerned about cold to touch:

1) They used to make rubber caps for them long ago. Probably were sold
to help prevent wall damage but really don't know.

2) Put a sock over it.

3) Wrap it with duct tape.

Concerned about the miniscule heat transfer. Go to craft store. Get a
styrofoam ball. Cut it in half. Hollow each half for half the handle.
Put over knob and glue/tape/whatever halves of ball.

In your OP you said "Wondering what other's opinions are." This
directly
answers that. You may note like them because they are ugly or
something
but they are options.

So, today I ran some new wiring, worked on refinishing cabinets,
painted
a kitchen, sized some more aspects of 2 countertops I will be
replacing
and made mailbox post from a 12' 4x4 for neighbor because his drunken
buddy backed over it.

I did that and all you have to do is worry about a few calories of
heat
coming through your ****ty knobs. And you say I'm the one who needs to
get a life?

No, I'm not going to post this 82 times to your 82 duplicate posts.

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!

5th time this msg posted. Like a damn Max Headroom transcript.

Has anyone ever insulated a doorknob to keep the cold air out? I was
thinking about removing it, filling the hole with foam then cut holes
for the screws and latch. Wondering what other's opinions are.

Thanks,

Speaking of doorknobs, here's my contribution to preserving the memories
of the olde days:

The speed of light is 1.98*10^14 fathoms per fortnight.

I have read all posts below...what a mess.

I was searching the same solution. It is now summer and my door latch is failing prompting me to take it apart to diagnose. The internal components are full of condensation as the outside warm humid air leaks into the door knob opening and is cooled by either hardware or indoor AC temperature. My searches reveal that door hardware freezes as the door hardware becomes the most prevalent source of leaking air in a tight home.

Solutions I have found so far include small rounds of bubble wrap cut to fit, the idea for spray foam (was that yours? kinda sounds messy but a good idea to displace all air). I have not seen any solution for the thermal bridging aspect.

Consider hanging out on GreenBuildingAdvisor where more people are focused on these types of issues.

Have a great day.

This post is on the bottom, there are no posts below this one. Of
course, YMMV if you have your setting different from mine.

Have never had a problem with frost on doorknobs or latches
freezing up here in canada where we have both extreme temperatres
(both hot and cold ) as well as very high humidity. Never felt a draft
from a properly installed external door latch either. This is on both
solid wood and fiberglass doors. I don't have any insulated steel
doors between the outside and "conditioned space"
